The US flag appears in One Flew Over the Cuckoo's Nest 1975. During a field trip when all the patients are on a bus, the US Flag can be seen flapping in the background. The film stars Jack Nicholson as a troubled person in the psychiatric ward.
Top notch acting, directing and storytelling gives this film a lasting impact in the league of the Wizard of Oz 1939. Of a wholly different theme, yet qualifies as a timeless story, that tells of the human drama of control vs. freedom.
