A while back there was a thread where you could ask questions that were bugging you in the hope it would jog the memory of someone on this blog who could help out by providing the answer.

The title of a particular film has been driving me nuts for thirty years or more. It's probably the first film I ever saw and I remember it very vividly (I think) and I would love to see it again but have no idea what it might be called. I saw it on TV so can't even guess when it was made, the closest I can estimate is it probably came out prior to 1970.

The climax as I remember it... (spoiler alert!)

There are two mountain climbers, one young and cocky, the other older and cautious. They are climbing a mountain and as they approach the peak they are faced with a valley criss-crossed with ice-bridges and there is no other way across. Only the older one can tell which bridge is strong enough to hold their weight.

He picks the right one, they reach the peak. Coming down again they come to the same spot. Having conquered the mountain the now over-confident young one rushes ahead to an ice bridge and begins to cross. The older one warns him that it's not the right bridge. The young one ignores him and plummets to his death. The end.

My question is this, what frigging film is this?

The only other clue I have is it might have been produced by Paramount as I seem to remember the last shot was of the mountain that dissolved into a logo of a mountain which whould make it Paramount. However I may have misremembered that.

Thank you for reading this far and God bless you if you can help!
