When this movie first came out, we went to the theater to see it. What a riot! I laughed so hard and still do everytime I watch it, which has been quite a few times! It's one of my favorites!
This film is a 1989 Christmas comedy starring Chevy Chase who just wants to have a "good old fashioned family Christmas." It turns out to be anything but that!! What a holiday classic!
