Diary of a Madman

“The most terrifying motion picture ever!”

Simon Cordier (Vincent Price), a French magistrate who sculpts in his spare hours, begins to sense an invisible presence in his house that no one else can see. Reginald Le Borg gives this being, called the horla, enough force to move objects and, worse, to take hold of a person's mind. The film's fear is that your own will can be borrowed, and nobody around you would be able to tell.
