Demoniac originally went out as Ripper of Notre Dame. Director Jess Franco, discreetly avoiding his given name of Jesus Franco, plays the title role. He's fun to watch in a disgusting sort of way, but the production values and supporting cast don't come up to his admittedly unexacting standards. Lots of slashing, lots of nudity, little sense-but you probably guessed that when you read the title. The film also exists in a hard-core pornographic version titled Exorcism and Black Masses, available at off-brand video rental shops.
