Visible crew/equipment: When they are taking the major off in the car after being bottled, the camera crew can be easily seen at the bottom off the screen as they drive off. (01:16:45)
Factual error: When Wood's character and the gang go to the match which is supposed to be between West Ham United and Birmingham City the teams we actually see in the football action shots are West Ham United and Gillingham.
Factual error: Before the trip to Manchester, we see Charlie Hunham and Elijah Wood outside King's Cross station (London's station for trains to the North East & Scotland) with a GNER train in the background. In the next scene, they are shown inside Paddington station (London's station for trains to South Wales, Devon & Cornwall) catching a First Great Western train. The next scene shows a shot of a Silverlink County train, which run from London Euston to Northampton and Birmingham. In these three consecutive scenes we are shown 3 different trains, run by 3 different operators, none of which actually serve Manchester.
Revealing mistake: In the final fight scene we see Matt hitting a guy in the arm with a piece of wood. If you watch closely when he hits him the wood vibrates, indicating it is made of rubber.
Continuity mistake: When in the Abbey, Bovver is on a table singing West Ham's team song. When everyone sings "Lets go F*ing mental" and starts throwing beer on Bovver his hair gets visibly wet. It cuts to another shot then back to Bovver whose hair is now dry. He is again doused in beer, then confronts Matt in the bathroom again with dry hair and clothing.
Continuity mistake: Pete has less blood on his face when he dies and the overhead shot is on him, than what he did when Bovver was trying to help him.
Continuity mistake: When the GSE are walking to the final fight scene, Terry the barman starts off being on the right of Pete. Yet when they start charging the Millwall gang, he is now on the left.
Continuity mistake: When Matt has the Chelsea grin, he is obviously bleeding a lot in the corners of the mouth. But in the next scene with the van and then with the fight, the blood is gone and it doesn't show and sign of wounds and him wiping the blood away.
Suggested correction: The blood might have been from an injury on the inside of his mouth. And just because we don't see him wiping it away it doesn't mean it doesn't happen.
Other mistake: In the fight after Matt gets ambushed, as the gangs collide, Matt gets knocked down, yet in the next shot he gets knocked down again. How would he be able to get back up fast enough to get knocked down again straight away?
Continuity mistake: When Matt is smoking on the balcony near the end of the movie, he takes a drag on his cigarette when Shannon is talking to him. Yet in all shots afterward he never blows the smoke out.
Audio problem: When Bovver is helping Pete up on the beach, Pete says, "My mate Bovver, never could turn down a good scrap," but his mouth never moves.
Continuity mistake: When Elijah Wood wakes up the next morning after being in his first fight he has a bad bruise on his left eye/cheek. In the next scene at the breakfast cart the bruise is gone, only a few scratches are visible.
Character mistake: At the beginning of the film, Matt arrives at Paddington station in West London. He needs to meet his sister who lives in Chelsea - also in West London. However, for some bizarre reason he gets to her via meeting at Bank station - in east London. It makes no sense why he would make such a convoluted journey. Even if as a tourist he simply doesn't know London well enough to make a more efficient journey, his sister - who lives there - would correct him when arranging a meeting point.
Suggested correction: It's possible his sister knew she was going to be in that area anyway so it would be a convenient place for them to meet. There's no mistake here, just something plausible that isn't, and doesn't need to be, explained.
