Duck Soup (1933) - These Are My Spies

Louis Calhern is the evil Trentino of Sylvania, aiming to stir unrest in neighboring Freedonia (where Rufus T. Firefly, played by Groucho Marx, has just been made head of state), but he’s in trouble because his spies are Groucho’s brothers, Chico and Harpo, in Duck Soup, 1933.
