Which of the following film titles is a 'Marx Brothers' film?

Duck Soup is a 1933 Pre-Code Marx Brothers comedy film written by Bert Kalmar and Harry Ruby, with additional dialogue by Arthur Sheekman and Nat Perrin, and directed by Leo McCarey. First released theatrically by Paramount Pictures on November 17, 1933, it starred what were then billed as the "Four Marx Brothers" (Groucho, Harpo, Chico, and Zeppo) and also featured Margaret Dumont, Louis Calhern, Raquel Torres and Edgar Kennedy. It was the last Marx Brothers film to feature Zeppo, and the last of five Marx Brothers movies released by Paramount Pictures.

Compared to the Marx Brothers' previous Paramount films, Duck Soup was a box office disappointment, although it was not a "flop" as is sometimes reported. The film opened to mixed reviews, although this by itself did not end the group's business with Paramount. Bitter contract disputes, including a threatened walk-out by the Marxes, crippled relationships between them and Paramount just as Duck Soup went into production. After the film fulfilled their five-picture contract with the studio, the Marxes and Paramount agreed to part ways.
