Christmas Story, of course. Adult Swim on Cartoon Network at 11 PM had X-Mas episodes of Futurama and Family Guy...those were. Especially with the baby on Family Guy (not a show I normally watch but will now) calling Santa Claus "Klaus" like "Klaus von Bullow" like some James Bond villian. Sweet.
At some point during my Christmas holiday at home with family, we all watch "A Christmas Carol" (the George C. Scott version), "Rudolph, the Red-Nosed Reindeer" (the Claymation version with Burl Ives et al), and "The Nutcracker" (which, being a filmic adaptation of the ballet, isn't strictly speaking a movie...but is great all the same. It's the one with Mikhail Baryshnikov in the title role).
The George C. Scott version of "A Christmas Carol" is my all-time favorite Christmas film. I think it is perfect.
