Continuity mistake: In one scene after Hutch is beaten up on the bus, he has no facial injuries. Then in the next scene, they are back.
Continuity mistake: RZA is first seen using a bolt action rifle in a left-handed configuration but in later shots the rifle is right-handed. Not sure if they mirrored the image in the close up because they couldn't get the right camera angle or if they were genuinely trying to make his character appear left-handed. (01:16:02 - 01:17:49)
