After Rabe leaves Nanjin, there is a scene showing the execution of 3 Chinese men tied to posts. After the execution, when the man on the right post is untied and his body laid on the ground by guards, one can clearly see the actor lowering his head down slowly on the ground. The head of a dead body would have dropped more massively.
Several scenes take place on a square where stands what seems to be a ruined large public building. Towards the end, this building is shown from another angle, but it is clear from its shape that the image has been flipped horizontally.
