Vanilla Sky? Changed your life? That's kind of an odd choice. I'm not saying that it's a bad movie. I was just expecting you to say something like "The Godfather" or "The Matrix" or something considered to be a little more... great...

My 2 cents about a movie that changed my life - "Eyes Without a Face." It's an old black and white movie that I saw about 4 months ago, but it is one of the coolest / creepiest movies I've ever seen...
