Warlock Moon (1973)
aka Bloody Spa. Joe Spano (Hill Street Blues) and Laurie Walters (Eight is Enough) are a young couple on a nice country drive when they happen across the remains of an old abandoned health spa. While exploring, they come across an elderly couple still living in the ruins. They tell the youngsters the story of the place; how it was the headquarters to a Satanic cult who preformed cannibalistic rituals on unsuspecting visitors. Then they invite them to stay for dinner… The DVD includes an introduction and commentary by Joe Bob Briggs, original trailer, and alternate opening sequence. Out of print DVD.
