The Marx Brothers were a family comedy act, originally from New York City, that enjoyed success in vaudeville, on Broadway, and in motion pictures from 1905 to 1949. Five of the Marx Brothers thirteen feature films were selected by the American Film Institute (AFI) as among the top 100 comedy films, with two of them (Duck Soup and A Night at the Opera) in the top twelve. The brothers were also included in AFI's 100 Years...100 Stars list of the most significant screen legends, the only performers to be inducted collectively . The core of the act was the three elder brothers, Chico, Harpo, and Groucho; each developed a highly distinctive stage persona. The two younger brothers, Gummo and Zeppo, did not develop their stage characters to the same extent, and eventually left the act to pursue other careers. Gummo was not in any of the movies; Zeppo appeared in the first five films in relatively straight (non-comedic) roles.
