"One morning I shot an elephant in my pajamas," explains Groucho Marx. "How he got in my pajamas I dunno." What movie is this from?

The four Marx Brothers: Groucho, Harpo, Chico, and Zeppo starred in a movie "Animal Crackers" (1930). This film is a musical comedy that was directed by Victor Heerman. It was adapted from an originally successful 1928 Broadway musical of the same title by George S. Kaufman and Morrie Ryskind. With songs by Bert Kalmar and Harry Ruby, the movie version, filmed in Astoria, Queens, New York, was released on August 23, 1930. It was in this film that Groucho Marx used the joke "One morning I shot an elephant in my pajamas.". "How he got in my pajamas I dunno."

The basic plot concerns explorer Captain Jeffrey T. Spaulding (Groucho), attending a party in his honor at the estate of society matron Mrs. Rittenhouse. The key characters are investigating the theft of a valuable painting during the party. The bulk of the movie consists of a succession of comedy sketches, one liner jokes, and visual gags. Because it was a critical and commercial success in theaters and the movies, he stage show version even today has occasionally been revived by theatrical companies.
