Hollywood's Unofficial Film Corps shows that Rosten, Schulberg, and others--including Garson Kanin, George Cukor, Stanley Kramer, and Jules Buck--created movies that were both entertaining and politically expeditious for US war aims. At the same time, in an effort to unify the American public, they avoided focusing on the fate of European Jews, even while addressing racism and antisemitism in the United States. Jewish themes were often downplayed, and Jewish directors, writers, and other contributors frequently went uncredited. As Berkowitz writes, "Rosten's cohort changed feature films forever." Thanks to his research, we now have a better understanding of how and why.
