Continuity mistake: Gar enters a room and leaves the door open. Throughout the whole mirror scene the door is also open both when the camera looks at him and when the camera points at the mirror. However, when he is about to leave the room he needs to open the door as it has been closed inbetween us looking at Gar in the mirror and looking at him normally. (00:17:50 - 00:18:35)
Factual error: When Starfire gets out of the totalled car, there is a road sign visible. It is a settlement exit sign, denoting the exit of Königsstetten and Zeiselmauer as next settlement ahead. Obviously the makers tried to be extra thorough nailing down their "outside Vienna" location. They started OK - both Königsstetten and Zeiselmauer actually ARE outside Vienna - but then they completely botched it: Not only did they use a German black-on-yellow "StVO Zeichen 331" instead of the Austrian "StVO Hinweiszeichen 17b" which has black writing on a white base with a blue rim and doesn't list the next settlement, but they also put 852km as the distance to the next settlement, which is more than the length of Austria west to east. The real distance is 3.8km.
