Continuity mistake: During the end car chase when Brian's daughter is driving the taxi, she keeps crashing into things, yet in the shots of the taxi after there is not damage whatsoever.
Continuity mistake: Bryan is cornered in an Istanbul alley and engages in fierce hand-to-hand combat with Albanian gangsters. Bryan takes one of the gangsters hostage, holds a gun to the gangster's face and threatens to kill him. Another gangster doesn't even hesitate to shoot Bryan's hostage in the back multiple times, and the guy drops down dead at Bryan's feet. Bryan is frozen on the spot. Camera cuts to another Albanian gangster entering the alley, holding Lenore hostage. Camera cuts to close up of Bryan, who quickly calls his daughter Kim to warn her. Camera cuts back to a full view of the alley, and the dead guy at Bryan's feet has completely vanished.
Continuity mistake: In the scene where Kim Mills steals a Mercedes w124 taxi and drives her dad with it to the House where her Mum is being held hostage, you can see that it is actually 2 different w124 models that are being used. (though with similar number plates). Also in the subsequent chase scenes, the camera also alternates between the two taxis.
Factual error: Bryan tells Kim to go to the US Embassy if he doesn't return in 5 minutes, and enters "US Embassy" into the GPS. Later there is a chase scene that ends at a building with "United States Embassy" on the signage. This is impossible unless they drove about 6 hours to Ankara, the capital city. Istanbul has only a US Consulate (albeit a very impressive one).
Factual error: In the end credits, when the list of songs appears, look at the credit for Alex Clare's song "Too Close". His name is misspelled as Alex Claire, a very noticeable typo.
Other mistake: During the first chase scene in the movie about 10 seconds after the man on a moped is knocked over you can see through the car's back window that a woman is walking at the same speed as the speeding car.
Continuity mistake: When Bryan is invited inside for a drink, his ex-wife takes a bottle of wine to the table in the kitchen. The wine glasses then are magically filled.
