In one of my favorite scenes in "127 Hours," in which James Franco plays Aron Ralston, who famously amputated an arm to rescue himself from Utah's Blue John Canyon, movie viewers are visually transported via flyover from the slot canyon where Franco/Ralston is trapped, back to his truck, where a left-behind bottle of Gatorade sits in the back.
Another scene shows him preparing for his trek from the point of view of a top shelf in his kitchen cabinet, his hand searching for a Swiss Army knife that he can't see and can't quite reach — and ultimately leaves behind. That sharp blade probably would have come in handy.
While I thoroughly enjoyed this movie, thinking about it makes me wince — and not just because of the graphic amputation scene, which I glimpsed between squinted eyes. It made me think of forgotten gear and food, and omitted destination notification.
