Which surrealist artist and filmmaker directed 'Un Chien Andalou'?

Luis Buñuel directed the Surrealist film Un Chien Andalou.

Released in 1929, Un Chien Andalou was Buñuel’s first film and was co-written with Salvador Dalí. Its short, silent narrative rejects conventional plot structure, using abrupt transitions, dream logic, and shocking images instead. The famous opening sequence, in which a razor appears to slice an eye, immediately establishes its assault on rational storytelling.

The screenplay grew from dreams described by Buñuel and Dalí, and the pair reportedly wrote it in only a few days using a rule that excluded ideas with conventional psychological explanations. Buñuel directed, produced, and edited the film, while Dalí served as co-writer and appeared briefly. A common mistake is to credit Dalí as the director; his creative partnership was central, but the directing credit belongs to Buñuel. The film became a landmark of Surrealist cinema.
