Danny DeVito was featured alongside Jack Nicholson in the 1975 film One Flew Over the Cuckoo's Nest. The film was directed by Miloš Forman and based on the novel of the same name by Ken Kesey. It tells the story of Randle Patrick McMurphy (Nicholson), a criminal who feigns insanity to avoid prison and is sent to a mental institution. There, he clashes with the authoritarian Nurse Ratched (Louise Fletcher).
