Visible crew/equipment: In the scene where Spoon is used as a distraction he jumps out of the bedroom window, when it goes to the werewolf's point of view you can see the set of ladders he had to climb up to get to the "window", (as the house is just 2 walls and scaffolding). This is pointed out in the DVD by one of the producers. (01:07:25)
Visible crew/equipment: As the camera follows Cooper's grenade on the floor, we can briefly see the shadow of some equipment move along the floor. (01:26:45)
