The story of how Santa Claus came to be is brought to life through the magic of stop-motion animation in this Christmas-themed production for the family. A friendly postman (voiced by Fred Astaire) explains how friendly Kris Kringle (voice of Mickey Rooney), a foundling taken in by a family of toymakers, took it upon himself to bring some happiness to the children of Sombertown, despite the grumpy opposition of Burgermeister Meisterburger (voice of Paul Frees) and the Winter Warlock (voice of Keenan Wynn). Santa Claus Is Comin To Town was directed and produced by Jules Bass and Arthur Rankin Jr., who created another popular animated story of the season, Rudolph The Red Nosed Reindeer. ~ Mark Deming, All Movie Guide
