Fa la la la la ...

Because I know it's the burning question on everyone's mind, my favorite Christmas song is O Holy Night - I think the lyrics are so beautiful. Coming in at a close second is Carol of the Bells, because the music and the harmonies are gorgeous. Guess what is third?

Well, it's the quasi-Christmas song, Last Christmas by Wham!, obviously.

I have a question, though. Last Christmas was in a movie, and neither Scott nor I can remember which one. The Internet doesn't know, either, although it does puzzle at Last Christmas' curious popularity. So I need your help, y'all. What's the movie? It will drive me even crazier than I already am until I figure it out. Any help will be appreciated.
