Halloween is a 1978 American independent slasher film directed and scored by John Carpenter, co-written with producer Debra Hill, and starring Donald Pleasence and Jamie Lee Curtis in her film debut. The film was the first installment in what has become the Halloween franchise. The plot is set in the fictional Midwestern town of Haddonfield, Illinois. On Halloween night in 1963, a six-year-old Michael Myers dressed in a clown costume murders his older sister by stabbing her with a kitchen knife. Fifteen years later, Michael Myers, age 21, escapes from a psychiatric hospital, returns home, and stalks Laurie Strode and her friends. Michael's psychiatrist Dr. Sam Loomis suspects Michael's intentions, and follows him to Haddonfield to try to prevent him from killing.
Halloween was produced on a budget of $300,000 and grossed $47 million at the box office in the United States, and $70 million worldwide, equivalent to $250 million as of 2014, becoming one of the most profitable independent films. Many critics credit the film as the first in a long line of slasher films inspired by Alfred Hitchcock's Psycho (1960). Halloween had many imitators and originated several cliches found in low-budget horror films of the 1980s and 1990s. Unlike many of its imitators, Halloween contains little graphic violence and gore. In 2006, it was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant".
