Let's have a scifi/horror Christmas!

Until I read a blurb on in-demand today, I’d forgotten that the horror movie Dead End takes place on Christmas Eve.

I’d like to make a list of less-obvious (meaning doesn’t have the words “Christmas” or “Santa” in the title) movies set on Christmas Day or Christmas Eve. You can list the obvious ones too, but I’m more interested in the less obvious ones.

So to start off:
Dead End
Gremlins
uh, someone want to help me out, here? :smiley:

Black Christmas
Silent Night, Deadly Night
Silent Night, Bloody Night
