Film Snowy Survival (and/or Adventure) Films

I'm trying to put together a list of survival/adventure type films that take place in cold and snowy environments. Basically films in which people are fighting against the cold/snowy elements and have to struggle to survive. I think I've seen most of them but I'm hoping others can add to the list and maybe I will find movies I haven't seen.

I will list what I can remember having seen already, and I'll edit this post if you would be kind enough to add other films. It can include fictions or documentary style films and re-enactments, etc.

-Vertical Limit
-The Grey
-Everest
-Touching the Void
-The Summit

you are misusing prefixes.

-The Revenant
