Black Sabbath (Italian: I tre volti della paura) is a 1963 Italian-French horror film directed by Mario Bava. The film is centered on three separate tales that have an introduction and conclusion from Boris Karloff. The film stars an international cast in three short stories. The first, titled "The Telephone", involves Suzy (Michèle Mercier) who continually receives threatening telephone calls from an unseen stalker. The second is "The Wurdulak", where a man named Gorca (Karloff) returns to his family after claiming to have slain a Wurdulak, an undead creature who attacks those that it had once loved. The third story, "The Drop of Water", features Jacqueline Pierreux as Helen Corey who steals a ring from a corpse that is being prepared for burial and finds herself haunted by the ring's original owner after arriving home.
