For reasons that escape me, the 1970s was the decade of the feature-length pseudoscientific documentary. 1976 is arguably the height of this phenomenon which included titles likes "The Devil's Triangle," "Mysteries of the Gods," "Overlords of the UFO," and "Beyond Belief."
"Beyond Belief" appears to be an example of a documentary where the budget was so low that no actual filming occurred except for segments involving the host, Richard Mathews. All of the mysteries it covers appear to be film footage drawn from earlier documentaries. A fairly wide assortment of subjects are covered including Cleve Backster's experiments with detecting emotions in yogurt cultures (no, I'm not making this up), ESP and dream research featuring Stanley Krippner and Douglas Dean, hypnotism and past life regression, table tipping and seances, and life after death. One long segment concentrates on English "spiritist" Matthew Manning who claims to have been involved with everything from poltergeist activity to automatic writing to psychokinesis since he was a child. The film closes with a long segment on UFO activity and covers the usual stories. An interview with "nuclear physicist and lecturer" Stanton T. Friedman is central to this.
On the surface, it appears the producers ran low on funds well into the project. The UFO segment appears to have been tacked on and was sourced from a different documentary. Furthermore, there are no closing comments by the host.
For the typical film viewer, this is a horrid mishmash of ridiculous material and should be avoided. For those who believe in such phenomena or who happen to enjoy pseudoscientific documentaries, this may be worth a look.
