A Bucket of Blood tells the story of Walter Paisley (Dick Miller) who, after accidentally killing his landlady's cat and covering the body in plaster to hide the evidence, is acclaimed as a brilliant sculptor. Walter finds himself resorting to the same methods to produce new work, and soon people start mysteriously disappearing. Not wanting to direct another conventional horror flick, Roger Corman and screenwriter Charles B. Griffith came up with the concept for this entertaining black comedy about bad artists and the hypocrisy of the art world at large.
