Continuity mistake: At one point, when Leon is fighting with Mahogany on the train, there is a shot of blood dripping off a knife onto Leon's face. This blood later vanishes. (01:20:02 - 01:21:19)
Continuity mistake: When Maya and Jurgis arrive at Mahogany's apartment building, in order to search for evidence, it is night time. However, once they start searching his apartment, Mahogany arrives back home and you can see daylight outside his apartment windows. (00:59:31 - 01:02:55)
Continuity mistake: Throughout the film we see Mahogany attack people with his hammer and blood will spray everywhere however Mahogany stays mostly or even totally clean. A good example of this is when Leon follows him onto the train and there is a shot of Mahogany, seen through a train door, repeatedly striking a victim with his hammer and blood is spraying all over him. He's totally clean a couple of shots later however. (00:51:12)
Continuity mistake: In the opening murder scene a large stripe of blood suddenly appears across the connecting train car doors after the man slips in the pool of blood. (00:01:18 - 00:01:42)
