Brain of Blood also known as The Creatures Revenge, The Oozing Skull, and The Undying Brain is a 1971 American horror film directed by Al Adamson and starring Grant Williams, Kent Taylor, and Reed Hadley. The film was shot in one go and is the only one of Hemisphere Productions films to be filmed in the United States. It was also Hadleys last film appearance before his death in 1972.
In 2007, Joel Hodgson created a new comedy riffing project called Cinematic Titanic. Along with other former cast members of Hodgsons former series, Mystery Science Theater 3000, Hodgson riffed Brain of Blood under the later DVD title The Oozing Skull as their first film for the new project.
