Siqueiros: Walls of Passion, a one-hour documentary film about Mexican visual artist David Alfaro Siqueiros (1896–1974) and the resurrection of his Los Angeles mural América Tropical, located at the birthplace of Los Angeles and later championed by the Chicano movement as a symbol of its oppressed culture. One of the great Mexican artists of the 20th century and one of three great Mexican muralists (with Diego Rivera and José Clemente Orozco), Siqueiros was a controversy-stirring revolutionary and lifetime activist who lived with theatrical flair and painted on an epic scale. ¡Documania!
