The Mysterious Monsters (1976)
I love phony Bigfoot documentaries especially if they convince me Bigfoot actually exists. "The Mysterious Monsters" had testimonials from yokel eyewitnesses and a pile of plaster footprints but what really swayed me were the "dramatic reconstructions based on actual events." In the best one, a woman is sitting in her lounge room watching TV. She hears a noise and peeps out the window beneath the blind. She sees nothing and goes back to watching TV. An ominous shadow passes behind her on the blind. Suddenly a hairy arm smashes through the window accompanied by furious growling. The woman screams. Her brother rushes in with a rifle. He gingerly approaches the front door and swings it open. Standing in the doorway, looking like giant hairy Avon Lady, is Bigfoot. Totally convincing. Narrated by Peter Graves. I guess Leonard Nimoy was too expensive.
