Perfect movie to show if you want to explain to people the concept of leitmotif. All of the main characters have specific themes that are heard when they are on the screen, and the manner in which two of the themes sometimes seem interchangeable with two of the characters actually telegraphs musically their relationship long before it is revealed in the film. A great example of how much a score can bring to a film.
