Book excerpt: "In the 1920s, the European avant-garde embraced the cinema, experimenting with the medium in radical ways. Painters including Hans Richter and Fernand Leger as well as filmmakers belonging to such avant-garde movements as Dada and surrealism made some of the most enduring and fascinating films in the history of cinema. In The Filming of Modern Life, Malcolm Turvey examines five films from the avant-garde canon and the complex, sometimes contradictory, attitudes toward modernity they express: Rhythm 21 (Hans Richter, 1921), Ballet mecanique (Dudley Murphy and Fernand Léger, 1924), Entr'acte (Francis Picabia and René Clair, 1924), Un chien Andalou (Salvador Dali and Luis Buñuel, 1929), and Man with a Movie Camera (Dziga Vertov, 1929). All exemplify major trends within European avant-garde cinema of the time, from abstract animation to "cinema pur."
