Animal Crackers, like The Cocoanuts before is an all-but-literal translation to film of a smash-hit Marx Brothers Broadway musical. The aristocratic Mrs. Rittenhouse (Margaret Dumont) holds a weekend party at her Long Island Estate. Her guest of honor is famed (but likely fraudulent) African explorer Geoffrey T. Spaulding (Groucho Marx). Also showing up are renegade musician Signor Emmanuel Ravelli (Chico Marx), the mute, girl-chasing "Professor" (Harpo Marx) and Spaulding's faithful secretary Horatio Jamison (Zeppo Marx). The film, revolving around a stolen painting, finds Groucho lecturing on his most recent safari ("One morning I shot an elephant in my pajamas. How he got in my pajamas, I don't know"), Harpo and Chico unabashedly cheating at bridge, Groucho dictating a wildly nonsequitur letter to the firm of Hungerdunger, Hungerdunger, Hungerdunger and McCormick, and Groucho and Chico drawing up plans to build a house. — Hal Erickson
