recaps of the top 'ask me anything' interviews from reddit and more...
We are Daniel J. Clark, Caroline Clark, and Nick Andert. We made the documentary "Behind the Curve" about Flat Earthers. AUA!

"Behind the Curve" is a documentary about the Flat Earther movement, and the psychology of how we can believe irrational things in the face of overwhelming evidence. It hit Netflix a few weeks ago, and is also available on iTunes, Amazon, and Google Play. The final scene of the film was the top post on Reddit about two weeks ago, which many people seemed to find "interesting."

Behind the Curve Trailer

It felt appropriate to come back here for an AMA, as the idea for the movie came from reading an AskReddit thread almost two years ago, where a bunch of people were chiming in that they knew Flat Earthers in real life. We were surprised to learn that people believed this for real, so we dug deeper into how and why.

We are the filmmakers behind the doc, here to answer your questions!

Daniel J. Clark - Director / Producer

Caroline Clark - Producer

Nick Andert - Producer / Editor

And to preempt everyone's first question -- no, none of us are Flat Earthers!


EDIT: Thanks everyone!

I watched the doc just last week and really enjoyed it.

I particularly liked the time you gave to members of the scientific community to talk about how science may have failed these people, rather than just lambasting them as idiots.

It seems that facts established by the scientific method won't convince these kinds of people, so what do you think the scientific community could do to engage more with the growing anti-intellectual movements (flat earth, anti-vax, climate change denial etc) to avoid them feeling isolated and grouping together around damaging ideas?


This gets to the heart of it. A lot of people have rightly pointed out that arguing with Flat Earthers is pointless, because they’re so entrenched that no evidence will move them. To an extent, that’s true for many of them, and it’s especially true for a lot of the ones you encounter online who are trying to get into debates about the shape of the Earth. For them, they’re starting from a place of ‘Argument is War,’ as Per Espen put it in the film, so engaging with them might not be particularly worthwhile (although it is worthwhile for people to see that science has answers to their questions, so someone susceptible to those beliefs doesn’t see a bunch of unanswered questions and fall for the ‘science has no answers’ trap).

However, there’s something to be said for respectfully engaging with people in a positive way, especially in real life, because it shows them that the people with opposing arguments are operating in good faith, and opens their minds to accepting evidence from them. One of the biggest issues with conspiracy theorists in general is the tendency to ‘other’ people that they don’t know, and apply malicious motivations to them, which allows them to dismiss any evidence coming from them out of hand.

Spiros, from the film, has now gone on two hangouts with a group of Flat Earthers, and they’ve all been very friendly with each other, and we hear they may even do some experiments together. They see now that a high level scientist isn’t just a nameless enemy, but someone who respects them as people, and they’re open to listening to him.

So you’re probably not going to change a Flat Earther’s mind in a single argument online, but continued respectful engagement from people on ‘the other side’ will hopefully open their minds over time and make them more likely to accept the evidence.

  1. How was the documentary received in the FE community? - Do they think it is an honest portrayal or have they accused you of misrepresenting them?

  2. Related to the second part of the first question: If they feel misrepresented, are you afraid that this could cause a bigger rift between FE and others? (I am aware that you are trying to promote more understanding in the documentary, but I can imagine it could be viewed differently from another perspective).

  3. Did you ever have mixed feelings about what to show? I imagine that the person with the gyro (can't recall his name) got very upset when you showed the conversation about the experiment not working and he thought it was private. (Personally I think this is the best... We need to hear the honest statements like this... politicians would be so much easier to get a read on).

  1. We've been accused of 'not including flat earth proofs,' because, well... we were never shown a single proof that we judged to have merit, and the film was more about the psychology of belief anyway. But, as you can imagine, this led to anger amongst lots of flat earthers. Similarly, those doing the experiments feel that we misrepresented the outcome of the experiments, because they still hold that the earth is flat and that the results can be explained away, while we hold the opposite view.

  2. That's a great question. Many also think the documentary is a 'controlled opposition hit piece,' so suffice to say that they'll probably never be receptive to us again, but that doesn't mean that they can't be receptive to others that engage respectfully with them. As mentioned in another answer, Spiros has been engaging positively with them since the release, and that's despite the fact that he was in the film.

