Visible crew/equipment: Binky and Turnip chase the protagonists after they cashed in. They crash into a toy stall, with the crash shown in a quasi-POV shot. To get that shot, a camera was mounted inside the car, obviously. The problem is, for the next 3 cuts, you can see that camera. (00:27:50)
Visible crew/equipment: During the opening credits, when Sue steps down from the helicopter, the filming crew is reflected on the cockpit glass.
Visible crew/equipment: McCoy is replaced by an obvious stunt in the wide shots of him standing inside the basket of the crane. (01:09:56)
