Prom Night (film series)

Prom Night is a Canadian slasher media franchise consisting of five feature films, the first four of which are centered around events at the fictional Hamilton High School. The first film, Prom Night (1980), is a slasher film directed by Paul Lynch and produced by Peter R. Simpson, focusing on teenagers being stalked and murdered by a masked killer at their prom. The film was a box-office success, grossing nearly $15 million. The following sequel, Hello Mary Lou: Prom Night II (1987), was envisioned as a standalone film, but producer Simpson and his company, Simcom, refitted it as a sequel to the original Prom Night. Hello Mary Lou: Prom Night II, a supernatural-themed slasher film, introduced the character of Mary Lou Maloney, a vengeful young woman who died on her prom night in 1957; its only connection to the first film was that both films take place in the same high school.

In 1990, a second sequel featuring Mary Lou Maloney, Prom Night III: The Last Kiss, was released. The fourth film, Prom Night IV: Deliver Us from Evil (1992), featured an entirely new plot, following a group of teenagers tormented by a possessed Catholic priest on their prom night. In 2008, Screen Gems released a reboot mainly based on the original film, also titled Prom Night.
