Brain Donors (1992) is an American comedy movie released by Paramount Pictures, loosely based on the Marx Brothers comedies A Night at the Opera and A Day at the Races (the two films the Marx Brothers did after leaving Paramount). The film co-stars John Turturro, Mel Smith, and Bob Nelson in the approximations of the Groucho, Chico, and Harpo roles, with Nancy Marchand in the Margaret Dumont dowager role.
The project was filmed as Lame Ducks; however, when the film's producers (David and Jerry Zucker) left for another studio, Paramount scrapped the publicity campaign, changed the title, and withdrew the film after its initial screenings. Brain Donors attracted attention on the home video market, which has resulted in a cult following according to its screenwriter, Pat Proft.
