Ballet Mécanique (1923–24) is a Dadaist, post-Cubist art film conceived, written, and co-directed by the artist Fernand Léger and the filmmaker Dudley Murphy (with cinematographic input from Man Ray). It has a musical score by the American composer George Antheil. The film premiered in a silent version on 24 September 1924 at the Internationale Ausstellung neuer Theatertechnik (International Exposition for New Theater Technique) in Vienna presented by Frederick Kiesler. It is considered to be a major work of early experimental filmmaking.

George Johann Carl Antheil ( AN-tyle; July 8, 1900 – February 12, 1959) was an American avant-garde composer, pianist, author, and inventor whose modernist musical compositions explored the sounds – musical, industrial, and mechanical – of the early 20th century. Spending much of the 1920s in Europe, Antheil returned to the United States in the 1930s, and thereafter composed music for films, and eventually, television. As a result of this work, his style became more tonal. A man of diverse interests and talents, Antheil was constantly reinventing himself. He wrote magazine articles, an autobiography, a mystery novel, and newspaper and music columns. In 1941, Antheil and the actress Hedy Lamarr developed a radio guidance system for Allied torpedoes that used a code (stored on a punched paper tape) to synchronize frequency changes, referred to as frequency hopping, between the transmitter and receiver. It is one of the spread spectrum techniques that became widely used in modern telecommunications. This work led to their induction into the National Inventors Hall of Fame in 2014.
