Last night I watched The Eiger Sanction. It wasn't very good but I found one thing interesting.
The hero is Clint Eastwood. He's a macho mountain climber and killer but he's cautious. His character complains repeatedly that they shouldn't be using a route up a mountain that doesn't allow for an easy retreat.
The leader of the climb is arrogant, however, and dismisses Clint's concerns. He says that they won't need to retreat but (Spoiler Alert) bad weather comes, they do need to retreat and all the climbers die except Clint - who has to be saved by a team from the base.
The filming was actually done on a difficult climb. There were serious accidents and, ironically, a cameraman who fell and was hurt:
blamed Eastwood for the accident for lack of preparation, describing him as a director and actor as "a very impatient man who doesn't really plan his pictures or do any homework. He figures he can go right in and sail through these things"
