Corrected entry: When we watch the black and white footage of things that took place at The Centre in the past the camera angles change, cameras move and change focus as well. This implies that someone is there operating the cameras. It's highly unlikely that someone else would be allowed to be there when people are having psychiatric examinations, being murdered, making secret plans and so on. Unless the cameras had motion sensors which is unlikely for the time they were supposed to be happening.Charles Fraser
Visible crew/equipment: In the scene where Jarod is being thrown into the swimming pool by Zed, the gang leader, as a sort of initiation, there is a shot where Jarod is tied up in chains sitting in a chair at the bottom of the pool. Another character is set to throw in the key just to the next of Jarod and he is supposed to fall over and get it. In the shot just before he falls over, you can see a crewmen's arm holding a chain attached to the chair in order to help Jarod fall over.
