I too, love Christmas movies.
#1 - Christmas Carol but the ones with Scrooge himself (Alistair Sims, Reginald Owens, Patrick Stewart, George C Scott etc). Even the Flintstones, Muppets. It's gotta be a SCROOGE.
#2 - the Christmas Carol-themed stories (with other actors like Vanessa Williams, Susan Lucci, Bill Murray, etc) These have main characters with a different name.
#3 - the classic Charlie Brown Christmas Tree cartoon tied with the cartoon Grinch.
#4 - Miracle on 34th Street, White Christmas, Wonderful Life and Bishop's Wife all tied in here.
#5 - the classic 1960's Rankin & Bass cartoons, ie Rudolph, Frosty, etc.
But I think I'm falling in love with Elf with Will Farrell. Have watched it 3 times in 2 days. I laugh myself silly. And I'm by myself, no kids, and laughing OUT LOUD. I think the antics are hysterical.
There's other Christmas-themed movies out there,, but these are my favs. And they're the old ones. If I'm flipping channels, I stop to watch.
With the exception of my #2 listing above, I have my own VCR copies of all these. Don't have just one fav, I love them all!!!
