I always liked the scene in Unbreakable from where Bruce Willis' character is standing in the mall, to after he rescues the family in that house. I can't explain it in words, because I suck at words, but I think it's a very powerful scene. I love it and rewatch the movie just for that one part. Although it helps that the rest of the movie is just as good. :D

There are loads of things from Constantine too. The bathtub scene, when he meets the Devil. :( The whole damn thing.
