Christopher Mitchum agreed to play the role of Rick for the $500 that the producers offered, as long as he could continue working as the film's second assistant director also. Mitchum was paid $150 a week as the crew member. He became the 2nd AD in between his acting scenes.
For both Joi Lansing and western star Ken Maynard, Bigfoot marked their final screen roles. Lansing passed away in 1972 and Maynard died in 1973.
In the scene where Mr. Bennett (Ken Maynard) talks on the phone with the Sheriff (about the 25-minute mark), he stands in front of a movie poster for Between Fighting Men (1932), a movie in which Maynard starred.
Shot in two weeks.
The first motion picture to feature Bigfoot, it spawned several similar films through the 70s and beyond. It was released in 1970, three years after the infamous Patterson-Gimlin short film revealed "actual" footage to the world of what may be a real Bigfoot walking through the forests of California.
