Yes! And the supplemental material includes a documentary that they shot when the entire crew and all three principals went back to the mountain for shooting. Joe, the guy who fell, talks about how he's come to peace with the whole thing, but he starts to get weirded out by being there. Simon, the guy who cut the rope, keeps denying that any of it effected him--this was just one climb of many, etc.--but it's clear that he's not real happy about being known forever as, well, "The Guy Who Cut the Rope." It's a fascinating documentary and basically stands as the next 45 minutes or so of the original movie.
The other thing I didn't realize was that Joe played himself in some of the long shots of crawling off that glacier and through that moraine. Being forced (or at least contractually obliged) to repeat that is at least part of why Joe stops being so happy to be back.
Googled it right after your post correcting me. I'm going to have to get a copy because it was a fascinating documentary, and the footage of the crevasse (sorry about my crevice blunder) was really effective and powerful. Simpson's (he was the guy that was left, right?) climb down that mountain is the stuff of legends, only it's true. I wouldn't want to be the 'rope cutter' that's for sure. But I have to say that I really didn't judge the guy too harshly myself when I first saw the piece because it didn't seem he had much of a choice. I don't see how he could have helped Simpson, really, and if he hadn't cut the rope he might have caused the both of them to die. What do you think his chances of saving the both of them would have been should he have stuck around?
