Factual error: At the end we see a soldier replacing the canister that the Zyklon B is kept in. However, he is not wearing an SS badge as all SS soldiers did. Zyklon B was only handled by members of the SS, as no other unit had authorisation to carry the sensitive stuff. (01:28:00)
Continuity mistake: When Pavel picks up the tire from the outhouse, it is a thin tyre with vertical lines, when Bruno is swinging on the tyre a few shots later, it is a thick tyre with lines both vertical and horizontal.
Factual error: At the end, When the Jews are in the gas chamber, Zyklon B is dropped in through a vent at the top. While this is correct and represents the method used by the SS, the results are not. In the film it is depicted that the victims are dead within minutes. While this is true to a degree, the actual effects took 15-20 minutes to actually kill. Yes some of the more infirm people will have died quickly but the entire chamber would not have died that quickly.
Continuity mistake: When Bruno is caught going into the front yard, he closes the gate. Camera cuts and it is open again. (00:48:10)
Continuity mistake: The landscape surrounding the prison camp changes from overgrown bushes to open plan. (00:39:10)
Continuity mistake: Bruno cuts his knee quite badly. However, the mark disappears in the following shots.
Continuity mistake: When Bruno is playing in the courtyard, we see an officer with a dog stood in the centre of the gate. Camera cuts and he is now stood to the left of the gate. (00:19:30)
Factual error: At the very start we see the Swastika flags hanging and they appear to be made of lightweight material. However, they were always made of heavier wool. (00:01:20)
Factual error: The senior SS officer visiting the commandant (and later at the funeral) is wearing two oak leaves and a pip on his collar patches. This rank badge didn't exist. Two oak leaves (without a pip) were worn by an Oberführer and three oak leaves with a pip by a Gruppenführer.
Continuity mistake: When the children are shown the new home, the girl's face is one of joy. She's smiling a nice big smile that is hard to miss. In the next shot it is one of shock and has completely changed. (00:11:10)
Answer: She represents what many people, including the wives of many Nazis, were during the time of the Holocaust: brainwashed. Many people during the time of Nazi Germany did not know what the camps truly were. They thought they were labor camps meant to keep Jews "under control" and "beneficial to society" as many thought they couldn't be trusted unless monitored. This shown in the movie where they show the "labor camps" as being resorts with swimming pools and cafes in the Nazi propaganda commercial. When she realises the camps are actually death camps; she is horrified for the reasons many others who supported Nazi Germany were horrified in real life. #1 They realised they were lied to and now have to question what they believed. #2 Many folks were afraid of Jews and did not trust them, but they did not think they were evil and deserving of death. This seems confusing in light of what we know now. However, at the time, many Germans including the wives of Nazis were brainwashed.
