I'm still a sucker for the old Christmas specials (a relative who shall remain unnamed suggested that it was time to retire some of the older ones, but...no! I love the nostalgia of Rudolph the Red-nosed Reindeer). I suppose that we all have our favorites. Here's a video that pulls together clips from (mostly) more recent Christmas movies.
And here are some more traditional movies and specials.
So, what are your favorite Christmas movies or specials? I think mine is the Alastair Sim version of A Christmas Carol (originally titled Scrooge). But it was a difficult choice to make. There are so many that I enjoy watching again and again.
