Factual error: The movie was supposed to be in Salamanca, Spain, but was shot in Mexico City and Puebla, Mexico. There are constant landmarks that are easily pointed out if you have ever been to Mexico City. Best example: the metro is that of Mexico City. Salamanca doesn't even have a metro. The square where the president is speaking is actually two different locations. The one shot from above is Salamanca but the one close up is from of a museum in Mexico City. You can easily tell these two apart. The tunnel that the president is taken under so he can get into the hotel secretly is a tunnel under the anthropology museum in Mexico City. The chase scene is shot in the streets of Mexico City and Puebla's main square. The green taxi Beetles that are famous in Mexico City can be seen as well, as can the small buses known as "paseros" that are used as public transportation. There are many others as well. One shot of the chase scene was shot on the street I lived on in Mexico City. I watched the whole thing over a five day period.
Continuity mistake: This movie has a lot of problems with VWs. During the car chase, the blue car passes the red older 80's VW three times between shots. Later in the film, a blue VW rams into the turned over ambulance and in a later shot it is away from the ambulance and undamaged. In another part of the chase scene, the police car passes another blue VW two times.
Character mistake: At the end of the film, the newscaster comments that the lone assassin has been killed, but the ticker beneath him reads "Lone assassin arrested."
Other mistake: When Barnes first gets into the Chevrolet Astra (blue car), he pursues the police car but never changes from first gear, as he has one hand on the steering wheel and the other holding his phone to his ear. Without a gear change he'd never reach chase speeds, plus the engine strain would be easily heard.
Continuity mistake: When the president is abducted in the ambulance there is a shot of him waking up. In the close-up of his face as he awakes, the metal nose clamps on his plastic oxygen mask are sticking straight out; when the camera angle changes the metal flaps are clamped down on his nose.
Other mistake: When the Secret Service agents are running after the Spanish cop, they are running and shouting with their weapons waving in the air, yet the group of Spanish police that they pass don't try to challenge them.
Character mistake: At the end of the movie the reporter says the lone assassin was shot and killed but the banner at the bottom says the lone assassin was arrested.
Character mistake: While talking to President Ashton, Phil McCollough comments, "We're looking for five people out of six million." Salamanca's population is only about 160,000.
Plot hole: It stretches credibility that the little girl wanders quite far away from the plaza and ends up on a busy road, and her mother just happens to be nearby.
Suggested correction: Anna wasn't following her mother. Her mother got separated from her in the chaos and when Howard carried her to safety, she saw a woman who resembled her mother leaving the plaza. She then ran in the general direction of the woman and it just so happened to be the same direction that Howard was running and ended up in.
Also, it isn't entirely out of the realm that her mother ran in the same direction as them both prior to Anna seeing her since she was out of the plaza before Anna and Howard were.
