Factual error: Viggo is "playing" the bagpipes on the wrong side. They should be under his left arm, not his right. He is also not blowing hard enough to make the required sound. They sound good, though.
Factual error: For the third movie in a row -at least they are consistent - Maggie introduces herself as Detective of the SFPD, but detectives are not referred as such, but as Inspectors.
Factual error: In the montage showing James busking after committing to the program, he picks up his guitar when it gets dark and tries to find shelter. On the side of a London bus, you can spot the ad for "The Hunger Games; Mockingjay - Part 2", a movie that came out in 2015. The happy ending of this movie takes place in 2012. (00:09:55)
Factual error: In the scene when they are locked in the garage, they attempt to use vehicle air bags to propel themselves through a garage vent in the roof. It is absolutely impossible for a air bag to deploy by jumping on it. A air bag requires specific battery voltage and resistance supplied by a air bag control module to deploy a air bag. The physical act of jumping on it will not deploy it.
Factual error: Toward the end of the movie, we see a B-2 Spirit releasing bombs over the town. This is very unlikely, as this is probably the most expensive aircraft to operate in the USAF arsenal, and it has only 20 of them. There is no reason to use it over an area with no hostile enemy fire, when much cheaper and more available aircraft can to the same task.
Factual error: When Pete is riding on the back of the school bus and jumping on top of the bus in the background a New Zealand style Give Way sign is seen and also on the left hand side of the road. The film is set in the USA so this should have been on the right hand side of the road. (00:34:00)
Factual error: In the wedding and arrest scene the U.S. Customs Service officials have police attack dogs. The U.S. Customs Service only has drug detection dogs. (01:57:00)
Factual error: The open credit sequence takes place at the Atlanta Airport (Hartsfield Jackson), signs are throughout the Delta terminals, Boston Airport announcements are dubbed in until we see John Cusack come off the airplane.
Factual error: Many details are wrong in Elizabeth's execution. The scaffold is in the prison yard, whereas by this time it was inside. The noose has a knot as opposed to the simple slider which was used by this time. Nobody is present except the hangman and one warder, whereas in fact the usual execution party was the prison governor, the chaplain, at least two warders, the hangman and his assistant. The hangman is masked, which never happened in Britain.
Factual error: Curiously enough, Michelle's mess in the bathroom with the self-tanning spray seems to be mostly made by footprints everywhere (but you don't tan your palms and soles, and the bottom of the foot is what she is using to lean on the wall anyway) while the spray she continues to apply does not color the tiles and towel in the slightest and nothing drips from the smooth surfaces.
Factual error: The limo shown is a 1990 (or later) Cadillac. It has large halogen headlamps and not the dual headlamps of a 70-71.
Factual error: There would be no room for a thumb drive inside of a real Rubik's Cube due to the way they are constructed. When dismantled, the individual moving parts are quite small. It would certainly be possible to construct a facsimile of a Rubik's Cube that would have enough room, but it wouldn't be a fully functional puzzle the way it was in the film.
Factual error: As it happens in many Hollywood movies, we have a gun that is "ceramic" (actually a polymer, "plastic" as Ben corrects himself later) that is entirely stealthy, able to fool the metal detectors at the entrance of a building. It's not an imaginary high-tech device, but is explicitly referenced as the FN Five-seveN handgun (here called repeatedly as FN Five point seven). The metal detector would still pick up the metallic parts and the bullets. (00:40:25)
Factual error: When the boy sends the letter, it already has a postmark.
Factual error: Kim is seen using a first generation iPhone in the 2006 scenes. The iPhone was not released until summer 2007.
Factual error: After Calvin logged in a bank account with admin password on his Acer PC at home, he speaks about Chinese bank accounts. But the displayed CH stands for Switzerland. China would be CN. (00:30:30)
Factual error: The nearest tube station to Wembley Stadium is Wembley Park or Wembley Central and not Park Royal at all.
