I love foreign war films and have a decent collection of Korean, Chinese, French, German and Russian films.
I recently bought this German made war film "Downfall" (German language with subtitles). It's set in the amazingly tense final days of WWII in Europe from within Hitler's underground bunker in Berlin, as the Russians close from the East and the Allies from the West. See Hitler's mental decline and how his personal staff strive to handle the hopeless situation to the point of desperation as the Third Reich comes to an end.
An amazing film that deserves to be seen by everyone. Buy it and pass it on to your freinds. I can't recommend it highly enough.
Also see these amazing war films : "Brotherhood", "Saints & Soldiers", "Days of Glory", "Stalingrad", "Joint Security Area" and "The Star".
