In 1942, the film won an Oscar in the Best Picture category and both Greer Garson and Teresa Wright won an Oscar in the Best Actress and Best Supporting Actress
William Wyler and Roosevelt wanted prints rushed to theaters nationwide.

Between 1942 and 1945 Wyler volunteered to serve as a major in the United States Army Air Forces
