My favorites... from V for Vendetta:
"Today, however, is a day, sadly, no longer remembered. So, I thought we could mark this November the 5th by taking some time out of our daily lives to sit down and have a little chat. Of course, there are those who do not want us to speak. I suspect, even now, orders are being shouted into telephones and men with guns are racing to this station. But regardless of what weapons they try to use to effect silence, words will always retain their power. Words are the means to meaning, and for some, the annunciation of truth. And the truth is, there is something terribly wrong with this country."
"A building is a symbol, as is the act of destroying it. Symbols are given power by people. A symbol, in and of itself is powerless, but with enough people behind it, blowing up a building can change the world."
"No, what you have are bullets, and the hope that when your guns are empty I'm no longer standing, because if I am you'll all be dead before you've reloaded."
"Beneath this mask there is more than flesh. Beneath this mask there is an idea, Mr. Creedy, and ideas are bulletproof."
