A few of my favourites:
"Cops or criminals, when you're facing a loaded gun, what's the difference?"
(Jack Costello - The Departed)
"Sometimes I wonder... will God ever forgive us for what we've done to each other? Then I look around and I realize... God left this place a long time ago."(Blood Diamond - Archer)
"Voilà! In view, a humble vaudevillian veteran, cast vicariously as both victim and villain by the vicissitudes of Fate. This visage, no mere veneer of vanity, is a vestige of the vox populi, now vacant, vanished. However, this valorous visitation of a by-gone vexation, stands vivified and has vowed to vanquish these venal and virulent vermin van-guarding vice and vouchsafing the violently vicious and voracious violation of volition." (V - V for Vendetta)
"I'm giving very serious thought.......to eating your wife" (Hannibal Lecter - Hannibal)
"This will always be the day you will remember as the day you almost.......Captain Jack Sparrow" (Jack Sparow - POTC 2)
"You were the chosen one. It was said that you would destroy the Sith, not join them. You were to bring balance to the force, not leave it in darkness." (Obi-Wan - Episode III)
