Factual error: Firearm issues abound throughout the film. The British detectives (who all seem to be armed, rather than a low proportion of AFO (Authorised Firearms Officers) as in real life) are shown carrying Beretta pistols, even though the Metropolitan Police issue the Glock 17. The SFO (Specialist Firearms Operations) officers are shown carrying MP5 submachineguns, which is accurate, but fitted with cheap toy-shop lasers. Weapons handling is poor throughout, with chickenwing syndrome particularly prevalent. Weapons carriage also appears geared to look "cool" rather than realistic; shoulder holsters - which practically everyone wears in this film - are rarely used for concealed carry in reality.
Other mistake: In the sequence where Bo is taking his driving test, the driving instructor is shown fumbling to put on his seatbelt three times, all of which are from the same piece of film. (00:00:45 - 00:02:45)
Continuity mistake: During the complete car-bomb chase sequence towards the end of the film, Michael Clayton's car is shown in one shot without its lights on. All the surrounding shots in the scene have both cars with their lights on. This is also a slightly revealing error because it shows that they actually filmed these sequences during the day using neutral density filters. (01:41:15)
Continuity mistake: In the scene where Randy is playing table tennis on the stage at the restaurant, just after he has finished hitting the ball blindfolded and says, "Thank you", you can see a man in the background getting up. The shot then switches to the boy with the man in the background still sitting. The shot then switches back to Randy and the man is getting up again.
Plot hole: Spoiler! We find out that "Rogue" is actually Tom Lone, who killed the real Rogue and destroyed his face to prevent identification, then had plastic surgery and went underground to get revenge. But how is the body never identified? Lone was a cop, they'd have blood type, DNA etc. on file, which would have proved the body wasn't his.
Continuity mistake: At the beginning, in the scene where Rayne finds two bodies near a small house, she takes out one of her blades. Firstly, she grabs it in a wrong way (the tonfa-like blades should be held under the arm), but when the camera angle changes she holds it properly.
Visible crew/equipment: When George drops Lee, Carter and Genevieve off outside the embassy to meet Reynard, right before George tells them he won't be there when they get back, as the camera moves around the car a reflector screen and a crew member can be seen reflected in the side window of the car.
Continuity mistake: When the guys are being hit by bugs, you see Woody drive past everyone, when he gets hit by the bird you see him passing everyone again.
Continuity mistake: After Evans was shot near the end of the movie, Ben Wade jumped out of the train to look at him. If you look over Wade's shoulder, you will see that Nez (the Apache) had already arrived at his spot, and Campos (the Mexican sharpshooter) threw Wade's gun belt to Charlie Prince. After the movie cut a couple of times, Nez was shown walking up, throwing Wade's gun belt to Campos, who then threw it to Charlie Prince.
Continuity mistake: Mike avoids colliding head-on with a pickup by swerving off the road into a farm field. He does this after passing a tractor and flatbed truck to his right. The shot changes and he is turning off the road into the field between the tractor and truck. (01:36:50)
Revealing mistake: When Conrad throws the Russian over the cliff, as the Russian explodes, you can see that poor CGI actually makes him transparent.
Continuity mistake: When Ben and Gwen are fighting off aliens on Incarcecon, right after the tetramand destroys the hoverboard, the Omnitrix is missing from Ben's wrist.
Factual error: The Commissioner's secretary, a police constable, wears a shoulder number consisting of four digits only. Metropolitan Police constables' shoulder numbers always have two letters above three digits.
Revealing mistake: At the end, there is a group of people with their backs to the camera, facing & waving to the Fantastic 4. As the F4 fly towards the camera and out of the shot, the crowd turns to continue waving to them. One small boy in white remains facing the wrong way, still waving, until another child grabs the back of his clothes & turns him to face the right way.
Continuity mistake: At the beginning, the undercover cop says the combination is 666. But the lock has a 4 digit combination.
Visible crew/equipment: You can see a member of the crew walk by inside Monk's house when Elizabeth and Monk are sitting outside of his home talking about their future plans together.
Revealing mistake: By the end of the movie, when Jamie Foxx is holding the dying Arabian cop, you can see that Jamie's neck injury looks extremely false.
Visible crew/equipment: When El Wray and the police arrive at the hospital as Dakota drives off, at the very back of the shot is the crane used for the lighting (confirmed on audio commentary).
Continuity mistake: The writing on Ghost's sword early in the film has the Turisas rune (representing TH in Thunder) near the hilt, but later not only is a different font used but now the Dagalas rune (representing the D in sword) is at the hilt.
Factual error: Hadrian's Wall is facing the wrong direction. The Wall was built to defend Britannia from the Picts in Scotland; therefore, its front should face north. However, as the Romans approach it from the south, they are greeted by the sheer face of the Wall.
Suggested correction: Not necessarily a mistake. Little kids can have a hard time keeping track of/focusing on things. I know little kids that have a hard time looking in the direction of the camera when their picture is being taken.

There's a difference between not looking at a camera when you don't care about having your picture taken and being able to follow superheroes that pass you, especially if you're waving at them. The reason it's a revealing mistake is because everyone involved had to pretend superheroes were passing them and the kid didn't know when to turn.
