Blood Bath is a 1966 American horror film directed by Jack Hill and Stephanie Rothman and starring William Campbell, Linda Saunders, Marissa Mathes, and Sid Haig. The film concerns a mad painter of weird art who turns into a vampire-like man (with different features) by night, apparently as a result of a family curse, and believes that he has found his reincarnated mistress in the person of an avant-garde ballerina.
