The screenplay of the film “Andalusian Dog” is based on two dreams of its creators Luis Buñuel and Salvador Dali. The idea for the film began when Buñuel was working as an assistant director for Jean Epstein in France. Buñuel told Dalí at a restaurant one day about a dream in which a cloud sliced the moon in half "like a razor blade slicing through an eye". Dalí responded that he had dreamed about a hand crawling with ants. Excitedly, Buñuel declared: "There's the film, let's go and make it." They were fascinated by what the psyche could create, and decided to write a script based on the concept of suppressed human emotions. The title of the film is a hidden reminiscence from the Spanish saying: "the Andalusian dog howls-someone has died!” The screenplay was written in a few days.
