"One morning, I shot an elephant in my pajamas. How he got in my pajamas I'll never know."
Captain Jefferey T. Spalding

Animal Crackers is the second Marx Brothers comedy film and directed by Victor Heerman in 1930. The play that the movie is based upon, in which the Marx Brothers played on Broadway, was written by George S. Kaufman, Morrie Ryskind, Bert Kalmar, and Harry Ruby. The adaption to the movie screen was done by Morrie Ryskind. The film is in black and white and runs for 97 minutes.

This is one of my favorite Marx Brothers films. Animal Crackers starts with the famous African explorer, Captain Jefferey T. Spalding, returning to America. A rather wealthy woman, Mrs. Rittenhouse, is commerating a party to Spalding with a public viewing of a rather rare painting. However, a couple of thefts are planned by different groups and madcap comedy follows in the attempts to find the thieves.

The movie was actually unseen from 1930 to 1974 due to copyright problems with MCA/Univeral, the owner of the film, and Paramount Pictures, who produced it. Groucho Marx, with groups of film students, campaigned to have it released to the public audience. It finally was released on prime television.
