Factual error: At approximately 27 minutes in, when they part company at the airport Douglas is wearing a Combat Infantryman Badge. The CIB was not created until Oct of '43, though the scene was taking place at the end of '41 - early '42. (00:27:05)
Other mistake: When Margrete is searching her apartment for Linda with her pistol, she goes from holding it with one finger on the trigger to having two fingers on the trigger. (01:50:40)
Continuity mistake: Near the end of the movie, when Ed Leland is about to enter the Customs Office, the insignia on his hat is intact, but when he enters it has disappeared.
Continuity mistake: When Linda Voss and the children return home from the city (after the bombing) and are greeted outside by Franze-Otto Dietrich, Linda has her watch on her right wrist (as she is a lefty). As Dietrich and the children are heading into the house, you see a close up of Linda checking the time on her watch and it is on someone's left wrist. When she subsequently goes into the basement to look around, the watch is back on her right wrist again.
Continuity mistake: In the scene in Margrete's apartment, when Linda and Margrete are struggling for the gun, Linda's hands go from being bloody, then they are perfectly clean, then they go back to being bloody again.
Factual error: In the scene where Nina is in the "secret room" in the basement of Franz Dietrich's mansion and is taking photos of secret documents with her spy camera, one of the documents she photographs details the location of the secret bomb-making factory at "Peenemuende". The location of Peenemuende on the map is marked as being in the midwest Ruhr region of Germany, whereas Peenemünde in reality is located at the north-eastern part of Germany on the North Sea.
Factual error: When Von Karajan appears conducting the orchestra at the concert he looks around 55 years old. Around 1943-1944 Von Karajan was 35-36 years old and should look younger.
