Man this was deep. Guy goes hiking, he falls down a crevice and a rock pins his hand to the cave wall and is stuck for 5 days. The first 2 days is him trying to get his hand unstuck and rationing his food and water. He flirts with the idea of having to cut off his arm. He made a video diary with the camcorder that he carried with him. The scene where he cut his arm off was more grusome then any horror movie I've because it was something that really happened and the fear and pain and agony was beautifully bought out in the film. James Franco did an excellent job playing this role. This is in the same vein as Castaway, one actor pretty much carrying the movie, but it was great story of survival.
