Wikipedia: Rebel Without a Cause
Rebel Without a Cause is a 1955 American drama film about emotionally confused suburban, middle-class teenagers filmed in CinemaScope. Directed by Nicholas Ray, it offered both social commentary and an alternative to previous films depicting delinquents in urban slum environments. The film stars James Dean, Sal Mineo and Natalie Wood.
 
The film was a groundbreaking attempt to portray the moral decay of American youth, critique parental style, and explore the differences and conflicts between generations. The title was adopted from psychiatrist Robert M. Lindner’s 1944 book, Rebel Without a Cause: The Hypnoanalysis of a Criminal Psychopath. The film, however, does not make any references to Lindner’s book in any way. Warner Bros. released the film on October 27, 1955.
