I've already mentioned that It's a Wonderful Life is my favorite Christmas movie. It's wonderful and heartwarming, and not only a favorite Christmas movie, but a favorite movie in general. Every life matters! :)
But there a few others I love. Jimmy Stewart was also in a short made for TV movie created by Brigham Young University and featuring the Mormon Tabernacle Choir called Mr. Krueger's Christmas. I love this charming little movie for its simplicity. Instead of being about big department stores and the latest hottest toy or trying to create the perfect Christmas--it's about an elderly lonely man who daydreams himself into many wonderful situations and its about the kindness of a child. But of course my favorite scene is when he imagines himself in the stable talking to Jesus. :)
And I also adore Holiday Inn. I love the concept of Holiday Inn first of all, but I also just really love the humor, dancing, and singing in this movie. I think I love it because I fell in love with it as a little girl watching late one night on a free channel on TV and so now I look forward to watching it each year.
I also like to watch some variation of A Christmas Carol each year. When I lived in St. Louis, we had a tradition to go with friends to see the stage play every year at the Fox Theater. How I miss those times! I used to love to walk into the Fox Theater and see it all festively decorated. And even though I know every bit of this story, I loved the musical production. I have many dear memories associated with those times. For the good ole TV, though, the George C. Scott version is my favorite. :)
I like a lot of the modern movies that have been made as well, like Elf, Christmas with the Kranks, The Family Stone, etc. But I do think these old classics that focus on the heart and spirit of giving and life with meaning are my favorites. (well Holiday Inn is kind of superficial, it's the exception!)
