This is very funny stuff. It's not actually documentary, most of it is directed, but it has tendency to be seen as "real documentary". It's loaded with funny stuff-quotes like "Dionis, god of ecstatic intoxication", rite in Finland with "severed pig head painted in black (wtf?!?!), satanists in black mass that are afraid to show their vagina (shy satanists?!?!?), but funniest of all is part with voodoo rites, where narrator first mentions St. Hypnosis (?), and then there's some creepy footage of ritual with young girl sitting while some "priest" decapitates chickens and goat on her head. That's not directed (I hope), but the funniest thing is when narrator says that "they put feathers of dead birds on girl's head as the symbol that she may fly above unhappiness and poverty like these birds!" Hahaha, yeah right, they flew really high. There is also LaVey, who is funniest of all. But the creepiest thing is psychedelic flower music that's in background all the time, and no matter how ridiculous movie is, it was scary for me to look at some freaky voodoo cemetery ritual with psychedelic groove in the background. Seariously, it's obvious that this movie was supposed to have educational tone, witch maybe it had in 1970., but today it looks like poor Christian mockumentary on everything "blasphemous". This isn't movie that'll teach you anything about occult and supernatural; this is the movie you should watch with your friends and have really good laugh.
P.S. Last part of the movie is about cryogenics. Guess that was occult in the 1970's.
