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)
Other mistake: The agent infiltrates Barkawi's daughter's wedding and sends a message to the US military to bomb the place remotely. On the agent's phone he types "Barkawi on sight" and clicks send, but there is no phone number or contact. (00:04:30)
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)
Character mistake: When Mike is watching a news report about the Prime Minister's death, a British reporter uses the American pronunciation of "schedule." Not something that happens on British news channels. (00:09:50)
Continuity mistake: When Mike is telling the President the route to the chapel, it is a close up and when Mike says "It's a cluster ****" the president is looking at him nodding, but it then cuts to behind Lynne Jacob's and he is staring at the map. (00:12:50)
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.
Continuity mistake: When the US President gets to London and gets out from the chopper, the sun changes between shots. (00:19:10)
Factual error: When the President is getting out of his car, we see the thin doors, like any usual car. However, in reality, Cadillac One has thick doors that weigh as much a Boeing 757 door. Not to mention the vulnerability of the car used in the movie. There's a reason why the Cadillac One is nicknamed "the beast." (00:23:10)
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)
Continuity mistake: Throughout the 4x4 chase scene the bullet holes in the windscreen keep changing place. (00:29:10)
Plot hole: After an assault on the scale that's been witnessed, covering a wide area of London by extremely well prepared attackers, there's no way Marine 1 would fly to the airport at low altitude within easy range of missiles, and then when attacked, double back over the areas that have already been attacked where hostiles would still be present. (00:35:00)
Continuity mistake: Secretary of Defence has her name spelt as "MacMillan" instead of "McMillan" (00:35:00)
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 they spot the guy with the missile from the helicopter, the pilot says "we're being pinged", and Banning says "stingers." Stinger missiles are infra-red seeking, passively tracking the heat of a target, so there's no way to know if you're being tracked by one or not. As a highly-trained secret service agent, he'd know that. (00:36:50)
Continuity mistake: When the helicopter has crashed and the President and Banning are standing outside, Banning removes his radio and earpiece and throws them to the ground. The earpiece is back in the next shot. (00:40:00)
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: 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)
Character mistake: When Mike and the SAS team leader first meet, the team leader introduces himself as Will Davis, Captain. However at the near end when they say goodbye to each other, Mike addresses him as Lieutenant. (01:07:35 - 01:25:35)
Revealing mistake: During the live stream, the second punch that the president receives misses him. However, he reacts to the punch. (01:15:50)
Continuity mistake: When Banning fights three terrorists when the lights come back on, the 3rd gunman's gun changes from a rifle to a sub. (01:16:35)
