Here's a video with the shower scenes from Hitchcock's Psycho and Van Sant's shot-for-shot re-shoot of it transparently overlayed on each other. (I never sat all the way through the Van Sant version, because, wow, what a total waste of time.)
Scene missing! A video that used to be embedded in this post has disappeared. If you know of a copy of this video that is still accessible, please mail me so that I can update the link.
