The Thing (1982)
Baby, it's cold outside: The coldest of all cold horror movies, The Thing sees a group of researchers trapped in a facility in the Antarctic, pursued by an insidious creature from another world that can perfectly mimic human form. Shiver.
Chill factor: 10/10
As cosy as Kurt Russell looks in his big furry coat, he's gonna need a lot more protection than that to deal with what's waiting for him in the snow.
