127 Hours.
I've watched 3 different films today. I really liked this one. Not a lot happened, over 1 hour was filmed in one place, as to be expected really. It sort of had a Phone Booth feel to it in that sense. I thought the way they shot what he was seeing/feeling well and, at some points, really clever. They also got the camcorder scenes really accurate to the actual Aron Ralston footage.
