Ted Heinkin inaccurately places the city of Beirut in Darfur when informing President Ashton of the leader of the group suspected of threatening the President. Beirut is the capital city of Lebanon, and Darfur is a region in Sudan.
During Enrique's section, he escapes the police foot chase. After checking his pistol's magazine, he loads the pistol and cocks the hammer before confronting someone unseen. Later in the movie, from Howard Lewis' point of view, Enrique puts the un-cocked pistol in his rear waistband before stepping out to confront the unseen individual.
When Kent Taylor is being shot at while driving, he is sitting on the right (through the windscreen). Just before he swerves into the concrete, before he realizes he is going to crash, he is on the left of the car (through the windscreen).
Several cars keep re-appearing during the chase scenes, including: a red Peugeot 306 sedan, a white Nissan Platina (which is not sold in Europe), an orange Opel Corsa, and a red Volkswagen Golf (Rabbit).
The first time at the Plaza, when Barnes is reviewing the footage, Taylor asks "You saw the shooter?" to which he replies, "No ... I saw a flash of light". The second time at the Plaza, when asked the same question, he just says "I saw a flash of light".
At one point, right after the cars drive down the stairs, two brand tags are visible on the seat belts in Barnes' car mirror, which means a stunt driver is driving the car. During the rest of the chase, Barnes is not wearing a seat belt.
In the ending scene, the helicopter in the colours of "Marine 1", is a VH-72 Kestrel, a variant of the Agusta Westland Merlin. Although this variant of this helicopter was developed for use as U.S. presidential transport, the project was cancelled and the U.S. Marine Corps continue to use the VH-3D Sea King and VH-60H Whitehawk helicopters for presidential transport.
The police cars and the blue Astra have Chevrolet badges on their grills. In Europe, they would have Opel badges (except in the UK, where they would have Vauxhall badges). GM owns Vauxhall, Opel, and Chevrolet.
Incorrect translation into Spanish. When the suicide bomber is told, "You will make us proud," (from the subtitles in English) what the character actually says is, "You will make us our pride." (Nos hará nuestro orgullo.)
Several North American vehicles appear in chase scenes, including Ford Escorts and Focuses (which are common in Spain). The emergency vehicles are Chevys and Freightliners, neither of which are sold in Europe (although some Chevy ambulances exist throughout Europe).
Agent Barnes is on his cell phone when he steals the blue Astra from a Spaniard. As he gets in the car, the camera shows a clutch pedal and a gas pedal. Barnes shifts the car into first gear, talks on his phone, and drives for about 40 seconds without shifting out of first gear.
The timing of the two explosions changes during Enrique's section. When he is led away by Secret Service, the agent handling Enrique is momentary distracted by the distant explosion at the hotel. Enrique punches the agent, and the podium explodes seconds after the first bomb. In every other portrayal, the first bomb explodes well before the one under the podium. Barnes and Taylor talk to Lewis, and Barnes reviews the video that Lewis shot while Taylor makes it to the 3rd floor of the plaza, in the time it took Enrique to throw a single punch.
