The penultimate Napoleon scene was filmed as a cartoon in 1970 by Rankin-Bass in their 30-minute television production "The Mad, Mad, Mad Comedians". Groucho, 80 years old, reprised the role of Napoleon. Harpo and Chico had both died by then, while Zeppo declined to return, so Chico's part was performed by Paul Frees, Zeppo was reduced to a single line also voiced by Frees, while Harpo's part, having no spoken lines, was replaced by sound effects. Reportedly, Groucho was impressed by the accuracy of Frees's performance as Chico.
