Peter Cushing – Christopher Lee 1965
A disreputable fence offers Christopher Maitland, a professor of occultic studies, a skull, which is reputedly that of the Marquis de Sade. A fellow collector who once owned the skull warns Maitland that de Sade was possessed by an evil spirit. The spirit still inhabits the skull and emerges on the two nights of the new moon, the traditional nights of witchcraft and Devil worship. And when the new moon arrives, Maitland finds himself being possessed and driven to acts of murder by the skull as it comes to life. Much too soon he discovers how the skull affects him: by turning him into a frenzied killer.
