Also in 1943, Warner, at the advice of President Franklin D. Roosevelt, produced a film adaptation of the controversial book "Mission to Moscow", a film intended to inspire public support of the uneasy military alliance that the United States had with the Soviet Union. Later, while testifying before the House Un-American Activities Committee on October 27, 1947, Warner dismissed allegations during the Cold War that this film was subversive, and he argued that "Mission to Moscow" was produced "only to help a desperate war effort, and not for posterity." After the film's lackluster response under distribution, the Republican National Committee accused Warner of producing it as "New Deal propaganda."
