No Christmas would be complete without "Its a Wonderful Life". Aside from being a truly wonderful movie it has a real Christmas "feel" to it (almost a Currier & Ives painting coming to film).

I agree with Sr. Vitelli that the best version of "A Christmas Carol" was the Alistair Sim version, and usually watch it once a year at holiday time.

The Bankin/Rass claymation version of "Rudolph the Red Nosed Reindeer" has been a favorite of mine for a long time and has been an annual tradition for at least ten years.
