The movie was pretty close, but the climbing scenes were filmed off the real climbing route, below a ledge on the north side where I spent the night. I will try to find a photo.
OK, the descent route is in red and the ledge about halfway down is where the climbing scenes in Eiger Sanction were filmed, hanging over the north face. One person was killed by a falling rock there while filming. The place the huge avalanche happened was lower than this ledge and off the right of this photo. OK you can see the hanging glacier on the right in this photo. 
Impressive climbing history. I have never met anyone personally that has wanted to do a repeat of the Eiger.
My climbing has always been in the Rockies. Never the time or budget for the big mountains or Europe.
I will be in Ouray area Jan- Feb., and back out in April- May for spring alpine.
Shoot me a PM if in the area. Like to buy you a beer.
