The Possession of Joel Delaney is a 1972 American horror film directed by Waris Hussein and starring Shirley MacLaine and Perry King. It is based on the 1970 novel of the same name by Ramona Stewart.
Due to a release during the early seventies and its dealing with the theme of possession, many reviewers compare it, some favorably, to The Exorcist, which would come one year later. The film was entered into the 22nd Berlin International Film Festival.
The Possession of Joel Delaney was the first film for Perry King and the last horror film Shirley MacLaine made.