  3. In that particular moment Bob knew he was mic'd up. He thought that they'd have the gyro 'figured out' by the time of the release. In fact, he thinks he does have it figured out (he has an explanation involving the aether, which has been experimentally disproven to exist). There are things we decided not to show in the film, because they felt exploitative and not in service to any particular larger point. We had no desire to humiliate people, but it was important to us to deliver an honest portrayal.


I teach social science to 16-18 year olds, and I put a lot of effort into teaching them critical thinking. I recommended your documentary last week, after a lesson about conspiracy theories and how it can lead to hatred and violence, after one of them asked me how they could tell the difference between critical thinking and conspiracies. Your film gives such a beautifully clear picture of this difference, focussing on the scientific method. What do you think we need to do MORE or LESS of in the educational system to nurture curiosity and creativity, at the same time as respect for science and established truths? Edit: OMG Gold! I shall cherish it forever, thank you!


This is a great question. We think part of the problem is making it ok to admit you're wrong, or that you don't know something. That's an incredibly difficult thing for anyone to do.

We think inoculating people against the Dunning Kruger effect by making it clear just how vast and complicated many concepts are could certainly help. It's important for people to have respect for how much time and work experts have put in to learn about their various subjects.

Another thing that's super important is internet and media literacy. Because the internet's enabled confirmation bias to a massive degree, it's very easy to seek out and find confirming information and not critically consider the source.


Has there ever been a compelling argument from a flat earther? If so, what was it?


Some of the questions Flat Earthers raise are certainly interesting, because the science behind them isn’t immediately intuitive — however, when you look into it, the real answer makes perfect sense. For example, a common Flat Earth talking point is that the rotation of the Earth should cause us to ‘fly off the globe,’ like water off of a spinning tennis ball. In reality, there is a force exerted from the rotation of the Earth, which actually makes things weigh slightly less at the equator than the poles, but that force is so much weaker than gravity that that small weight difference is the only effect. The way Hannalore put it in her interview, in an answer that got cut, is “when you take a really big number, and subtract a really small number… it’s still a really big number.”

So we would say their most “compelling arguments” are actually gateways to learning about some interesting science.


Any moments where the frustration of such ignorance almost broke you riding the process of making the film? Or any subjects you had to walk away from?


Caroline -- We chose the topic of "flat earth" because it was a more palatable window into conspiratorial thinking than some other conspiracies, which would allow us to have a conversation about the psychology of conspiracies with a broad audience. At the end of the day, however, a lot of flat earthers believe in other, more harmful conspiracies. Saying the earth is flat doesn't necessarily hurt anyone, but saying a mass shooting didn't happen or saying that vaccines are harmful is harmful for a myriad of reasons. It was really hard to listen to these sorts of conversations without engaging with our subjects on camera.

Nick -- It was definitely hard to listen to them discussing Vegas shooting conspiracies, because one of my friends was actually there (she's fine).

Daniel -- On almost every shoot. Sometimes after shoots I would call Nick and Caroline to just talk through everything I heard.


What were the first steps you took to make this documentary? How did it go from idea to actual execution?


Nick -- I saw a reddit thread and discovered people actually believed it. We'd been looking to do our first film on our own for awhile, and this seemed like a great subject. After discovering that a conference was happening, we found a lot of our subjects by looking at their speaker list and determining who seemed influential and interesting. Mark was at the top of the list immediately. His number was publicly available, so we called him and he was on board.

We knew we wanted critical analysis in the film too, so we reached out first to Dr. Joe Pierre because he had written a column on the psychology of flat earth beliefs. Our first shoot was his interview, because we figured that perspective would be valuable before we went on shoots with flat earthers. Soon after, Daniel went to Whidbey for three days to shoot with Mark, and we felt that we had a good movie on our hands.


I both loved and loathed your film. I loved it because it was fair and thorough and, at times, hilarious and endearing. I loathed it because it brought back many painful memories for me.

I used to be a 9/11 truther. I was... deep into it. I believed everything short of the holograms and space laser stuff, I read about 30 books on the topic and watched/distributed dozens of "documentaries", I ate up every amateur radio and TV show on the matter, I religiously participated in the websites/forums, I evangelised to friends and family, etc. etc. etc.

