Made with the assistance of the National Film Board of Canada, this 1990 Canadian mockumentary about the flat Earth theory including the fictional story of the fatal polar expedition by Andrea Barnes.It was created to teach critical theories and debunk flat-earth theory, though some flat earth adherents continue to use it as if it were a non-fiction, serious documentary supporting their beliefs.
