Movies are the historical record. Americans experience the Vietnam War by watching "Apocalypse Now," slavery in "12 Years a Slave," and D-Day through "Saving Private Ryan." A lot more Americans watch historical movies than read history books. Which, when done well, is not a bad thing.

I've read countless books about the collapse of Nazi Germany, but the brilliantly acted and directed reenactment of Hitler's last days in his Berlin bunker depicted in the masterful 2004 German film "Downfall" can't be beat.

When a film purports to depict a historical event, it becomes the only version of what most people believe really happened.
