Factual error: The film is meant to be set in the US, but towards the very end of the film where Clay Banning is talking to Mike's wife, behind him there is a British plug socket on the wall at the bottom of the stairs.
Factual error: As Mike is turning into hospital in the Ford Explorer it's clear the film was shot in Europe because all the other vehicles especially FH Volvo trucks (which don't exist in the US) were European.
Factual error: When the President travels anywhere, there is either a "hard car" or a secure bunker in the immediate vicinity in case of an emergency. There is no armoured vehicle in the fishing scene and no bunker at the hospital.
