I watched this last night and I highly recommend it. It’s a chronicle of the last few days in Hitler’s bunker, based off of the memoirs of one of his secretaries who was there. What makes it unique is that it’s probably the only movie I’ve ever seen that depicts the Nazis as actual people. It’s not a sympathetic portrayal, but a realistic one. “The Nazis” have become such a Hollywood cliche that they are shown in practically every movie as essentially being a group of comic book villains. Indiana Jones and Hellboy come to mind. Even realistic war movies like Patton and Saving Private Ryan don’t treat the Nazis as actual human beings, but as some intangible evil against which the Allies are fighting. Downfall shows the war from the vantage point of the Nazis and tries to recreate the atmosphere that existed in the last few days of the Third Reich.
As a sidenote, I had never even heard of this movie until recently, but one particular clip has become quite the YouTube phenomenon. People have taken to removing the original subtitles and replacing them with hilarious new ones so that Hitler is ranting about having his bike stolen, http://www.youtube.com/watch?v=nmEAo-nzBgY, etc. The latter is the first one that got my attention.
