Marion Cotillard: Mal
Mal : We'd be together forever. You promised me.
Cobb : I know. But we can't. And I'm sorry.
Mal : You remember when you asked me to marry you? You said you dreamt that we'd grow old together.
Cobb : But we did. We did. You don't remember?... I miss you more than I can bear, but... we had our time together. And I have to let go... I have to let you go.
Cobb : I can't stay with her anymore because she doesn't exist.
Mal : I'm the only thing you do believe in anymore.
Cobb : I wish. I wish more than anything. But I can't imagine you with all your complexity, all you perfection, all your imperfection. Look at you. You are just a shade of my real wife. You're the best I can do; but I'm sorry, you are just not good enough.
Mal : I'll tell you a riddle. 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. But it doesn't matter. How can it not matter to you where that train will take you?
Mal : [Sitting on the ledge, to Cobb] I'm asking you to take a leap of faith.
Cobb : No I can't. You know I can't do that. Take a second, think about our children. Think about James. Think about Phillipa now.
Mal : If I go without you they'll take them away anyways.
Cobb : What does that mean?
Mal : I filed a letter with our attourney explaining how I'm fearful for my safety. How you've threatened to kill me.
Cobb : Why did you do that?
Mal : I love you, Dom.
Cobb : Why did you... why-why would you do that?
Mal : I freed you from the guilt of choosing to leave them. We're going home to our real children.
Cobb : No, no, no, no. Mal you listen to me, alright? Mal look at me, please.
Mal : [Closing her eyes] You're waiting for a train...
Cobb : Mal, goddammit! Don't do this!
Mal : A train that will take you far away...
Cobb : James and Phillipa are waiting!
Mal : You know where you hope this train will take you...
Cobb : They're waiting for us!
Mal : But you can't know for sure...
Cobb : Mal, look at me!
Mal : Yet it doesn't matter...
Cobb : Mal, goddammit!
Mal : Because you'll be together.
Cobb : Sweetheart! Look at me!
Mal : [Jumps off of the ledge]
Cobb : Mal, no! Jesus Christ!
Mal : What are you doing here?
Ariadne : My name is...
Mal : I know who you are. What are you doing here?
Ariadne : I'm just trying to understand...
Mal : How could you understand? Do you know what it is to be a lover? To be half of a whole?
Ariadne : No...
Mal : I'll tell you a riddle. 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. But it doesn't matter. How can it not matter to you where that train will take you?
Cobb : Because you'll be together.
Mal : Do you know what it is to be a lover? Half of a whole?
Mal : No creeping doubts? Not feeling persecuted, Dom? Chased around the globe by anonymous corporations and police forces, the way the projections persecute the dreamer? Admit it: you don't believe in one reality anymore. So choose. Choose to be here. Choose me.
Mal : Your world is not real!
[as the dream collapses]
Mal : [to Saito, handing him his secrets] He was close. Very close.
Mal : ...and judging by the decor, we're in your mind, aren't we, Arthur?
Mal : 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.
