Surrealism emerged from the Dada art movement in the early 20th century. Surrealist films aimed to explore taboo topics like sex and religion by using unconventional editing techniques that juxtaposed random objects and events. Two influential early surrealist films were Un Chien Andalou (1929) and L'Age D'Or (1930) directed by Luis Bunuel, which featured surreal imagery and disrupted narrative continuity. While surrealism aimed to be free-form, filmmaking requires planning, raising questions about whether the medium is suited for surrealist ideals. The films of Jan Svankmajer provide an example of highly planned surrealism that was still anti-establishment.
