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.

A genius grad student organizes an all-night treasure hunt in which five rival teams composed of colorful oddballs furiously match wits with one another while trying to locate and decipher various cryptic clues planted ingeniously around Los Angeles.