Watching your film, I was saddened and disheartened that all of the subjects you encountered were identical in every respect to the people I encountered, and indeed the person I was:

  • The almost Rain Man-level memory for every tiny detail of the issue and its history
  • The unquenchable enthusiasm and willingness to sacrifice crazy levels of time and energy to the issue
  • The way contrary evidence is never, ever accepted, ever
  • That the idea of changing your mind has a cascading set of side-effects for the very essence of your life and identity, including having to say goodbye to your entire circle of friends because they'll now consider you a shill/sellout
  • The sad and obviously-biased attempts to run experiments and meet science head-to-head
  • Watching intelligent, successful, professional people destroy their reputations and their personal lives
  • The way belief in one conspiracy theory is like opening the floodgates to every other conspiracy theory out there, because of how helpless you are to reject any of them given your complete distrust of reality itself
  • The belief that your issue is the THE issue of our times and that everything else in the world is slavishly entangled with it somehow
  • The social isolation and the feeling that you've found something you can throw yourself into and become a change-maker in the world alongside a new set of like-minded friends
  • The way key figures take positions of authority in the "movement" (the jealousy, the in-fighting, the "high priests & priestesses", the relentless radio and social media choir-preaching from the movement's figureheads, and so on)
  • The unstoppable torrent of "documentaries" and e-books on the topic
  • The non-stop conferences and outreach/activism via billboards and newspaper ads, draining the bank accounts of the credulous in the process

It's all there, it's shocking and frightening to me that you could replace "flat earth" with "9/11" and leave everything else unchanged, and it would be indistinguishable from the real 9/11 truther phenomenon. This makes me much less inclined to mock flat earthers, despite their conspiracy theory being only one notch about Holocaust denial in terms of how despised and derided it is.

I don't know exactly how I got out of it, but it was not by being shamed, belittled, mocked, or lectured by debunkers. The mind of a believer in this stuff is so tortured already that adding more needles to the fingernails of his worldview with derision is only entrenching him further. When you are preaching this sort of stuff to non-believers, you have this constant agony in your skull, like your brain is being punched the more you talk about it, and telling baffled family, friends and complete strangers about the issue makes you agonise more and more. You take the pain as evidence that you're fighting the good fight, standing up to the elites, resisting thought-policing and brainwashing, throwing yourself against the machinery of oppression, and so forth. After you get out of the movement, you realise that the pain you were feeling was your cognitive dissonance screaming at you to stop and to let go of these insane beliefs for the sake of your own dignity, almost as though your good sense was a prisoner within the bounds of its own brain matter. I was lucky that I got out before I ruined any relationships with friends and family, but I'm absolutely certain that luck was the only thing I had going for me.

The only way I know to get out of something like this is to have something happen in your life that interrupts your obsession for long enough that you to come back to it with a much less vulnerable and bewildered mind, with a sense of distance and a renewed sense of perspective, with enough time for your sense of identity to "reset" (it's like deleting a reddit account and starting over), and in doing so you realise how much better off you are without this stuff in your life (the knowledge that you're harming your life/reputation is part of the "anti-brainwashing resistance" thing I mentioned before, so the fact that you are doing damage to your life isn't enough, in and of itself, to discourage you. On the contrary!).

For me, the interruption was a combination of severe bouts of mental illness (vulnerability to which was undoubtedly a factor in me finding my way into the 9/11 truther world), and later finding a different community which gave me all of the things the 9/11 truther community gave me, but minus all of the baggage and suffering (it was a musicians community in my case, but everyone has a hobby that isn't a conspiracy-based one, so focus on that whoever you are! And don't let them bleed into each other, keep them separate). I don't recommend the "mental illness as a key to intellectual liberty" route of course, but you just need to unplug somehow. Even if it's just a private challenge you set for yourself. For instance: can I avoid all things flat earth for 3 months, including not checking the websites, consciously resisting the urge to view news events through the lens of a belief in a flat earth, not mentioning or talking or responding to conversations about it online or IRL, not watching documentaries or listening to podcasts on the topic, etc.? Complete disconnection. Use the free time you now have for life-affirming and social things. Go for walks, photograph nature, bake cakes, play soccer with old mates from school, visit museums and attend plays/theatre, join a book/movie/music club where you meet people IRL, do all of these things without ever letting your particular conspiracy theory of choice creep into it. You owe it to yourself to give yourself the best chance of a happy life. Staying inside a movement of this sort is not the way to achieve psychic peace. Please try it: disconnect, unplug.


