An animated adaptation of A Christmas Carol from Arthur Rankin Jr. and Jules Bass -- the duo behind some of the most enduring Christmas specials ever (including Rudolph the Red-Nosed Reindeer). Reinvented as a 49-minute musical, this charming cartoon stars the voice of Walter Matthau as the bedeviled Scrooge and Tom Bosley as the Jiminy Cricket-type narrator, B. Humbug, Esq. It features animation by Japanese studio Topcraft, known for their work on other Rankin/Bass films such as The Hobbit, The Flight of Dragons, and The Last Unicorn.

Winterbolt is trying to make the North Pole his evil wonderland, and it is up to Frosty the Snowman, Rudolph the Red-Nosed Reindeer and others to stop him.
