Hans Fallada’s book is based on a true story, and this film was made based on Fallada’s book. We saw the film in German. When I say German, I would like to point out, most actors spoke with a very strong Berlin dialect! The acting was very good. However some of the characters in this story are so disgusting that it is hard to watch them. And these very disgusting characters were the ones in powerful positions and the more gentle and better educated characters were always powerless to do anything against the most horrible excesses of those in power. The film shows what happens to simple, not very well educated people that just lead an ordinary life when for some reason they object to how the regime treats them – in this case the Nazi regime.

This movie is set into 1940 in Berlin. Maybe at the time the majority of the population would not have objected much to the way the war was handled by the Nazis. They may have still believed that it was important to support all the war efforts. The propaganda was, that you had to make sacrifices for the good of the nation. If your son died in battle, even if it was your only son, you should be proud of him that he died a war hero. And so on. Only slowly, after several years of war, more and more people would regard this continuing war as madness and wanting to protest against it. It was common knowledge that any protesters would be severely punished. The resistance fighters would have been well aware that protesting against the regime could mean certain death if they were caught.