Thank you for sharing! This is a really valuable perspective. The concept of needing to unplug absolutely applies to flat earthers too -- a lot of them get to the point where their lives are consumed by flat earth, and they spend all of their free time listening to flat earth podcasts, discussing flat earth theories, etc., just like you describe.


Mark Sargeant seemed pretty tame, the guy who bounced golf balls on hammers seemed a little less tame, but were there any WAY OUT THERE personalities interviewed for this? I'd like to hear a story about them!


Anyone we spent a significant amount of time with is in the movie. We met some interesting people at the meetups and convention, not all of whom made the cut. There was one gentlemen who played for us his flute 'tuned to the frequency of the sun,' another who was adamant that you didn't legally need a license plate to drive... there's a bunch online spreading some fun conspiracies about us. Our favorite one is that we had the default squarespace favicon on our website for awhile, and that is apparently the 'Black Cube of Satan,' making us Satanists.


did you find yourself falling into their beliefs at all? Were they spending a lot of time trying to convince you guys what they knew was true? Rather than just convincing the viewers who’d watch it. At any points did they feel like what you were doing was maybe “making fun” of them? I loved the documentary it was great!


Daniel -- I never felt myself believing what they believed, but the idea of believing in flat earth started to feel normal to me during shoots. When you immerse yourself in a community like this, it's very easy to feel like this thinking is very normal, but often as I was driving away from a shoot, it would come over me like a wave that these people truly believe the Earth is a flat plane and it was a very strange feeling.

People would come me to us during filming and when I told them I wasn't a flat earther, they would simply say "you will be soon," or they'd ask what reasons I had for not believing in FE. They were usually very kind about it and rarely did I ever feel cornered. I was always very respectful, but would be honest of my feelings if they pressed me on the issue.


What’s your favourite piece of footage that you just couldn’t use?


Caroline -- I love the 'water-less shampoo' bit in this deleted scene --

Nick -- There's a deleted scene in our iTunes Extras where Chris is showing us around his insane apartment, and he talks about a device he made to 'dissipate chemtrails.' Plus, there's part of the Nathan interview where he goes on about how many 666s there are in scientific constants, which was... whew.

Daniel -- In Salem there's a World War II monument that is an Azimuthal Equidistant projection of the earth, which is what flat earth maps usually are, and Mark couldn't believe that it was there, and was certain that I knew about it and led him to it (I didn't).


Did you meet anyone you guys would consider as someone likely suffering from mental health issues?


There are definitely people in the movement that have an inordinate amount of paranoia, which feeds conspiratorial beliefs... but on the whole, the vast majority of people who are into flat earth don't come off as having mental health problems. Rather, they're people who tend to value subjective experience and intuition over objective evidence, which is something that's widespread.

Our brains like to think of flat earthers as "uneducated" or "crazy" because it makes us feel better about ourselves. "I'm not like them because I went to college/get my information from X source and not Y source/etc." We want to think we're not susceptible to this kind of thinking, but in reality, all of us are.


Did you enjoy your interactions with the flat-earthers you spoke to? Do they seem like regular people outside of this belief?


The people we interviewed in the film were generally very friendly and open to us. We talked about a ton of things other than conspiracies and flat earth (movies, music, food, etc.). It's easy to connect with people if you're respectful. And when not talking about flat earth, you wouldn't know most were flat earthers. When we DID talk about flat earth or conspiracies, that was usually on-camera and it was less of a conversation.

Special mention: Mark's mom, Patti is extremely kind and generous and always baked us cookies, scones or offered us dinner. She's wonderful.


I watched the movie a week or so ago, when that clip from the end showed up on Reddit. I'm curious about the interview process with most of the highlighted personalities. How much of their input was prompted by questions, and how much did they just talk about and offer up on their own?


