Superb movie. I've seen two other movies about the last days in the bunker. One with Anthony Hopkins and another with Alec Guinness which were both very good but this movie puts them in the dust.
Given "Downfall" is all in German and so well-acted it seems like it was shot "live" in those actual days. Its subtitled of course but you adjust quickly and it doesn't distract from the move in any way. Many of the actors bare striking resemblances to the real characters. I have read many reviews that complain this movie humanizes Hitler more but I don't really agree. I think it shows him for what he was and in no way makes him a sympathetic character. If you like well done movies and World War II interests you then I recommend this movie above all others about the last days in the bunker.
