Stage Fright () is a 1987 Italian slasher film directed by Michael Soavi, and starring Barbara Cupisti, David Brandon, and Giovanni Lombardo Radice. The plot involves a group of stage actors and crew who lock themselves inside a theater for rehearsal of a musical production, unaware that an escaped mental patient is locked inside with them. Plot Late at night, inside a theater, a troupe of actors and crew consisting of the director Peter, Alicia, Mark, Sybil, Betty, Corinne, Laurel, Danny, Brett, and Ferrari are rehearsing a musical about a fictional mass murderer known as the Night Owl. Peter is very dominating over the group and tries to keep them from leaving under any circumstances without his permission.