For most of them (Mark especially), when you ask them a question, they'll speak for a long time on a lot of different topics. They usually have things they are eager to talk about.

"Do you know they made up dinosaurs," for example -- 100% unprompted.


Did you ever ask the Flat-Earthers who 'they' was and what 'they' got out of it? One of the biggest sticking points to me about conspiracy theorists is that the benefit to 'they' is never explained :/


It really differs for each and every one of them. Mark's view, which he expresses in the film, is that scientists would 'lose their power' if they admitted that they'd been wrong for so long.

The most cogent explanation probably comes from the Infinite Plane crowd, who think there are utopian continents on the other side of the ice wall reserved for the rich and powerful.

'Most cogent' is a relative term in this case, of course.


Towards the end of the documentary Mark Sargent mentioned that he felt he could never leave the Flat Earther movement. Did any of you also get the vibe that he has his doubts but felt obligated to remain a leading figure in the community?


We do. We think he gets such a huge amount of validation from this that he has a mental block from acknowledging any countervailing evidence. We think it's really easy for people in general to lie to themselves, and he has plenty of motivation to do so.


Did any of the participants in the doc change their beliefs after filming?


No one we filmed has changed their minds. Hard to say if it’s had much of an effect on other Flat Earthers. The general talking point in the community has become that we’re a “controlled opposition hit piece,” and that the experimental results featured in the film thus can’t be trusted. The Flat Earthers we filmed know that we’re just normal people, but they still have found ways to explain away the experimental results.


Why do flat earthers perform experiments if they won't accept the results?


Honestly? The ones who do actually believe it'll give them a flat result. But they're not in a place to let their beliefs be falsifiable, so instead of switching views you get mental gymnastics. They don't tend to set up experiments with a firm acknowledgement of 'if I get X result, that means the Earth isn't flat.'


What was the most interesting thing you found out about their community, beliefs or just them in general when you were interacting with them?


We expected all flat earthers to be very religious, and that their flat earth beliefs would stem from that. It turned out that, while that was certainly common, the biggest predictor of flat earth beliefs was conspiratorial thinking. A lot of the main people we interviewed were not particularly religious, but very conspiratorial.


Did most of these people also believe in multiple conspiracy theories? As in, is this just conspiracy theorists just latching on to a new topic, or are they just mostly only flat earthers?

(off to go watch it on Amazon now!)


Flat Earth is sort of the bottom of the conspiracy rabbit hole. To even be in a place to entertain it, you have to have accepted so many other conspiracies. If you bounce a conspiracy off of them, they probably believe it. Or at least, they're not willing to immediately discount any conspiracy as obviously false.


How did you get the people to be in your documentary? Did they know this was about the psychology of flat-earth conspiracy theorist?


We were clear that we were not flat earthers, and that we were making a movie about the people in the flat earth movement, as opposed to the question of whether the earth was flat or not. We did not tell them that we were interviewing scientists and psychologists too.

Most of them were very willing to talk to us right away. They feel that any opportunity to discuss flat earth is a net-plus.


Why do you think people should watch this documentary?


One of the big reasons we made the doc is because we felt Flat Earth was a good case study in the growing trend of science denialism and conspiratorial thinking. It’s easy to dig into the thought processes underlying these trends by looking at how Flat Earthers come to and justify their beliefs. And we think a lot of people on the science communication side could engage conspiracy theorists and science deniers in a more effective way. There’s a lot of smugness that tends to entrench people in their beliefs, which is not helping to mitigate the problem.


Did your crew point out the “Press to Start” button at the NASA center after filming? That scene got a good laugh out of me.


Daniel -- I was alone on that shoot, and I did not point it out. Here you can see it from the other angle!


How did you choose the the science folks to be part of the doc? Like I recognize a handful of their names, but Hannalore and the male physicist with the accent were new to me. Is there an active anti-flat earth community or did you just pick individuals who could speak popsci but who had real credentials?


Dr. Pierre had written a column on the psychology of flat earthers.

Hannalore had experience in science communication from giving a talk at an Astronomy on Tap.

We were a fan of Tim's writing beforehand, and he was wonderful in a film our friend made called The Mars Generation, so we thought he'd be a great addition.

Stephen Hagberg was the high school science teacher of one of our colleagues.

