Goofs

When Gary crosses off the 10th pub on the map, the figure of the "modern art" statue can be seen on the map just below the second and third pubs. But since this is the same map he used for the original crawl before The Network arrived, and since the statue is apparently part of The Network, it should not appear on the map. It is also apparent that the statue was not there at the time of the original Golden Mile since they wonder about what it is when they pass it earlier in the night.

One of the three girls swallows the wedding ring and later it's retrieved by pulling it out of her stomach, but earlier in the fight in the toilet when the boy's head came off, there were no pipes or tubes connecting the head to the stomach.

During the first big Blank fight in the pub toilets, 'Peter' falls against a urinal and comes away with white paint on his back. (Presumably, the damaged urinal was touched in with white paint between takes). When his back is seen again, the white marks are gone.

In the early scenes with Gary recruiting his buddies, his Eye of Horus necklace frequently appears and disappears from shot to shot.

At 1h 12 mins, Gary King is accused of having dislocated his elbow, requiring a metal plate to be inserted. Metal plates are used to treat bone breaks, not dislocations.

When Gary is telling the boys what he's changed on the car since they last saw it, he says "Carburettor". The car is a Ford Granada 2.8i Ghia X. This model did not have a carburettor because it was fuel-injected.

Andrew Knightley's law firm is called Beckingham, Davies and Knigthley LLB. In England, the suffix 'LLB' means 'Bachelor of Laws' and describes a person who has an undergraduate degree in Law. Law firms should bear the suffix 'LLP' ('Limited Liability Partnership').

When Gary gives the police officer his name and address as Peter Page, the postcode he tells him is invalid - in the UK, the second half of a postcode always begins with a number.

In the fight between Gary and Andy in The World's End pub, Gary's hospital band gives his date of birth as 03-Jan-1972; this would have made Gary 18 in 1990. Assuming he was not kept back two years, his school leaving date should have been June 1988 when he was 16.

In England, many pupils stay at school for a further two years in the 6th Form to take their A-level exams which means they leave at age 18. The five clearly did this because Andy went to university to study law, which requires A-level qualifications; the legal drinking age in English pubs is 18; and the minimum age to hold a UK driving licence is 17. Gary has already passed his test and owns a car.

Gary revealing to Peter and the rest of the gang that the car he bought from Peter in 1989 is still registered to him is unrealistic for multiple reasons. Firstly, until 2015, cars in the UK were required to purchase an annual or semi-annual road fund license or tax disc to display on the windscreen. The registered keeper of the vehicle would receive annual reminders through the mail when this was due. This means that Peter would still be receiving these reminders every year despite having sold the car years before. Also, Gary mentions that Peter received penalty points on his license. When a vehicle is caught speeding, a notice of intended prosecution (NIP) is sent to the registered keeper's address showing the location, date, time, and details of the offense. With Pete being a senior partner in a car dealership, he would certainly know all of this and would likely query why he was still receiving correspondence for a car he had sold years ago.
