The inspiration for "One Flew Over the Cuckoo's Nest" came while working on the night shift with Gordon Lish at the Menlo Park Veterans' Hospital. There, Kesey often spent time talking to the patients, sometimes under the influence of the hallucinogenic drugs he had volunteered to experiment with. Kesey did not believe that these patients were insane, but rather that society had pushed them out because they did not fit the conventional ideas of how people were supposed to act and behave. Published under the guidance of Cowley in 1962, the novel was an immediate success; in 1963, it was adapted into a successful stage play by Dale Wasserman, and in 1975, Miloš Forman directed a screen adaptation, which won the "Big Five" Academy Awards: Best Picture, Best Actor (Jack Nicholson), Best Actress (Louise Fletcher), Best Director (Forman) and Best Adapted Screenplay (Lawrence Hauben and Bo Goldman).
