With good reason. This movie truly does have it all. Romance, drama, wit, class, and even a slight (or not-so-slight) dash of murder. If you like either Bogart, Bergman, or any of the excellent supporting cast, you've simply got to see Casablanca. It really is too bad about the lines, because most people under 20 are just bound to think they "ripped it off" of other films. Patience, patience... ; )
