Kelly Macdonald: Diane
Mark "Rent-boy" Renton : Excuse me, excuse me. I don't mean to harass you, but I was very impressed with the capable and stylish manner in which you dealt with that situation. And I was thinking to myself, now this girl's special.
Diane : Thanks.
Mark "Rent-boy" Renton : What's your name?
Diane : Diane.
Mark "Rent-boy" Renton : And where are you going, Diane?
Diane : I'm going home.
Mark "Rent-boy" Renton : Well, where's that?
Diane : It's where I live.
Mark "Rent-boy" Renton : Great.
Diane : What?
Mark "Rent-boy" Renton : Well, I'll come back with you if you like, but like, I'm not promising anything, you know.
Diane : Do you find that this approach usually works? Or let me guess, you've never tried it before. In fact, you don't normally approach girls - am I right? The truth is that you're a quiet sensitive type but, if I'm prepared to take a chance, I might just get to know the inner you: witty, adventurous, passionate, loving, loyal. Taxi! A little bit crazy, a little bit bad. But hey - don't us girls just love that?
Mark "Rent-boy" Renton : Eh?
Diane : Well, what's wrong boy - cat got your tongue?
Diane : You're not getting any younger, Mark. The world's changing. Music's changing. Even drugs are changing. You can't stay in here all day dreaming about heroin and Ziggy Pop.
Mark "Rent-boy" Renton : It's Iggy Pop.
Diane : Whatever. I mean, the guy's dead anyway.
Mark "Rent-boy" Renton : Iggy Pop's not dead. He toured last year! Tommy went to see him.
Diane : The point is, you've got to find something new.
Diane : [Mark has spent the previous night having sex with Diane only to realize she was an underage schoolgirl] Well, what's the matter, Mark?
Mark "Rent-boy" Renton : It's you that's what's wrong!
Diane : Well at least us hold hands.
Mark "Rent-boy" Renton : No, we're not holding hands!
Diane : No? But you seemed a lot more happy to do more last night. There's nothing wrong with it.
Mark "Rent-boy" Renton : Its illegal that's what's wrong with it! You know what they do to people like me in prison? They cut your balls off and flush them down the toilet.
Diane : Calm down; you're not going to prison.
Mark "Rent-boy" Renton : That's very easy for you to say Diane!
Diane : Can I see you again?
Mark "Rent-boy" Renton : [scoffs] Certainly not!
Diane : If you don't see me again, I'll tell the police.
Mark "Rent-boy" Renton : [turns around and stares at Diane blankly]
Diane : I'll see you around then.
