The Marx Brothers—Chico, Harpo, Groucho, and Zeppo—was a 
brother act of musicians turned movie stars. Their film comedies relied 
heavily on sight gags. Their individual stage personalities— Groucho’s 
wit, Chico’s Italian accent, and Harpo’s pantomime—have kept 
audiences laughing since the 1930s. Their films include Animal Crackers  
(1930), Duck Soup  (1933), and A Night at the Opera  (1935).
