The Mad, Mad, Mad Comedians
originally aired on ABC
It was Rankin/Bass' second hand-drawn animated work to be outsourced to Osamu Tezuka's Mushi Production in Tokyo, Japan. The show aired on ABC on April 7, 1970 before the airing of that year's Oscars. Most of the comedians provided their own voices for their animated counterparts, except for Chico Marx and W. C. Fields, both deceased, Zeppo Marx and Harpo Marx.
