You have to watch Rear Window, you two! It's excellent. It's a great thriller - and it's really funny at the same time. One of the best introductions I could ever have had into the movies of Alfred Hitchcock.
Yes, I've heard of Disturbia, but because most movie remakes/adaptations/etc of classic Hollywood tends to be a bit... dodgy, I decided not to watch it. I mean, nobody replaces James Stewart. Especially not some 20 year old upstart who looks about 12 (no offense fans of Shia LaBeouf!).
