Non-guitar players might say "The Crow", but I wouldn't. Nothing impressive playing wise there, but I guess it fit the movie.

On a somewhat related note, there's a movie called "The Red Violin" which has some awesome playing there. Sure it's not a guitar, but seeing that movie made me wish I could play my guitar at the same level they played those strings. Pretty good movie too...a violin maker puts all his love and effort into one particular last instrument, and every player who inherits it throughout history displays skill like they're possessed. I saw it years ago, and it might even be subtitled in parts (I don't remember), but it's an independent, like a Sundance movie or something.
