Development The screenplay of the film is based on two dreams of co-creators Buñuel and Dalí. The idea 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." The two decided to write a script based on the concept of
repressed emotions. In deliberate contrast to the approach taken by Jean Epstein and his peers, which was to never leave anything in their work to chance, with every aesthetic decision having a rational explanation and fitting clearly into the whole, Buñuel made clear throughout his writings that, between Dalí and himself, the only rule for the writing of the script was: "No idea or image that might lend itself to a rational explanation of any kind would be accepted." He also stated: "Nothing, in the film, symbolizes anything. The only method of investigation of the symbols would be, perhaps,
psychoanalysis." In his 1939 autobiography, Buñuel stated: "In the film the aesthetics of Surrealism are combined to some of
Freud's discoveries. The film was totally in keeping with the basic principle of the school, which defined Surrealism as 'Psychic Automatism', unconscious, capable of returning to the mind its true functions, beyond any form of control by reason, morality or aesthetics."
Filming The film, which was financed by Buñuel's mother, was shot in
Le Havre and at the
Billancourt Studios in Paris over a 10-day period in March 1928. It is a
black-and-white silent production shot on
35 mm film, with a running time of 17 minutes (though some sources state 24 minutes) and a physical length of 430 meters. For many years, reports on the film's notorious eyeball-slicing scene were conflicted over the eye of which dead animal Buñuel had used; sources variously claimed goat, sheep, or donkey. Buñuel later confirmed it was from a calf. Through the use of intense lighting and bleaching of the calf's skin, he attempted to make the dead animal's furry face look more like human skin. The woman who is seated on a chair and reading during the bicycle scene throws her book aside when she notices the fallen man, revealing that the book contains a reproduction of a painting by
Johannes Vermeer, whom Dalí greatly admired and often referenced in his work. In Buñuel's original script, the final shot was to feature the corpses of the man and woman "consumed by swarms of flies". Due to budget limitations, the film instead ended with a still shot of the man and woman half-buried in the sand. The film contains several thematic references to
Federico García Lorca and other writers of that time. The rotting donkeys are a reference to the popular children's novel
Platero y yo by
Juan Ramón Jiménez, which Buñuel and Dalí both hated. French filmmaker and anthropologist
Jean Rouch reported that Buñuel and Dalí ran out of money after filming was completed, forcing Buñuel to edit the film personally in his kitchen without the aid of any technical equipment. ==Reception==
