During a holiday, in the winter of 1927, the Catalan painter Salvador Dalì decided together with Luis Buñuel to make a short film. The two artists wrote the script in just six days, applying the paranoid-critical method that Dalì was working on in those years. “An Andalusian Dog” was born thanks to a financial loan from Luis Buñuel’s mother and involves a small cast, including the two artists, without professional actors. It was first screened in September 1929 at Studio Ursulines in front of an excellent audience including Jean Cocteau, Pablo Picasso and André Breton. The short film turns out to be a truly unexpected success, contrary to what the two artists had foreseen.
