Got in a viewing of this classic on Dec 25th. It's made for TV, so it's low budget in many ways, but they managed to get George C. Scott, David Warner, Edward Woodward, and Susannah York. The music is over-dramatic at times and sometimes the sets look like a stage play, and it often seems the director is more used to directing for stage than television, but George C. Scott is just killin' it so hard that little things like that are easy to overlook.
Easily my favorite Christmas movie. 10/10
Oooh... whole thing on YouTube
