announced that Tzara had started work on a screenplay. In 1930, he directed and produced a cinematic version of Le Cœur à barbe, starring Breton and other leading Surrealists. Five years later, he signed his name to The Testimony against Gertrude Stein, published by Eugene Jolas's magazine transition in reply to Stein's memoir The Autobiography of Alice B. Toklas, in which he accused his former friend of being a megalomaniac. The poet became involved in further developing Surrealist techniques, and, together with Breton and Valentine Hugo, drew one of the better-known examples of "exquisite corpses". Tzara also prefaced a 1934 collection of Surrealist poems by his friend René Char, and the following year he and Greta Knutson visited Char in L'Isle-sur-la-Sorgue. Tzara's wife was also affiliated with the Surrealist group at around the same time. This association ended when she parted with Tzara late in the 1930s. At home, Tzara's works were collected and edited by the Surrealist promoter Sașa Pană, who corresponded with him over several years. The first such edition saw print in 1934, and featured the 1913–1915 poems Tzara had left in Vinea's care. In 1928–1929, Tzara exchanged letters with his friend Jacques G. Costin, a Contimporanul affiliate who did not share all of Vinea's views on literature, who offered to organize his visit to Romania and asked him to translate his work into French. Affiliation with communism and Spanish Civil War Alarmed by the establishment of Adolf Hitler's Nazi regime, which also signified the end of Berlin's avant-garde, he merged his activities as an art promoter with the cause of anti-fascism, and was close to the French Communist Party (PCF). In 1936, Richter recalled, he published a series of photographs secretly taken by Kurt Schwitters in Hanover, works which documented the destruction of Nazi propaganda by the locals, ration stamp with reduced quantities of food, and other hidden aspects of Hitler's rule. After the outbreak of the Spanish Civil War, he briefly left France and joined the Republican forces. Alongside Soviet reporter Ilya Ehrenburg, Tzara visited Madrid, which was besieged by the Nationalists (see Siege of Madrid). Upon his return, he published the collection of poems Midis gagnés ("Conquered Southern Regions"). Some of them had previously been printed in the brochure Les poètes du monde défendent le peuple espagnol ("The Poets of the World Defend the Spanish People", 1937), which was edited by two prominent authors
