Prophecy is a 1979 horror film directed by John Frankenheimer and written by David Seltzer. It stars Robert Foxworth, Talia Shire and Armand Assante.
This is an ecological fable about the evils of industrial pollution. A novelization of the film, written by Seltzer as well, was also published, with the tagline "A Novel of Unrelenting Terror".
Filmed in British Columbia, Canada in 1978, this film marked the beginning of "Hollywood North", the major start to the development of a massive film production business in Vancouver and other areas within of the province. Since then, hundreds of "American" movies have been filmed in the Canadian province.
Some violence/gore and other scenes were deleted not because of the censors but on a decision made by John Frankenheimer. This included a longer close-up of a man's headless corpse and a shot of Katahdin graphically disemboweling Isley (both deemed "gratuitous"), a flashback to the night where Rob and Maggie have sex (deleted for time), and extensions of several scenes, including a longer tour of the paper mill and Rob fishing, which showed him falling asleep and later waking up in the sun.
The original concept for Katahdin was considerably more terrifying than what would eventually show up on screen. However, when director John Frankenheimer saw the concept, he suggested that it should be altered to look more "bear-like". Interestingly, the original concept was actually quite close to the poster art.
Frankenheimer considered Prophecy
a film with far more potential than what he eventually delivered, ostensibly due to the high peak of his alcoholism. The scene where Katahdin swats the boy in the sleeping bag to smithereens is regarded as unintentionally hilarious by many viewers in this attack scene.
