In all seriousness, it's a charming film about a hairbrained business scheme--an inn and nightclub that's only open on holidays. Between Bing's chocolate-smooth singing voice and Fred Astaire cutting a rug (and providing one of the best-choreographed inebriated scenes in film), it's pure Golden Age entertainment from the first frame to the last. Watch for the straight-up WWII propaganda midfilm.
You know what's fun at Christmas? Nuns, that's what. The Bells of Saint Mary's was released as a Christmas film. I don't know if Come to the Stable was or not, but the live nativity scene opener would indicate so. Regardless. Nuns having fun. Enjoy.
OK, here's one I thought I'd never see. Yes, Santa and Satan, together at last.
So leave the holly out a few more days, and curl up with a new old movie!
