Susan Alva Fleming was an American actress and the wife of comic actor Harpo Marx and sister in law to Groucho, Chico, Zeppo and Gummo. Fleming was known as the "Girl with the Million Dollar Legs" for a role she played in the W. C. Fields film Million Dollar Legs (1932). Her big stage break, which led to her Hollywood career, was as a Ziegfeld girl, performing in Rio Rita.

Arthur "Harpo" Marx was an American comedian, actor, mime artist, and harpist, and the second-oldest of the Marx Brothers. In contrast to the mainly verbal comedy of his brothers Groucho and Chico, Harpo's comic style was visual, being an example of vaudeville, clown and pantomime traditions. He wore a curly reddish blond wig and was silent in all his movie appearances, instead blowing a horn or whistling to communicate. Marx frequently employed props such as a horn cane constructed from a lead pipe, tape, and a bulbhorn.
