Continuity mistake: When Kim is kidnapped, she describes the man "Beard. Six feet. Tattoo right hand, moon and star." When Bryan listens to the tape in the jet, she says, "Mustache. Six feet. Tattoo on right hand, moon and star. Dad!"
Continuity mistake: In the scene when he is driving his daughter to the airport before she flies to France, it appears they are riding inside a late model BMW 5-Series. This is apparent by the tan leather interior and the double adjustable padded headrests and rear seat headrests. However, when they appear at the airport terminal, he is seen unloading the luggage from his personal car, a 2005 Nissan Sentra GXE with a basic gray cloth economy interior (Confirmed by the Features on the DVD release)
Bryan: I don't know who you are. I don't know what you want. If you are looking for ransom, I can tell you I don't have money. But what I do have is a very particular set of skills; skills I have acquired over a very long career. Skills that make me a nightmare for people like you. If you let my daughter go now, that'll be the end of it. I will not look for you, I will not pursue you. But if you don't, I will look for you, I will find you, and I will kill you.
Bryan: I was told I have 96 hours. That was sixteen hours ago.
Jean Claude: Okay, first we should find the spotter.
Bryan: I found him. He's dead.
Jean Claude: You found him that way? Bryan, you cannot just run around, tearing down Paris.
Bryan: Jean Claude, I will tear down the Eiffel Tower if I have to.
