One Flew Over the Cuckoo's Nest is a 1975 American comedy-drama film directed by Miloš Forman, based on the 1962 novel One Flew Over the Cuckoo's Nest by Ken Kesey. The film stars Jack Nicholson and features a supporting cast of Louise Fletcher, William Redfield, Will Sampson, and Brad Dourif.
Considered to be one of the greatest films ever made, One Flew Over the Cuckoo's Nest is No. 33 on the American Film Institute's 100 Years... 100 Movies list. The film was the second to win all five major Academy Awards (Best Picture, Actor in Lead Role, Actress in Lead Role, Director, and Screenplay) following It Happened One Night in 1934, an accomplishment not repeated until 1991 by The Silence of the Lambs. It also won numerous Golden Globe and BAFTA Awards.
In 1993, the film was deemed "culturally, historically, or aesthetically significant" by the United States Library of Congress and selected for preservation in the National Film Registry.
