Continuity mistake: When the boys are on the Nemesis Inferno, Will sits at the front while the rest sit behind him, and this leaves the right outside seat free. However, when the roller coaster is moving, the mounted camera shows that Simon, Jay and Neil have all moved one seat to the right, meaning that Simon is now on the right outside seat instead of it being free.
Continuity mistake: When Jay first shouts "Bus Wankers" from Simon's car, the people at the bus stop change between shots, as does the weather. On the first viewing of the stop as we approach it, there are five people around it and it is sunny. On the shot going past the stop there are now six people at the stop. Also the weather in the second shot is now overcast and sunless. Also in the next shot of the boys laughing to Jay's outburst, there is no sign of the bus stop they've just past but in the car's interior shots you can see the Bus Stop road markings through the rear window.
