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: The timing throughout this episode is bizarre. The boys leave their town in broad daylight, but by the time they get to London, it's dark. As they leave, Will's VO says they were in the club for 25 minutes, and Simon then says it's 1am, so they would have entered the club at 12:30am. Earlier, Simon said they had spent an hour looking for a parking space, so they started searching at 11:30pm. So how could they take so long to drive into London that it was broad light when they left but 11:30pm by the time they arrived? Even if they were lost in London for several hours, it would have gotten dark while they were lost, not been dark when they already arrived. This is even stranger if you consider that in the books and backstory, the boys' school is in a London suburb.
Continuity mistake: When Neil is jumping around in his Mr Monkey costume because a wasp has entered it, you can see a family of a mum, girl and a boy in a stripey T-shirt in the background and a group of onlookers. When Neil is bouncing up and down on his back, the family and the onlookers are present. When he first takes the costume's head off after standing up, there is no crowd or family of three behind him (though a second boy in similar clothing can be seen, its not the same kid who was with his family). After a cut to his friends and back, the crowd and family of three have suddenly reappeared behind Neil.

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.

Continuity mistake: After Will's taken his shoes off, they are taken by the group of younger boys behind him who start throwing the shoes between them as Will tries to get them back. The boy in blue with the number 23 on his jumper and the dark blue strip down the arms changes position between shots, from left of shot to back of shot, to left of shot.
