Animal Crackers (1930, directed by Victor Heerman), was adapted from a successful 1928 Broadway musical of the same title by George S. Kaufman and Morrie Ryskind, also starring the Marx Brothers and Margaret Dumont. The film, distributed by Paramount Pictures, was the second of two films the Marx Bros would make in New York.
The well-known explorer and hunter Captain Spaulding (Groucho) has just returned from Africa, and is being welcomed home with a lavish party at the estate of influential society matron Mrs. Rittenhouse (Margaret Dumont) when a valuable painting goes missing. The intrepid Captain Spaulding attempts to solve the crime with the help of his silly secretary Horatio Jamison (Zeppo), while sparring with the anarchic Signor Emanuel Ravelli (Chico) and his nutty sidekick The Professor (Harpo).
