Monkey Business (1931 film) in Queens, New York City. Upon alighting from the ship, the Marx Brothers' real life father (Sam "Frenchie" Marx) is briefly seen in a cameo appearance, sitting on top of luggage behind the Brothers on the pier as they wave to the First Mate. Sam Marx was 72 at the time, and the appearance was his film debut. He was paid $12.50 each day for two days work. "Monkey Business" was Norman MacLeod's solo directorial debut. One of the sequences in this film involves the four brothers attempting to get off the ship using a passport stolen from famous singer
Marx Brothers and the Marx Brothers. Most of the comedians provided their own voices for their animated counterparts, except for Fields and Chico Marx (both 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 reworking 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
