"The Great Raid" is an old-style World War Two movie about U.S. Army Rangers rescuing prisoners of war, but its makers caution it should not be seen as "flag-waving" for America's military today. Pitching a war film at a time when tens of thousands of U.S. soldiers are at war in Iraq and Afghanistan invites comparisons to the patriotic black-and-white war movies of the 1940s that tried to boost morale at home and on the front.
