The 1970 documentary Satanis: The Devil’s Mass is a goofy, occasionally fascinating, exploitation flick that takes us “behind the scenes” of Anton LaVey’s Church of Satan. It’s all rather silly and even though it contains plenty of nudity the overall effect is about as sexy as watching snails copulate.

The interviews with LaVey’s neighbors and followers are often hilarious. And LaVey oozes all of the smarmy charm of a used car salesman in a 5 dollar Halloween costume. This is sinema verite for the raincoat crowd.

NSFW unless you’re working in the anteroom of a cathedral in Hell.
