Who doesn't love the opening bank robbery scene in The Dark Knight? It's really an amazingly crafted sequence, and hey, it's Batman. I also love it when people overlay different music on movies and it just seems so...right. YouTube user Plan9Pics has paired the opening music from Hitchcock's Vertigo with the bank robbery scene and the end result feels nearly like whimsical and dark number from a stage play.
I think at certain points the music doesn't sync up nearly as well as the beginning, but it's still a pretty good match.
