IMDb plot summary: Mrs. Claus tells us about the time Santa had a bad cold and decided to take a vacation from Christmas.
Directed by Jules Bass and Arthur Rankin Jr. Starring Shirley Booth and Mickey Rooney.
This is cute and charming enough, and I suspect if I had grown up watching it I'd love it a bit more. The Snow Miser and Heat Miser characters are great fun, Santa is likable (if a bit emo), and even if it gets a bit heavy-handed with the "YOU MUST BELIEVE IN SANTA FOR CHRISTMAS TO WORK" message (gosh, I hate that one) it's pretty fun. 3 stars.
