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.
Question: Can we assume that Brian or Stuart had Amanda's body shipped back to the U.S.?
Answer: It's never made clear, but that would be the logical assumption. It's possible that the other Albanians had already disposed of Amanda's body before the police got to the house. After rescuing Kim, Brian likely cooperated with the French authorities regarding the sex slave operation and would have attempted to locate Amanda's remains and also make sure arrangements were made for the other girl he rescued.
Question: What would have eventually happened to Marko after Bryan left him in the basement? Would he just have died and continued to have current surge through him till someone found him? Would he eventually burst in to flames? Would his heart explode? I know he dies, that much is obvious. Just curious as to what happens in the longer term.
Answer: Depends on how much current is actually running through him. Since it didn't kill him right away, even after a few jolts to get him to talk, it's unlikely it was enough that he would ever burst into flames or that his heart would explode. Most likely, he just slowly cooked until he dried up and burnt like a turkey left too long in the oven.
