Inception

"Written and directed by Christopher Nolan."

"Downward is the only way forward."

"An idea is like a virus. Resilient. Highly contagious. And even the smallest seed of an idea can grow. It can grow to define or destroy you."

"Dreams feel real while we're in them. It's only when we wake up that we realize something was actually strange."

"You're waiting for a train. A train that will take you far away. You know where you hope this train will take you, but you don't know for sure. Yet it doesn't matter, because we'll be together."

"Your condescension, as always, is much appreciated, Arthur."

"Cobb: Ah, no use threatening him in a dream, right, Mal?"

"Mal: That depends on what you're threatening. Killing him will just wake him up. But pain – [suddenly shoots Arthur in the knee] Pain is in the mind. And judging by the decor, we're in your mind, aren't we, Arthur?"
