My favorites are:
- Christmas Vacation
Chevy Chase. Duh. What else needs to be said?
- The Grinch
Because Jim Carey is great in this movie! "Slunk!" And the costumes/sets are incredible.
- How The Grinch Stole Christmas (animated)
- Home Alone
- Its a Wonderful Life
"Buffalo gals won't you come home tonight, come home tonight, come home tonight. Buffalo gals won't you come home tonight, and dance by the light of the moon." Great story.
- The Year Without a Santa Clause / Rudolph the Red Nosed Reindeer (classics)
TYWASC was my favorite when I was little, though I think I like Rudolph more now.
- Elf
Because this movie is hilarious. "Buddy the Elf, whats your favorite color?" Plus, they do a great job of mixing in references from the old Christmas movies.
- Miracle on 34th Street (the newer one)
- Jingle All The Way
because of this line, "Who told you you could touch MY cookies?! Put those cookies DOWNNN! NOW!" - Arnold
