In 1942, Metro-Goldwyn-Meyer and the United States Office of War Information collaborated on Bataan with the official goal to increase public understanding of World War II. The first war film to take place entirely on the battlefield -- with no scenes of the soldiers on leave, depictions of the home front, or flashbacks to pre-war civilian life -- Bataan prepared its wartime audience for American casualties. Its Alamo-esque storyline emphasized the value of such sacrifice and its diverse group of soldiers --compiled of all ranks, races, classes, ages, and creeds -- portrayed this effort as the duty of all men. It is a depiction of altruism and national unity that both inspired public support of the War and served as the template for World War II films throughout the forties and into the present.
