In 1970, the four Marx Brothers had a brief reunion of sorts in the animated ABC television special "The Mad, Mad, Mad Comedians", produced by Rankin-Bass animation (of "Rudolph the Red-Nosed Reindeer" fame). The special featured animated re-workings of various famous comedians' acts, including W. C. Fields, Jack Benny, George Burns, Henny Youngman, the Smothers Brothers, Flip Wilson, Phyllis Diller, Jack E. Leonard, George Jessel and the Marx Brothers. Most of the comedians provided their own voices for their animated counterparts, except for Fields and Chico Marx (both of whom had died) and Zeppo Marx (who had left show business in 1933). Voice actor Paul Frees filled in for all three (no voice was needed for Harpo). The Marx Brothers' segment was a re-working of a scene from their Broadway play "I'll Say She Is", a parody of Napoleon that Groucho considered among the brothers' funniest routines. The sketch featured animated representations — if not the voices — of all four brothers. Romeo Muller is credited as having written special material for the show, but the script for the classic "Napoleon Scene" was probably supplied by Groucho.
