Visible crew/equipment: When Paul and Barry are watching the concert, just before Paul yells "Rubbish", you can see a hand turning off the music system in front of him.
Visible crew/equipment: After the robot hears the Chuckle Brothers have found another way out (when they put up the fake wall to hide themselves from the robot) look carefully at the robot's head as it walks close to the camera, you can quickly see the cameraman in a blue shirt before it disappears behind the wall.
