When the father's coffin is taken away in a truck; there are five people consisting of family and friends running after the truck. The position as they run is first Karl-Heinz, then a male companion, then Eva is close behind the male companion, and staggering well behind are two women. However when it cuts to a mid-shot; Eva now ends up much further back in the fourth position.
When Edmund is on top of the building and looks down; there is an aerial shot of the street with bombed buildings and a sidewalk in front cleared of debris. In the following cut right before Edmund jumps an aerial shot of the street is shown again however now it is a different street containing trolley car rails and the sidewalk covered in rubble.
When Edmund jumps and it cuts to him landing; they obviously sped up the film to try to simulate a body falling from the top of the building. Apparently, they just had the actor fall from a standing position.
