Sunday Night at the Movies: DUCK SOUP

The Mirror Gag, a classic entree that goes back through burlesque, vaudeville and music hall to the European circus ring and most likely all the way back to Commedia.

It's been done recently in the ring by the Chickys, to much acclaim. It's been done on TV by Lucille Ball and Harpo Marx. Here it is done by the Marx Brothers in the 1933 film DUCK SOUP directed by longtime Hal Roach writer, director and gag man, Leo McCarey.
