Animal Crackers (1930)

Filled with comedy sketches, musical numbers and plenty of gags, Animal Crackers is often regarded as the Marx Brothers' most quoted film for its witty and unforgettable dialogue. Groucho stars as Captain Spaulding, a famed African explorer who is being honored at a high society party at the estate of Mrs. Rittenhouse (Margaret Dumont). Mayhem and chaos ensue after a valuable painting disappears and Spaulding, along with the Professor (Harpo), Signore Emanuel Ravelli (Chico) and Horatio (Zeppo) "help" search for it. Highlighted by musical performances including "Hooray for Captain Spaulding" (which would later become the theme song to Groucho's popular TV series You Bet Your Life)
