White Christmas
How could I have forgotten? Shame on me. And there's also the earlier movie that served as a springboard for this one, Holiday Inn, which is where the song "White Christmas" came from. I prefer the first movie for one reason: along with Bing Crosby, it stars Fred Astaire. (Two of the most magical words in Hollywood to me.) Holiday Inn takes place all through the year; the concept is an inn that opens only for the holidays.
