The Stepfather
This film has one and only one star: Terry O'Quinn. Throughout the film, he delivers a haunting performance as the titular stepfather.
His shining moment is when he makes the opening sequence into the memorable scary scene that it still is with his calm demeanor after a horrible deed. Whenever I see this film, I can't help but wonder: Was the idea of Jerry Blake whistling Camptown Races already in the script or did O'Quinn improvise that?
