Poster text: I don't know who you are. But if you don't let my daughter go, I will find you... I will kill you. Actual movie quote: 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 are 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.

Rade Serbedzija is a Croatian Serb and plays an Albanian in the sequel.

Money, Dear Boy: Liam Neeson didn't really care about the first film and only took the job because he thought it was a Direct to Video film and would be a quick paycheck. His fee went up considerably for the sequels when he realized he had a franchise on his hands and he was paid 20 million dollars to play Bryan again in Taken 3.
