Character mistake: When Colin points out Tarquin out to Arnie and Wayne he tells them his name is Tarquin Fitzpatrick, but when Tarquin introduces himself to Mr. Robson he says his name is Tarquin Montgomery.
Continuity mistake: Tarquin and Forbes arrive at school in Tarquin's sports car. The car keeps disappearing and reappearing during later shots of the car park.
