In this 1975 classic directed by Miloš Forman, a rebellious inmate named Randle McMurphy, played by Jack Nicholson, feigns insanity to serve his sentence in a mental institution rather than a prison. Inside, he encounters the oppressive Nurse Ratched, portrayed by Louise Fletcher, and becomes a catalyst for change among the patients. The film explores themes of individuality and authority, set against the backdrop of a mental health facility. It won five Academy Awards, including Best Picture, Best Director, and acting awards for both Nicholson and Fletcher. For those interested, the movie can be viewed for free on 123Movies / Movies123.
