Originally released as Secrets of the Gods. It was so successful that two years later, greedy theater owners decided to release the exact same movie under a different title "The Force Beyond." Moviegoers were upset, they complained to the distributor that they'd already seen the movie.
William Sachs made this as a silly satire aimed at UFO/Bigfoot enthusiasts. Sachs interviewed actual people who claimed to have been abducted by aliens or confronted Bigfoot. He felt they were all "bizarre." He went to a UFO convention in Fort Smith, Arkansas, and shot a lot of people in distorted lens while they were being interviewed to make them look round, like through a fish-eye lens, in order to enhance the strangeness of the topic. He thought moviegoers would understand it was a spoof but several viewers were offended as they had expected a totally earnest take on the subject. He said, "I thought it was a satire on what people thought the secrets of the gods were, how spacemen came and made it with Bigfoot and that's what became us. But a lot of people took it seriously."
