1937 Marx Brothers film by Sam Wood
A Day at the Races is a 1937 American comedy film, and the seventh film starring the Marx Brothers (Groucho, Harpo and Chico), with Allan Jones, Maureen O'Sullivan and Margaret Dumont. Like their 1935 Metro-Goldwyn-Mayer feature A Night at the Opera, this film was a major hit.
