You've probably seen this image of 'Bigfoot' from the 1967 Patterson-Gimlin Film, shot in Northern California. It's the most well-known piece of footage that supposedly proves the existence of Bigfoot.

However, a 2004 book by Greg Long proved that it was all a hoax: a local man, Bob Heironimus, told Long that he wore a suit. However, the stunt may not have been done with ill intentions. Even though Roger Patterson never paid anyone involved with the film and had charges filed against him to get him to return the camera he used, he likely did the whole thing as a stunt to provide for his family, as he was sick with cancer.
