Other mistake: When Stan is towing Arthur's motorbike and sidecar behind the bus the tow rope was attached to the handle bars, when the handle bars come off, the bike naturally breaks away from the bus and rolls off on its own, but it is going back the way it was when it was being towed. The bike couldn't have turned 180 degrees with no handle bars to steer it.
Other mistake: The opening credits misspell the name of production supervisor Peter Sczygiol ('Sceygiol') and firearms technician Gino Vagniluca ('Vigniluca').
