The Black Room

The Black Room is a 1982 American horror film directed by Elly Kenner and written and co-directed by Norman Thaddeus Vane. It stars Stephen Knight, Cassandra Gava, Jimmy Stathis and Clara Perryman, and features Christopher McDonald and Linnea Quigley in small, early roles. The plot concerns siblings who lure swingers to their Hollywood mansion, kill them, then - with long scenes of blood transfusions - drain their blood. Though there is no classical vampirism in the film --in the sense of supernatural beings or blood drinking-- the plot's focus on draining blood to prolong life has led to many sources considering it a vampire film.
