Nanking (2007)

Synopsis
Filmmaker Bill Guttentag takes a closer look at the atrocities committed by the Japanese after Nanking fell to the Imperial Japanese Army in 1937 with this documentary that was inspired by Iris Chang's novel The Rape of Nanking. Compiled from over 700 hours of footage including news-reel footage, interviews with survivors and soldiers, and staged readings, Nanking was financed in large by millionaire Ted Leonsis, who had read Chang's obituary and subsequently been prompted to read the author's best-selling account of the massacre. ~ Jason Buchanan, All Movie Guide
