Examining the Patterson film

The most famous recording of an alleged Bigfoot is the short 16 mm film taken in 1967 by Roger Patterson and Bob Gimlin. Shot in Bluff Creek, California, it shows a Bigfoot striding through a clearing (see figure 2). In many ways the veracity of the Patterson film is crucial, because the casts made from those tracks are as close to a gold standard as one finds in cryptozoology. Many in the Bigfoot community are adamant that the film is not-and, more important-cannot be a hoax. The question of whether the film is in fact a hoax or not is still open, but the claim that the film could not have been faked is demonstrably false.

Grover Krantz, for example, admits that the size of the creature in the film is well within human limits, but argues that the chest width is impossibly large to be human. “I can confidently state that no man of that stature is built that broadly,” he claims (Krantz 1992, 118). This assertion was examined by two anthropologists, David Daegling and Daniel Schmitt (1999), who cite anthropometric literature showing the “impossibly wide” chest is in fact within normal human variation. They also disprove claims that the Patterson creature walks in a manner impossible for a person to duplicate.

The film is suspect for a number of reasons. First, Patterson told people he was going out with the express purpose of capturing a Bigfoot on camera. In the intervening thirty-five years (and despite dramatic advances in technology and wide distribution of handheld camcorders), thousands of people have gone in search of Bigfoot and come back empty-handed (or with little but fuzzy photos). Second, a known Bigfoot track hoaxer claimed to have told Patterson exactly where to go to see the Bigfoot on that day (Dennett 1996). Third, Patterson made quite a profit from the film, including publicity for a book he had written on the subject and an organization he had started.

In his book Bigfoot, John Napier, an anatomist and anthropologist who served as the Smithsonian Institution’s director of primate biology, devotes several pages to close analysis of the Patterson film (pp. 89-96; 215-220). He finds many problems with the film, including that the walk and size is consistent with a man’s; the center of gravity seen in the subject is essentially that of a human; and the step length is inconsistent with the tracks allegedly taken from the site. Don Grieve, an anatomist specializing in human gait, came to the conclusion that the walk was essentially human in type and could be made by a modern man. Napier writes that “there is little doubt that the scientific evidence taken collectively points to a hoax of some kind.”
