Revealing: When Stan is in the safari park driving the bus with the monkey on the steering wheel the scene outside the bus is obviously background projection and at times it runs backwards giving the impression that the bus is in reverse when all the time it is going forwards.

Continuity: In the scene when the fire starts in the bus depot, the manager tells Stan to reverse the bus away from it, and ends up crushing Blakey's minivan. The van changes from a Morris model to a crushed Austin model, just before it is crushed.
