The Marx Brothers' greatest and funniest masterpiece - the classic comedy Duck Soup (1933) is a short, but brilliant satire and lampooning of blundering dictatorial leaders, Fascism and authoritarian government. The film, produced by Herman Mankiewicz, was prepared during the crisis period of the Depression. Some of its clever gags and routines were taken from Groucho's and Chico's early 1930s radio show Flywheel, Shyster & Flywheel. Working titles for the film included Oo La La, Firecrackers, Grasshoppers, and Cracked Ice.
It was the Marx Brothers' fifth film in a five-picture contract with Paramount Studios, before they went on to MGM. It was their last and best film with the studio. The film was directed by first-class veteran director Leo McCarey (who would go on to direct The Awful Truth (1937), Love Affair (1939), Going My Way (1944), and An Affair to Remember (1957) - a remake of his 1939 film), and its screenplay was written by Bert Kalmar and Harry Ruby (with additional dialogue by Arthur Sheekman and Nat Perrin). Originally, it was to have been directed by Ernst Lubitsch. The film was devoid of any Academy Award nominations.
