Continuity mistake: During the opening scene of the film we see two boxers fighting in Julian's boxing club. The fighter in red trunks knocks out the one in blue trunks and is announced the winner. Two men then come into the ring and, between shots, we see them pick up the loser off the floor twice. (00:02:51)
Visible crew/equipment: After Julian finds out about his brother's murderer we see him washing his hands in a sink and the water turns to blood (indicating the start of another dream/subconscious sequence). Then Julian appears standing in a dark hallway outside an open door, something about the room scares Julian, and he walks away from the door. As the camera moves backwards down the hallway you can see its distinct blocky shadow cast on the wall. (00:27:08)
Visible crew/equipment: When Julian follows Chang around the streets, during the second point-of-view shot from Julian's perspective, you can see the distinct shadow of a cameraman with a camera on his shoulder cast on the wall. (00:38:02)
