Continuity mistake: As Batman is walking through Arkham, he passes the Riddler's cell. Riddler leans up against the glass of his door with his hands against the glass near his face and mouth. When the angle changes to behind Riddler, suddenly his hands and arms are down more to chest level with his right hand outstretched towards the side of the door. (00:07:02)
Continuity mistake: After talking with Bullock on the roof, Batman is in his vehicle and talking to Hugo. On the screen, Hugo lifts up a glass to his mouth to take a drink, but when the camera cuts to a close up of the screen, suddenly his arm is lower, and he is once again lifting the glass to his face.
