Continuity mistake: Just before Adolf's exercise with the rest of the staff, the position of Adolf's arms change between shots.
Continuity mistake: In the scene where Maria talks about wanting to throw the vase to the floor, the vase changes between shots. When she eventually throws it to the floor it's the original vase. This was most likely done due to a retake that had to be shot after the original vase was thrown to the floor and destroyed.
