Giraffes on Horseback Salad
The screenplay was never produced, allegedly because Metro-Goldwyn-Mayer, the Marx Brothers' studio at the time, considered it to be too surreal (proposed scenes included gas mask-wearing giraffes, and Harpo Marx catching dwarves in a butterfly net). Other sources allege that Groucho Marx felt that the screenplay just wasn't funny.
For several years, Giraffes was thought to be lost. However, in 1996, it was found amid Dalí's personal papers.
