The turbulent years of the 1930s were of profound importance in the life of Spanish film director Luis Buñuel (1900-1983). He joined the Surrealist movement in 1929 but by 1932 had renounced it and embraced Communism. During the Spanish Civil War (1936-39), he played an integral role in disseminating film propaganda in Paris for the Spanish Republican cause. Luis Buñuel: The Red Years, 1929-1939 investigates Buñuel’s commitment to making the politicized documentary Land without Bread (1933) and his key role as an executive producer at Filmófono in Madrid, where he was responsible in 1935-36 for making four commercial features that prefigure his work in Mexico after 1946. As for the republics of France and Spain between which Buñuel shuttled during the 1930s, these became equally embattled as left and right totalitarianisms fought to wrest political power away from a debilitated capitalism. Where it exists, the literature on this crucial decade of the film director’s life is scant and relies on Buñuel’s own self-interested accounts of that complex period. Román Gubern and Paul Hammond have undertaken extensive archival research in Europe and the United States and evaluated Buñuel’s accounts and those of historians and film writers to achieve a portrait of Buñuel’s “Red Years” that abounds in new information.