Per Espen Stoknes had written a book which is one of the definitive texts on the psychology of climate change denial.

Spiros was recommended to us by a colleague who had worked with him before on another project (I forget exactly which).

And Scott Kelly of course is Scott Kelly.


By making the doc and sharing these views to the masses, do you feel you risk legitimizing these people and their positions?


It's certainly a question we struggled with. However, we feel critical analysis of these trends is important in order for us to learn how they come about and how we can address them. If no one on the other side ever talked about flat earthers, or the many harmful conspiracies like Anti-vaxxing that are becoming prevalent, they would still spread on their own accord. We were careful not to give undue legitimacy to their beliefs in the film, making sure it was understood several times throughout that there are easy answers to the questions flat earthers raise (like with Hannlore and the planes, or Stephen with inertial frames of reference).


I found the documentary fascinating. The way the guy at the end explained away the failed experiment was awesome. Did he ever come around and think maybe the earth was round?


He did not, and in fact maintains that it was simply "one observation among many."


I would have had a tough time listening to Patricia talk about conspiracies about her, and not interrupt to point out her hypocrisy.

Did any of you ever have an accidental outburst when listening to something difficult to hear? To a lesser extent, was there ever heated debate off-camera?


Daniel -- I once burst out that "gravity isn't a theory" because it was a long day and I was really tired...


Did the Flat Earther ever answer the kid's question "how tall is the dome?" And was that kid a flat earther or just brought along by flat earther parents?


Haha, he actually did, yes -- it was cut out just because the flow was better to go straight from him asking how old the kid was into the climax. What he said was, "go outside and look at Chris Pontius's models -- basically that." So it wasn't a very detailed answer.


Have you heard about moon truthers and australia deniers? Could be two more documentaries there ¯\_(ツ)_/¯

(Credit goes to me ty)


I mean, we've never been to Australia...

Sounds pretty fake.




There definitely does seem to be a link between conspiratorial thinking in general and a need to find some sort of validation. It's easy to feel left behind in the modern world, when we're all told that, in the age of social media, everyone has a voice and everyone can be impactful. When that turns out to perhaps not be true for many people, belief in conspiracies can be comforting, because now you have some secret knowledge, and pushing the 'truth' gives you purpose, gives your voice meaning, and other people in that conspiracy community value you. So conspiracies like flat earth can absolutely fill a hole in some people's lives.


Hi folks! Was wondering out loud today with Mrs Cardlinger: did any of the flat earthers you interviewed think the other planets in the solar system are also flat? Or that they don't exist as planets (they're "illusions in the sky"), or...something else?

I couldn't conceive they'd think other planets were spheroid but Earth was the exception to the rule...

Was a fun watch - thanks!


None of them see them as other planets but rather have some other explanation. Mark believes they're a projection on a dome. We're honestly not sure what precisely other people think... none of us can recall hearing an explanation from someone who doesn't buy into the 'projection' theory.




We made the film in a very scrappy, self-funded way, with no distribution. We ended up getting interest from sales agents, and they shopped the film around. We were very fortunate that Netflix was interested in licensing it on their platform.


Im under the assumption most flat earthers are poorly educated. Is this true?

And if so, Was there ever the case that there was a well educated person believing the earth is flat?


We get this question a lot, possibly because it's comforting to think of flat earthers as uneducated, as different than us. While it seems intuitive, it's not as simple as that. In fact, research has shown that people who are more educated can then use their reasoning abilities to explain away evidence.

We recently met Asheley R. Landrum, Assistant Professor at Texas Tech, who is performing research about science curiosity. Her grad students were at the Flat Earth Conference in 2017 (the same one in "Behind the Curve") asking questions to flat earthers about how they found the conspiracy and who their sources are. You can read more about her research here.


How often, during filming, did you each look at each other and say “what the fuck?”


Every day, djchuckles. Every day.


After watching your documentary I have concluded flat earthers are not idiots, not unsuccessful, and they typically don't "live in their mom's basement." I also discovered flat earthers are not dog people. Does that hold true among all the flat earthers you interviewed?


