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.
In 1963 Oregon, Randle Patrick “Mac” McMurphy (Jack Nicholson), a recidivist anti-authoritarian criminal serving a short sentence on a prison farm for the statutory rape of a 15-year-old girl, is transferred to a mental institution for evaluation. Although he does not show any overt signs of mental illness, he hopes to avoid hard labor and serve the rest of his sentence in a more relaxed hospital environment.
