The Caller is a 1987 mystery thriller film starring Malcolm McDowell and Madolyn Smith, distributed independently by Empire Pictures. The film appears at first to be a straightforward story about a man wanting to use a girl's telephone, but things aren't as they seem. Similar to a stage play, it is set in a primary location with only two actors. The film was shot in the Lazio region of Italy.

Special effects were supervised by John Carl Buechler, known for his long list of film credits including Friday the 13th Part VII: The New Blood, A Nightmare on Elm Street 4: The Dream Master, and Re-Animator.
