Continuity: When the duped Egyptian architect realises he is in danger and flees to his car, the first camera tracks him to the vehicle and an object of some kind - a plastic bag or piece of cardboard - is visible under the front of his car. It is gone in the next scene.

Factual error: In the first scenes of the movie, when the SWAT team raids the house of terror suspects in the UK, the tactical team waits to move in until a passenger train passes by the neighborhood. The train is an Amtrak train and not the type of passenger train that runs in the United Kingdom.

Factual error: When the predator drone follows the caravan of cars, the sand storm they cause blocks the view of the vehicles. In reality the drone's camera would switch to infra red and the sandstorm would be pointless.

Factual error: When Leonardo DiCaprio is arriving on the tarmac at what is supposed to be Abu Dhabi, the main (and very distinctive) Dulles airport terminal is visible in the background.

Deliberate "mistake": The helicopter camera shot of buildings under construction in Dubai plays backwards, to achieve a better effect. It's given away by the traffic on the ground traveling backwards, trucks make this particularly obvious.

Factual error: In the first scenes, when US Soldiers are attacked, the EOTech Aiming Device on one soldiers Rifle is mounted backward, e.g. looking towards the soldier, not the enemy.
