Factual error: In the American Embassy scene, when 47 opens his jacket for the security guard, the base plates of the magazines loaded in his Silverballers are marked as .38 Super. The Silverballers, however, should be chambered in .45 ACP. His spare magazines are marked as .45. (00:27:05)Nitzan Shinnies
Factual error: In the fighting scene in U-Bahnhof Alexanderplatz the underground trains move much faster than in real world. Alexanderplatz is a railhead station. The trains would either crash into a wall or would not have enough room to accelerate that fast.
