One Flew Over the Cuckoo’s Nest:

The viewer is taken into the environs of a mental hospital in this 1975 movie. It delves into the life of a man called Randall McMurphy, a convict who chooses to spend time in the hospital, rather than serve time in prison. He achieves this by feigning to be slightly crazy. The time he spends in the mental ward, the interactions he has with the other patients there, his conflicts with the insensitive and cold nurse, named Ratched, are what make this one of the best Hollywood movies. The movie went on to sweep all the major Oscar awards of that year, such as Best Actress, Best Actor, Best Screenplay, Best Director, and Best Picture. Its star cast includes Jack Nicholson, Danny Devito, Louise Fletcher, William Redfield, Peter Brocco, Michael Berryman, and Alonzo Brown.
