is a 1960 American psychological horror film directed and produced by Alfred Hitchcock
, and written by Joseph Stefano, starring Anthony Perkins, Janet Leigh, John Gavin, Vera Miles and Martin Balsam, and was based on the 1959 novel of the same name
by Robert Bloch. The film centers on the encounter between a secretary, Marion Crane (Leigh), who ends up at a secluded motel after stealing money from her employer, and the motel's disturbed owner-manager, Norman Bates (Perkins), and its aftermath.
After Hitchcock's death in 1980, Universal Studios began producing follow-ups: three sequels, a remake, a television film spin-off, and a prequel TV series. In 1992, the US Library of Congress deemed the film "culturally, historically, or aesthetically significant" and selected it for preservation in the National Film Registry.
