Factual error: Approximately three quarters of the way in to the film, there is a close up of a German soldier handing an officer a file of documents. The helmet that the soldier is wearing is a post war 1960s version. This can be determined by the lack of an air vent and rivet on the side of the helmet.
Henning von Tresckow: We have to show the world that not all of us are like him. Otherwise, this will always be Hitler's Germany.
