My all time favorite Christmas movie is White Christmas. Lovely film, beautifully produced. Watching it is like having an old friend visit, and I san sing along with every number in it. Absolutely fabulous movie, and I'm a big Danny Kaye and Bingle fan.
Also watched The Christmas Chronicles on Netflix - a very fun movie, and a nice take on Christmas. Kurt Russell also does a killer Santa blues number in jail. with Stevie Van Zandt on guitar. Recommended for fun.
My daughters vote for Die Hard as a Christmas movie (a subject of some controversy today) but although I like the movie, I'd just as soon stay with something kindler and gentler on Christmas.
