Visible crew/equipment: In the director's cut, there's a scene where the bar-owner is tied up to the bed. A few seconds before it cuts away, a crew member's leg can be seen on the left hand side.
Visible crew/equipment: Halfway through the big car chase, just after a black-and-white police car also joins in, you will see the cars navigating through an S-turn, heading toward the river.

Visible crew/equipment: In the scene where the Lucky Spot gang is talking about something at the bar, and they are the only ones there, you can see a boom mic coming into picture.
