Character mistake: The news reporter at the start of the film states an autopsy will take place in the next 48 hours. British reporters use the terminology "Post Mortem" not autopsy. (00:09:50)
Other mistake: Colin Salmon in Box Command introduces himself to Banning as Chief Inspector. However, the rank on his shirt is of a Commander rank.
Factual error: London is shown to use the two-tone air raid siren to warn Londoners of the danger. The problem is, these sirens were decommissioned in 1992 following the end of the Cold War. (00:51:50)
Factual error: Throughout the Helicopter scene they are referred to as Marine One, Marine Two and Marine Three. There is a couple of problems with this. Marine One is correct as it has the President on board. Marine Two only has this call sign when the Vice President is on board, which he is not. And finally, there is no Marine Three call sign. (00:36:10)
Factual error: When the president arrives at the church, he gets out of the limousine, and they close the door. The Secret Service keeps it open for emergencies. The church door also gets closed, same issue. An agent would be there keeping it open. Then the entire motorcade is missing including the second limousine which is always present.
Continuity mistake: Secretary of Defence has her name spelt as "MacMillan" instead of "McMillan" (00:35:00)
Factual error: Marine One should have rushed directly to a warship on the water. The navy would have had many of them on alert well before, and Marine One would have had a pre-planned escape route secured by fighter jets.
Factual error: In such an insecure situation, the SS would have arranged a secure bunker ahead of time for VIPs on site. There is no mention of it.
Factual error: During the attack on the President at the church, where is the rest of the motorcade? The second limousine, several SS armored SUVs and the entire Counter Assault Team are missing.
Factual error: During the fight scene in the London underground, it's suppose to take place at Charing Cross station. Charing Cross is on the Northern Line and the Bakerloo Line. If you look at the map in the background that list the stations, none of them make sense. Green Park, Bond St and Baker Street are not on either of those lines, they are on the Jubilee. They skipped quite a few stations as well on the Jubilee. They picked random stations and made a map. (00:00:48)
Revealing mistake: When Mike is throwing Bakari around and starts his speech, pay close attention to Bakari's shirt. The padding is visible underneath it in some shots. (01:17:30)
Revealing mistake: When Bakari is fighting Banning with the machete, the blade gets stuck in some metal bars. In this shot you can see a break line visible in the blade where it snaps a few seconds later. (01:17:00)
Continuity mistake: Throughout the 4x4 chase scene the bullet holes in the windscreen keep changing place. (00:29:10)
Revealing mistake: During the live stream, the second punch that the president receives misses him. However, he reacts to the punch. (01:15:50)
Factual error: The rescue team at the MI6 safehouse takes ages to arrive. A spec-ops team with helicopters should have been on alert and arrived in minutes.
Deliberate mistake: Where are the motorcades for the other world leaders?
Plot hole: They find the terrorists by the electricity they're using, but they're using generators, off the grid.
Other mistake: There has been a major terror attack on London. Explosions big enough to send shockwaves across the capitol, and yet people can be seen walking about as if nothing has happened. (00:29:00)
Character mistake: When the Vice President has worked out Banning's signal he says "All right Manning" instead of Banning. (00:48:50)
Suggested correction: I hear him say "Banning."
Factual error: Air Force One has landed. The caption reads: "Stansted airport, 20 miles north of London." it's closer to seventy miles. They probably wanted to get to the city quicker. (00:17:20)
Suggested correction: It's 38 miles to drive down the M11 from Stansted to St Paul's cathedral - and about 20 as the crow flies.
