Inception (2010)

Cobb: We need the heir of a major corporation to dissolve his father's empire.
Eames: Well, you see, right there you have various political motivations and anti-monopolistic sentiment and so forth, but all that stuff is at the mercy of your subjects own prejudice. What you have to do is start at the absolute basic.
Cobb: Which is what?
Eames: The relationship with the father.

Eames: You mustn't be afraid to dream a little bigger, darling.

Cobb: Why don't you take me there?
Eames: Once you've lost your tail. The man at the bar.
Cobb: Cobol Engineering. That price on my head, is that dead or alive?
Eames: Can't remember. See if he starts shooting.

Cobb: Inception. Now, before you bother me telling it's impossible...
Eames: No, it's perfectly possible, it's just bloody difficult.

Arthur: With the slightest disturbance, dreams are gonna collapse.

Cobb: I'm just doing what you taught me.
Professor: I never taught you to be a thief.

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

Cobb: What's the most resilient parasite? An idea. A single idea from the human mind can build cities. An idea can transform the world and rewrite all the rules. Which is why I have to steal it.

Cobb: Never recreate from your memory. Always imagine new places.

Cobb: We create the world of a dream. We bring a subject into that dream and they fill it with their secrets.
Ariadne: Then you break in and steal it?
