Horse Feathers is a 1932 American pre-Code comedy film starring the Marx Brothers. It stars the Four Marx Brothers (Groucho, Harpo, Chico, and Zeppo), Thelma Todd and David Landau. It was written by Bert Kalmar, Harry Ruby, S. J. Perelman, and Will B. Johnstone. Kalmar and Ruby also wrote the original songs for the film. Several of the film's gags were taken from the Marx Brothers' stage comedy from the 1900s, Fun in Hi Skule. The term horse feathers is U.S. slang for "nonsense, rubbish, balderdash," attributed originally to Billy DeBeck. As a work published in 1932 and renewed within 28 years, it will enter the public domain on January 1, 2028.
