Last year a week before christmas I watched the colourized, HD version of It's a wonderful life because I had never seen it and it is considered one of the American Christmas classics. I really loved it but was surprised how little it had to do with Christmas. I think only the last 10% of the film was set during Christmas when he was with the guardian angel and everything. The rest of it though was really amazing. The story and character development was brilliant.
(BTW, is anybody else sick to death of Jingle Bells? I hate that song with a passion.)
