Hello Mary Lou: Prom Night II

Hello Mary Lou: Prom Night II is a 1987 Canadian supernatural slasher film directed by Bruce Pittman, and starring Michael Ironside, Wendy Lyon, Louis Ferreira, and Lisa Schrage. It follows a high school student who becomes possessed by Mary Lou Maloney, a student who died at her high school prom in 1957. A sequel to the slasher film Prom Night (1980), it was originally intended to be a standalone film titled The Haunting of Hamilton High, but was retitled in order to capitalize on the success of the original Prom Night. The only connection between the two films, that the high schools where the films are set have the same name, was a complete coincidence.
