Visible crew/equipment: Whilst the group of Southeast Asian men are walking through the hair salon, there is a shot that starts with a male hairdresser wafting a blanket, that pans over to the group of men and then the camera rotates around the man holding a little girl. Immediately after the camera passes the man and girl, the camera very briefly holds on another man waving to an employee. Just as this happens, the reflection of the cameraman can be seen in the mirror to the left of the shot. (00:31:30)
Plot hole: After leaving the hospital, Racine ducks into a pachinko parlor. In there, he gets a young girl to help him find a telephone and a taxi.

In the left-side view, Jake's head is straight down, resting on his right wrist. Jake's head is tilted to the left again, with his right-hand fingers almost at the edge of the table. (00:54:30)
