Could you suggest a scene from a movie that doesn't have music in it, but might work with music? I know there's The Birds, but I don't think music would work for that particular scene at all because of what Hitchcock's vision was.
Some ideas that I`ve gotten so far:
-Boxing Scenes from Bull Durham
-No Country for Old Men (too recent for YouTube)
-Jury room scenes from 12 Angry Men
-Speedbike chase from Return of the Jedi
Try "The French Connection" very little music...
