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.
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.
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: Bryan's daughter Kim has an iPhone - when you see the phone she has no signal, but is able to make calls from the phone. This happens twice.
Continuity mistake: When Kim leaves the hotel pool to return to her room she leaves behind her iPad on the lounger. When the gang members come looking for her at the pool her iPad is not on the lounger anymore.
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.
