Lady Possessed is a 1952 American mystery film directed by Roy Kellino and William Spier and starring James Mason, June Havoc and Stephen Dunne. Mason and his wife Pamela produced and wrote the film themselves, based on Pamela's novel Del Palma. They chose Pamela's ex-husband Roy Kellino, with whom she remained close, to direct the film. It was a critical and commercial failure, losing the Masons much of the money they had invested in it. The film's sets were designed by the art director Frank Arrigo.
