A big Oscar winner in 1975, One Flew Over the Cuckoo's Nest still holds up remarkably well. Ken Kesey's novel, an allegory of repression and rebellion set in a mental hospital in the early 1960s, is cannily adapted by Czech director Milos Forman into a comedy drama with a cool, unassuming, near-documentary look. Jack Nicholson has his most jacknicholsonian role as Randle P McMurphy, a livewire troublemaker who unwisely cons his way out of prison and into a mental institution without realising he has switched from serving a sentence with a release date to being committed until adjudged sane by the same people he is winding up on a daily basis. Louise Fletcher, in a career-defining turn, is Nurse Ratched, the soft-spoken sadist who represents the worst type of matronly authoritarianism and clashes with Randle all down the line.
