Factual error: On a number of occasions uniformed Wermacht officers and men are shown saluting Albert Speer. Speer was a civilian and (obviously) not in uniform. Military men do not salute civilians.
Factual error: In the scene where a chemist is preparing a solution to give to Mrs. Goebbels which she uses to kill her six children, the chemist is holding a modern day conical flask with the brand name "Schott" marked on it. Flasks pre-1950's did not have these markings.
Factual error: Traudl Junge originated from Munich, Bavaria. Her accent though is not Bavarian. That she really spoke with a Bavarian accent can be checked in later interviews.
Factual error: Hermann Fegelein is (correctly) addressed as Gruppenführer throughout, but wears the collar patches of an SS Brigadeführer.
Suggested correction: Speer, in his capacity as Reichsminister of Armaments and Munitions, would have been very recognizable to all Germans at this time and respected. Additionally, no Wehrmacht members actually salute or interact with Speer (by my memory), only Waffen-SS, who would doubtless be more loyal to a senior party member and willing to salute him. More so, if the entry refers to the Hitlergruß, the Hitlergruß was given regardless of rank per National Socialist ideology related to social equality.
One of Speer's many defences at his postwar trial was that he was a civilian, mistrusted by the military and never accorded military courtesies, which included them saluting him.
