Duck Soup (1933) - (Movie Clip) Mirror Pantomime

None of the Marx Brothers (Groucho as Rufus T. Firefly, head of the nation of Freedonia and Harpo and Chico as spies sent to steal his war plans) knows that all of them are disguised as Groucho, thus the famous “mirror pantomime” sequence with the latter two, in Duck Soup, 1933.
