Prom Night is a 1980 Canadian horror film directed by Paul Lynch, based on a story by Robert Guza, Jr., and starring Leslie Nielsen and Jamie Lee Curtis. The story concerns a group of high school seniors who are targeted by a mysterious killer in revenge for their culpability in the accidental death of a young girl six years earlier. The anniversary of the incident falls on their high school's prom night, when the older sister of the dead girl is being crowned Prom Queen.
Filmed in Toronto in late 1979 on a modest budget, Prom Night was considerably popular upon its release, especially within the drive-in theater circuit. Despite receiving generally negative reviews from critics, the film was a massive financial success, becoming Canada's highest-grossing horror film of 1980. It also received Genie Award nominations for editing and for Curtis's performance.
