Halloween is a 1978 American independent horror film directed, produced, and scored by John Carpenter, co-written with Debra Hill, and starring Donald Pleasence and Jamie Lee Curtis in her film debut. It is the first installment in the Halloween franchise. The film is set in the fictional midwestern town of Haddonfield, Illinois. On Halloween 1963, six year old Michael Myers murders his older sister by stabbing her with a kitchen knife. Fifteen years later, he escapes from a psychiatric hospital, returns home, and stalks teenager 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 $320,000 and grossed $47 million at the box office in the United States, and $70 million worldwide, equivalent to over $234 million as of 2012, 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 clichés found in low-budget horror films of the 1980s and 1990s.
