Lethal Weapon takes place around Christmas, the opening song to the movie is even Jingle Bell Rock.
Damn, beat me to it, that, and Die Hard. Love those movies, especially around Christmas. I love Christmas Vacation, thats probably my all time favorite.
Scrooged is good, with Bill Murray, not exactly your traditional Christmas movie, but it has the feel good vibe at the end.
Haha The Long Kiss Goodnight... That was actually a pretty good flick. I think if they had got someone besides Geena Davis, that would have been a better movie.
