My favourite ALL TIME movie is "One Magic Christmas"

It's not well known but it's SOOOO GOOOD!! If you haven't seen it, go rent it. It has Mary Steenbergen in it.

Other favourite Christmas movies are:
Muppet Christmas Carol (I like that version better than any other one :P)
Prancer
The original Rudolph and Frosty's
and the most recent one to add to the list.. The Polar Express