Nick -- Bob and Jeran both actually have dogs! The excess of cat shots is more a function of how much Daniel and I love cats. (Caroline is also... 'ok' with cats!) I mean, if a cat was doing something funny, it's not like I was going to leave that out...

Plus Mark's cat Bitsy is the greatest cat on this round earth.


if this AMA is still going on and this hasn't been asked.....
Did any of the Flat Earthers explain why no one has been to the edge of the Earth? Or this wall they claim exists around the edge?


Pretty much all of them believe there's some military presence keeping people from exploring too far down there. You'd think that getting on a boat and circumnavigating Antarctica would answer their questions though.


Did you ever try to arrange a meeting between Mark/What's-her-name and the physicists you spoke to?


It felt too contrived to us to organize that. We wanted to film this as a verite doc, and not interfere too much with anything that was happening.


How much of a threat do groups such as the flat earthers pose? are they harmless eccentrics or should we view their complete denial of science more seriously?


They're more symptomatic of a larger denial of science than anything. Someone believing in flat earth on its own isn't necessarily harmful to society, but anti-vaxxers and climate change denial, on the other hand, are incredibly harmful, and these belief systems often overlap.


Do you believe most Flat Earthers are serious or just being Ironic / trolling?


Daniel -- I didn't meet a single flat earther that seemed to be faking it.


What's your favourite sandwich?

Would you make it on Flatbread or normal bread


Daniel -- Growing up in Philly, it's always Italian hoagie. On a roll.

Caroline -- Flatbread over a sandwich any day.

Nick -- Reuben or Cubano. I'm agnostic on the bread.


Did you come up with the name of the project before filming?


Nope, while filming.


What is the strangest 'proof' you've heard from a Flat Earther?


We just found this recently, but the argument put forth by a flat earther in this video (a scimandan response to it) is just... baffling.


Is the earth flat?


Did you bump into Eric Dubay during your filming?

Dude is a nutjob lol


We're aware of Eric Dubay, but he was in Thailand, and we were only filming in the US. Plus, he said some very bigoted things around that time, so we weren't eager to interview him.


As a non scientific/ normal guy, what is the best argument i can use to convince flat earthers that the earth is indeed round?


Some good simple ones are:

  • The motion of the stars (star trails) perfectly corresponds to a globe earth, and would be impossible on a flat earth. You can point a camera at the sky and take a timelapse anywhere on earth, and the point around which the stars rotate changes based on your latitude, and you'll see different stars in the northern and southern hemispheres.

  • Sometimes at sunset you can see the sun cast shadows on the clouds from underneath. This would be impossible on a flat earth model.

  • Direct flight times between continents in the southern hemisphere (there's not many, but there are a few, and anyone can book a ticket on them) correspond perfectly to the globe, and would be impossible on a flat earth.

This video also shows how the motion of the sun doesn't correspond to a flat earth model.


What do you think would happen if private space flight started taking these folks up into space to see the earth and literally give them a different perspective?


We actually discussed this in our interview with Dr. Pierre, in an answer that didn't make the final cut. He opined that there would be a range -- for many, it'd be enough, but there'd be a core group of people who would explain away what they were seeing through the window as some kind of trick. And the rest of the flat earthers who did not go to space would almost certainly write off someone who did go and convert as having been an agent and a liar all along.


Do you think you can make out reasons for the growing science denialism?


In our view, one of the main drivers is the degree to which the internet has enabled confirmation bias. It's now so easy to seek out an echo chamber that it actually takes work to seek out disconfirming information... and seeking out disconfirming information just isn't an instinct most people have. It needs to be instilled. There's a lot more nuance to the issue beyond just that, of course, but we feel it's one of the big reasons.


WHAT IS ICED APPLESAUCE??? I have to know.


Imagine applesauce. Imagine it's very very cold. What you have just imagined is iced applesauce.


I’ve been helping a friend of mine on a long feature length surf documentary. It’s gained some traction and recently was chosen as the ‘closing night film’ in an international film festival.

Do you mind if I ask how you went about getting your film on Netflix? That is the next goal for their film, but it doesn’t appear that there is a clear path to doing so. Perhaps hiring representation? Any insight on how you achieved this would be very helpful!


