In "Taken", where he's talking to the kidnapper about his daughter. "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."
Roy Batty's tears in rain speech from the movie Blade Runner.<br />
"I've... seen things you people wouldn't believe... Attack ships on fire off the shoulder of Orion. I watched c-beams glitter in the dark near the Tannhäuser Gate. All those... moments... will be lost in time, like tears... in... rain. Time... to die"
Virginia Woolf's breakdown at the railway station in the film "The Hours". Every time I see it, I could shout with her: "I am dying in this town!"
One of my favorites is the Prologues scene of The LIbertine with Johnny Depp. The speech is simply fantastic
