One Flew Over the Cuckoo's Nest is a 1975 American drama film directed by Miloš Forman, based on Ken Kesey's 1962 novel. Jack Nicholson stars as Randle Patrick McMurphy, a charming, rebellious criminal who feigns mental illness to serve his sentence in a psychiatric hospital rather than a prison work farm. Once inside, McMurphy disrupts the ward's repressive order maintained by the tyrannical Nurse Ratched, played by Louise Fletcher, encouraging the other patients — including the enormous, seemingly mute Chief Bromden played by Will Sampson — to assert their individuality and challenge the institution's dehumanizing control.

One Flew Over the Cuckoo's Nest became only the second film in history to win all five major Academy Awards — Best Picture, Best Director, Best Actor, Best Actress, and Best Adapted Screenplay — a feat previously accomplished only by It Happened One Night in 1934. Jack Nicholson's McMurphy remains one of the most charismatic and beloved performances in cinema, his anarchic energy and genuine compassion for the other patients creating a character who embodied the counterculture's resistance to institutional authority. Louise Fletcher's Nurse Ratched was equally iconic as the face of bureaucratic cruelty — her calm, pleasant demeanor masking an absolute commitment to control that made her more frightening than any overt villain.

The film earned $108 million worldwide on a $4.4 million budget. Its influence on how popular culture depicts mental health institutions, patient rights, and the conflict between individual freedom and institutional control has been profound and enduring.
