Continuity mistake: During the tour in the art gallery, Kurt and Elisabeth stop to listen to the tour guide. When the camera cuts to a closer shot of Kurt, a man in a brown jacket and beige sweater vest has suddenly appeared behind Kurt that was not visible in the previous shot. (00:02:05)
Continuity mistake: At the police station, there is a close up of a cup popping down out of a coffee machine as it starts to be filled. The cup is turned so the logo isn't showing. But in the next shot as a lady cop reaches to pull it out, the cup is turned so the logo is facing out towards the camera. (00:26:25)
Continuity mistake: When Jason lunges at Batman with his knife, there is a pile of garbage by the wall where he lands. In the first shot the barrel by the garbage is wooden. But in the next shot it's suddenly a metal barrel/drum. It then changes back to a wooden barrel again. (00:04:20)
