“If you’ve taken home movies of Bigfoot, the monster that roams the Northwest, it could be worth more than 10,000 to you. Producer David Wolper, will pay at least that much for usable footage in his new dramatized documentary Bigfoot. The Mysterious Monster.”

September 12th, 1975
The Mysterious Monsters was the first movie to feature the home movie taken by Roger Patterson in 1967 reported to show a Bigfoot. Anthropologist Grover Krantz was interviewed and said he believed the film to be authentic. Famed Bigfoot hunter Peter Byrne was also featured and gave insights on the hunt. Robert and Frances Guenette are credited as the authors of a 160-page book adaption of the film.
The film was later featured in an episode of Cinema Insomnia.
