Nothing tops "How the Grinch Stole Christmas". Not only is it the best movie, but it also has the best Christmas song as well.
It also provides some wonderful, year-round insults like, "Your soul is an appalling dump heap overflowing with the most disgraceful
assortment of rubbish imaginable, mangled up in tangled up knots!"
While not my favorite,Elfis a rather enjoyable movie. It's directed by Jon Favreau (Iron Man) and Peter "Tyrion" Dinklage plays a small (heh) role in the movie.
I also have to give a mention to Trading Places. It's not about Christmas per se, but takes place at the time.
Do yourselves a favor and just watch this! Eddie!!
