In March 1933, Herman J. Mankiewicz, a respected Hollywood screenwriter and producer, took a leave of absence from Metro Goldwyn Mayer to write a screenplay about Adolf Hitler. The former New York newspaperman, playwright, theater critic, and Algonquin Table habitué was known for his sophistication and irreverent wit. But Mankiewicz was also deeply political, and as he watched the Nazis tighten their stranglehold on Germany, he understood the implications and felt he had to act. Abandoning his usual ironic detachment, he wrote The Mad Dog of Europe in a desperate attempt to awaken the American public to the danger of Hitler’s rise to power. The story of his screenplay’s ultimately fruitless journey offers a portrait of American culture in the years leading up to World War II and the obstacles facing those who shared his prescience.
