Continuity mistake: In the scene where Edward and Carter are on the plane, Edwards book keeps changing position from mostly open to mostly closed, as well as the amount read varies. (00:45:20)
Factual error: During "School Challenge" the volume of a sphere is given as Pi R cubed. It should be four thirds Pi R cubed.
Audio problem: At the scene where Mikey asks the elder penguin if anyone surfs in Shiverpool, when he says,"You know you're standing on thin ice," his beak never moves.
Continuity mistake: In the scene where Dakota is having sex with Aubrey's boyfriend, it specifically shows that her bra is off. Once they finish, and she is getting off of him, she is covering her chest with the sheet. When she does this, her side isn't covered and you can that she is now wearing a black bra.
Revealing mistake: When Dewey is singing the protest song about midgets in 1966, modern cars can be seen driving in the background.
Continuity mistake: In the railway station where 47 is being followed by the FSB, Interpol and the older agent, you see the older agent running down the ramp to platform 9 after 47. His jacket is flying up in the back, and there is no weapon visible. When he stops running, he reaches behind him into the waistband and produces a handgun with a silencer.
Revealing mistake: During the heavy snowstorm, the telephone wires are still, even though it's a blizzard.
Continuity mistake: During the scene with the picture of the teacher with breasts. Link's and Amber's seats move. Link's seat is behind the desk and then its in front moving Amber's seat over towards the center of the desk.
Continuity mistake: First day in class, when Hoager "beeps" at Jesse, Mrs. Myers writes two words. The word "verb" is over the word "subject" on the board, in the close-up. After she turns around, in the following shots, the word "predicate" appears, disappears, then reappears and "subject" is written over "verb" now. Additionally, during this scene, all the other writing on the blackboard changes between shots as well. (00:06:15)
Other mistake: When Jennifer and Gary are scratching the messages to each other on the painted glass, the glass is painted black on both sides so they wouldn't be able to see each others scratchings as the paint on their side would cover the marks the other was making.
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.
Visible crew/equipment: When Jamie leaves his father's house to meet Henry at the theatre, a member of the production crew can be seen standing behind a bush in the garden as his car reverses.
Suggested correction: It's the gardener seen earlier in the film when Jamie first arrives.
Factual error: In the final scene where Congress is supposedly passing the bill, they are still in the committee room. Bills are not passed there, but in the actual meeting halls of the House and the Senate.
Continuity mistake: Near the end, when Lucy tries to get into the building, she is blocked by police officers holding clubs straight ahead in front of them. The scene cuts to a roof shot, then back again, and Lucy tries again, but the clubs are missing, the cops just have their hands out in front of them.
Continuity mistake: The "Power Play" scene when Eric and Hanssen are in the car after a cancelled meeting (13). With Eric's line, "There's construction on E Street," the Kennedy Center appears behind his head, but in the next shot of him ("Sir, I'm SSG.,") the Kennedy Center shows up again, this time farther ahead of the car. (01:05:55)
Continuity mistake: In the shot just before Jules' friend asks, "Can you get us booze?" Seth's collar is folded inwards. In the shot just afterward, it's unfolded, partially obscuring the strap on his bag.
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)
Factual error: When Bob Ford opens the box under the bed, on top is an issue of "The Jesse James Stories" weekly, which was published from 1901-1903 - fully twenty years after the events of this film. (00:36:10)
Factual error: In the scene when Kale uses the lamp, taking off its lamp-shade, to see what's inside the hole, he points it in there. The lamp, actually, shouldn't illuminate the wall in one point creating a circle like a flashlight but wholly lighten the larger area. (01:30:00)
Continuity mistake: While Jon is fixing his contracture with the weight on the door, the position of Wendy's toast on the plate keeps changing depending on the angle.
