Three things of note:
- The actor who plays Hitler, in the film The reader plays a Jewish Law professor, who's class attends a post war war-crimes trial, where former female SS guards are tried.
- The film Der Untergang (= Downfall) is primarily based on the statements/memoirs of Traudl Junge; some of the events depicted (like some of the suicides and murder of the Goebbels children are disputed). Honestly, if you can, watch the movie in German, with English subtitles. Might also help if you read up a little on the primary figures of the movie (Wiki should be sufficient) and the setting of the movie before you watch it. I know I performed the role of 'instructor' to both a flatmate and one of my classes when they watched the movie, and they really appreciated it. If you do not know anything (or merely the bare minimum) of the background, there is a chance you will miss a lot, and some parts of the movie might not be understood.
- There is one scene - the handing out of the Iron Crosses - to the youngsters that is actually based on existing film footage (propaganda film). IIRC it was the uncut footage which proved Hitler's shaking hand, which some attributed to either mental break down or a nerve/brain disease (Alzheimer or something like that).
