A man holds a woman's eye wide open, takes a blade to her pupil and slashes it. We all remember these images. In 1929, Luis Buñuel and Salvador Dali joined their extraordinary imaginations to make this short film. It became surrealism’s most important film-manifesto. Exploring the tumultuous relationship between a man and a woman, the dislocated narrative combines subversive images, erotic and strange, rejecting rational explanation. Un chien Andalou remains a symbol of creative freedom.
