Halloween is a 1978 horror film directed by John Carpenter. It's recognized as one of the seminal films in the slasher genre. The film tells the story of Michael Myers, who was committed to an insane asylum as a kid after murdering his sister on Halloween night. 15 years later, Myers escapes and goes back to his hometown of Haddonfield, Illinois, where he targets a group of teenagers, including Laurie Strode (played by Jamie Lee Curtis in her film debut). The cast also includes Donald Pleasence, P.J. Soles, and Nancy Loomis. The movie is notable for its eerie musical score composed by Carpenter himself and for establishing many conventions of the slasher genre. Its success led to a long series of sequels and reboots, and Michael Myers has since become one of the most iconic characters in horror cinema history.
