oh boy, I could come up with a large list here. I don't watch them all every year as there is just too many. I alternate.
Movies:
A Christmas Carol(Alastair Sim, George C. Scott, and Patrick Steward versions, I may have to day the new animated Disney version. I don't like the added action scenes, but even with them, it is one of more accurate versions I've seen)
Scrooge(the Musical starring Albert Finney)
(yes, I am a big fan of the story A Christmas Carol. I highly recommend that everyone should really the Book. I try to read it every year as this time.)
Miracle On 34th Street(the original)
Its A Wonderful Life
The Lemon Drop Kid(its where the song Silver Bells comes from)
White Christmas(I have a tradition of watch this one at midnight on Thanksgiving to officially start the Christmas season. )
The Bishop's Wife
It Happened on Fifth Avenue
Die Hard's 1 and 2
(at some point, I intend to get "The Nativity Story" and add that to the list)
TV specials:
Rudolf The Red Nosed Reindeer
Frosty The Snowman
The Grinch Who Stole Christmas
Santa Claus is Coming to Town.
Twas The Night Before Christmas.
A Chipmunk Christmas
If I could, I'd like to get a hold of the original Looney Tunes and Disney Christmas specials that aired when I was a kid.
I could probably add more to the list, but that is enough for now.
