When Anna is running away from the Nazis she clearly has a colored nail polish on then she finds a cart to hide in and she no longer has nail polish on.
In the 1930s Lieutenant Karl Bruner would have never called Großdeutsches Reich Nazi-Germany.
Karl Bruner is wearing the four pips and strip on his uniform collar of an SS Obersturmbanfuhrer, or Lieutenant Colonel, when Colonel Henkel said he would be promoted to Captain (or Hauptsturmfuhrer) and should be wearing a collar tab with three pips (diagonally) and two stripes. Colonel Henkel's insignia is also incorrect. He is wearing the three oak leaves of a Brigadefuhrer (Brigadier General) when he should have only one leaf of a Standartanfuhrer (Colonel).
