Scary Movie is a 2000 American satirical horror comedy film directed by Keenen Ivory Wayans. The film is a dark comedy that heavily parodies the horror, slasher, and mystery genres. Several mid- and late-'90s films and TV shows are spoofed, primarily Scream and I Know What You Did Last Summer, as well as Buffy the Vampire Slayer, The Sixth Sense, The Usual Suspects, The Matrix, The Blair Witch Project, and Dawson's Creek.
The film was originally titled "Last Summer I Screamed Because Halloween Fell on Friday the 13th". The title was changed to Scary Movie in homage to the production title of Scream, which was also released through Dimension Films, and which serves as the primary inspiration for the film.
