Un Chien Andalou is a 1929 silent surrealist short film by the Spanish director Luis Buñuel and artist Salvador Dalí. It was Buñuel's first film and was initially released in 1929 to a limited showing in Paris, but became popular and ran for eight months. The film has no plot in the conventional sense of the word. The chronology of the film is disjointed, jumping from the initial "once upon a time" to "eight years later" without the events or characters changing very much. It uses dream logic in narrative flow that can be described in terms of then-popular Freudian free association, presenting a series of tenuously related scenes.
