Movie: I don't have any number one favorite movie. I have movies that if it's a Sunday afternoon and they're on TV, I drop everything. One is Groundhog Day. Others are Aliens, Air Force One. My favorite Christmas movie? Die Hard. I have movies for every occasion, but I don't have any favorite movie.
