"Downfall": About the last 10 days of the war in Hitler's bunker in Berlin and probably the best war movie I've ever seen. Casting, attention to detail (uniforms, weapons, locations) are incredible and I don't think it would be possible to make it more historically accurate. Filmed in Germany and Austria and is in German and subtitled. Nominated for best foreign language film in 2004. I highly recommend if you are interested in WWII or just good war movies.
