Blood of the Vampire is a 1958 British colour horror film directed by Henry Cass from a screenplay by Jimmy Sangster and produced by Robert S. Baker and Monty Berman's uncredited Tempean Films. The film stars Donald Wolfit, Barbara Shelley and Vincent Ball. Its plot involves a scientist who uses the inmates of a Prison for the Criminal Insane in Transylvania as sources for his gruesome blood-typing and -transfusion experiments that keep him alive.
Many fans thought the film was a Hammer Film when it came out, due to its similar look and Sangster's writer's credit. The film was released on a double bill with Universal's Monster on the Campus in October 1958.
