Duck Soup is a 1933 Marx Brothers anarchic comedy film written by Bert Kalmar and Harry Ruby and directed by Leo McCarey. It starred what were then billed as the "Four Marx Brothers" (Groucho, Harpo, Chico, and Zeppo) and also featured Margaret Dumont and Edgar Kennedy. It was the last Marx Brothers film to feature Zeppo, and the last of five Marx Brothers movies released by Paramount (Photo by: Universal History Archive/UIG via Getty images).
