Trivia: At the very end of the film the camera is zooming out with the observatory in the middle of the screen. Right before the credits begin, a man in a brown suit carrying a briefcase walks up to the observatory. This man is Nicholas Ray, the director of Rebel Without A Cause.
In the Police Station at the beginning of the film James Dean takes off his flecked jacket to reveal his spectacle case in his top pocket. As his character does not wear glasses the offending case is removed in the next scene.
