If you're not really too set on the holiday theme, I would also highly recommend:
Crows Zero and Crows Zero 2

and the hongkong young and dangerous series.

I think people should buy up the rights and all the copies and have a good old fashioned movie burning.

If I were a jackass, I would suggest Silent Night, Deadly Night Part 2. But I'm not, so instead, I'll just link to the only memorable part of that movie.

Jingle All The Way. Gotta watch at least once. :)

These are all great choices for films that take place during Christmas.

Except maybe for Brazil?

I had always thought that it wasn't that Brazil took place during Christmas, but rather that in the world of Brazil, there was never a time that wasn't Christmas.

Anyone else read it that way?

I've heard of and liked all of those movies besides Brazil. I've never even heard about it before. I'm guessing that it is this one your talking about http://www.imdb.com/title/tt0088846/ but I am not really sure.

Brazil is a great movie, but it's a Terry Gilliam film, so you have to be prepared for his kind of weirdness.

I think he did Fear and Loathing in Los Vegas which was weird but pretty good, but weird movies don't really bug me very much after my David Lynch phase.

To anyone considering watching Brazil...in addition to preparing yourself mentally for Gilliam weirdness, you also need to make 100% sure that you watch the director's cut. Do NOT watch the "Love Conquers All" version (or the theatrical version). The Love Conquers All version was sabotaged by the studio to intentionally make the film suck. Watch the director's cut, which is edited properly and how the director intended the movie to be seen.
