I have three:
"You built a time machine, out of a DeLorean?" - Marty McFly from Back to the Future
"When Gotham is ashes... then you have my permission to die." - Bane from The Dark Knight Rises
"Oh, you think darkness is your ally. You merely adopted the dark. I was born in it, molded by it. I didn’t see the light until I was already a man. By then, it was nothing to me but blinding! [Batman attacks Bane but is easily overcome] The shadows betray you because they belong to me." - Bane from The Dark Knight Rises
