OK here are a few great cold war movies:

"Ice station Zebra." It doesn't get colder than the north pole.

"A midnight Clear" Winter in Germany WWII. Inadequate clothing compounded by hunger, fatigue. Pretty chilly.

"The Pianist" Although parts of the movie took place in the summer there was a scene towards the end where it was winter and the hero was hiding in an unheated abandonded house. I'd say it was cold–ish.

There was also a movie with Lee Marvin and a lot of snow I think it was the Korean war, I can't remember the title.

There was also "gorky park" with a super–annuated lee marvin, most of which revolved around skating and other winter time activities, but that wasn't really during a war so much as during that period of tension between the US and Soviet Russia before the wall came down.