Having it at the film fest, especially as a heavily featured film, will be a huge boon. What we did, and what you'll probably want to do as well, is get a sales agent to represent you and then shop the movie around. It's not strictly necessary, and at market festivals in particular you can negotiate directly with some distributors if they send reps there, but getting a sales agent to do the heavy lifting for you makes things far easier. How to get a sales agent interested is a trickier question. It helps a lot if a film is getting positive press, so chasing down any press opportunities is a good idea. Also, using the festival as an opportunity to meet as many people as possible and feel out who might be able to connect you to an interested agent is helpful.


2 questions

What opinions do you have on this topic (among others) being one of the topics being perpetuated by Russia in the known efforts to destabilize America?

Do you have any thoughts on the idea that you are talking and thinking about a subject that people are purposefully making efforts to convince people to talk and think about?

  1. We actually became friendly with the filmmakers of Active Measures while at Hot Docs (they're lovely people), and they asked us this same question, because Russia has been shown to be pushing some conspiracies like anti-vaxxing. We haven't seen any evidence that flat earth is anything but a home-grown phenomenon, but if someone uncovered that Russia had been pushing it, we wouldn't be particularly surprised.

  2. We hope that by discussing it in a context that makes it clear the subject is wrong (proven by them with their own experiments, in fact), it will not result in recruiting more flat earth believers, and will instead result in a better understanding of how to communicate with flat earthers. Whether that will pan out remains to be seen, of course, but that's our goal.


Im late to the show here, but I just watched the film. I saw the icon for it on netflix but this reddit post finally gave me the oomf to see it.

One part of the film covered Mark watching the eclipse. He sort of nonchalantly says that the sun was eclipsing itself. I stood up and immediately asked out loud "Did he just suggest that the sun turned itself off and then back on again?"

Is there more to this? This seems like a pretty bold statement to make and I am curious to see any more of his reasoning behind it.


Not following up on that is a regret of ours. He didn't express that view while at the eclipse, but rather on a show with patricia later, and by the next time we shot with him in person, we simply forgot to add that to our questions.


Technical question! The lighting and composition of your interview material was fantastic. What was your camera setup?


Daniel — love technical questions! For our sit down interviews, we usually had 2 cameras, either canon c300’s or song fs5’s with Zeiss lenses: one long (50 or 85mm) one a little wider (24 or 35mm depending on how much space we had). Usually a kino flo diva light with plenty of diffusion as the key and a rim light behind, and we welcomed natural light whenever possible. We liked to have as much room in the interviews to avoid being super tight on our “talking heads”.


In the making of the documentary, have you met some, if not many, people who were "converted" when their experiments proved them otherwise? Or is it the same psychological circus with all of them?


We were on a podcast a few weeks ago that included one former flat earther, which shocked us, because I don't think we'd met any until that moment. He converted specifically because he saw experiments continuously proving them wrong. So it can be done!


Did you pay any of the people that agreed to be interviewed for the film? If so, do you think any of them may have exaggerated their beliefs so their footage would be more likely to be used?


We don't pay anyone for interviews or appearances as a rule. It creates an inherent conflict of interest just like you describe.


How does one become a Flat Earther? What's the process that leads to that?


In our experience, there always seems to be a 'gateway conspiracy,' often 9/11 conspiracies. Then they move onto things like moon landing conspiracies. Then eventually they wind up at flat earth.


Do Flat Earthers actually exist? All I ever see is Reddit making fun of them, but I’ve never actually heard someone claim the Earth is flat.


Fun documentary you guys! Hard to believe people really think the earth is flat and that this didn’t charge their minds! You mentioned the idea to make a documentary steam from a here, was this your first film or where you guys already in the business? Also how long did it take to make the film? Thanks for doing this AMA!


The three of us have all worked in documentary in various capacities for most of our careers, but this was the first film we made ourselves. It took almost exactly one year from start to finish to make the film, which is quicker than the average time for a doc.


How did you guys make it look like the earth wasn't flat? CGI?




Who chose the music for the film? I really liked a lot of the tracks in there, and the choice of Real Estate's Horizon was pretty funny.


Nick -- That'd be me! Funnily, we're listening to Real Estate on shuffle as we answer questions. Choosing music is one of my favorite parts of filmmaking.
