Directed by Miloš Forman | Starring: Jack Nicholson, Danny DeVito, Christopher Lloyd, Brad Dourif
A petty criminal fakes insanity to serve his sentence in a mental ward rather than prison. He soon finds himself as a leader to the other patients—and an enemy to the cruel, domineering nurse who runs the ward.
