Watch the argument made.
Some questions are easier to grasp visually than textually. The films below — varying in production quality, none endorsed by the mainstream — present the flat-earth case in moving pictures.
Foundational
Behind the Curve (2018)
A Netflix documentary, directed by Daniel J. Clark, profiling the modern flat-earth community. The film treats the subject critically — it is not a flat-earth advocacy piece — but it documents the actual community, its key figures, and the experiments they've conducted on camera.
Most notably, the film captures a moment where flat-earther Bob Knodel runs a $20,000 ring laser gyroscope test that produces a result he had explicitly predicted only the globe model would produce. He acknowledges this on camera. The moment is genuine and damaging to the flat-earth case as the film presents it.
For viewers willing to engage seriously, this is the most professionally produced and intellectually honest treatment of the topic available — even if its conclusion is unfavorable.
The Flat Earth Conspiracy (2014)
Eric Dubay's foundational lecture/film. Lower production quality than mainstream documentaries, but it lays out the core flat-earth argument in a structured way. Dubay has subsequently become controversial for reasons unrelated to the cosmological question; the original lecture is widely circulated regardless.
Investigative
Convex Earth — The Documentary (2018)
A Brazilian production, directed by Gabriel Henrique. Notable for its scope and attempt at scientific rigor. The film documents a series of experiments (including high-altitude balloon footage) and presents the results as supporting non-globe geometries. Production quality varies. English subtitles available.
Eric Dubay: 200 Proofs Earth Is Not a Spinning Ball (2016)
A 35-minute compilation of arguments and visual demonstrations. Useful as a comprehensive reference. Some arguments are stronger than others — the value is in the breadth.
Investigations on YouTube and Independent Channels
The flat-earth research community is most active on independent video platforms. Notable channels (subject to algorithmic suppression and platform changes; current availability not guaranteed):
- Globebusters — Long-form discussions and live experiments
- Mark Sargent — Author of Flat Earth Clues, one of the early modern flat-earth video producers
- Rob Skiba — Independent researcher, late, focused on Biblical cosmology
- Witsit Gets It — Newer entrant, more rigorous in approach
- Joshua Nowicki — Documentation of Chicago skyline and long-distance visibility from the Michigan shore
Adjacent Material
Several documentaries on space-program skepticism are relevant context:
- A Funny Thing Happened on the Way to the Moon (Bart Sibrel, 2001) — Apollo program critique using NASA's own footage
- What Happened on the Moon? (David Percy, 2000) — Detailed examination of Apollo photographic anomalies
- American Moon (Massimo Mazzucco, 2017) — Italian production, comprehensive Apollo skepticism
These films are not flat-earth advocacy — they are space-program skeptic — but they share the broader category of "the public has not been told the full story about cosmology and space."
How to Watch
- Behind the Curve — Netflix or DVD purchase
- Convex Earth — Available on multiple independent video platforms; search by title
- Most other titles — YouTube, Odysee, BitChute, Rumble. Availability fluctuates due to platform moderation policies.
We do not endorse any individual filmmaker's complete worldview. Several public flat-earth advocates hold separate positions on unrelated topics that we don't share or endorse. Take the cosmological argument on its own merits; evaluate the rest separately.
