Also, Val Lewton's "Curse of the Cat People" is a wonderful Christmas movie -- Really, check it out!

I dearly love that film - it's one of my favorites. The Christmas-themed scene where Simone Simon sings the Serbian carol in counterpoint to the carolers is particularly memorable.
DEAD OF NIGHT (1945) has a rather creepy traditional English Christmas ghost episode concerning a game of hide-and-seek, a secret room, and a sad little boy.
