Some of Sin City's most hard-boiled citizens cross paths with a few of its more reviled inhabitants.

[from trailer]
Johnny: Sin City's where you go in with your eyes open, or you don't come out at all.
Marv: [observes Ava] That right there is a dame to kill for...
Nancy Callahan: Looks like trouble.
Marv: Looks like Christmas.
Marv: [takes a punch] Just another Saturday night...
Mort: You keep asking for it, and asking for it!
Bertha: [as Johnny turns to leave] Hey, wait! Look, you seem like a nice guy and you remind me of an old boyfriend, alright? Here.
[She offers him one dollar]
Bertha: It won't get you very far.
Johnny: [taking the money] Honey, this'll take me to the moon.
John Hartigan: Death is just like life in Sin City. It always wins.
Dwight McCarthy: Never lose control. Never let the monster out.
Marv: [waking up next to a crashed car and a group of dead bodies] How did I get here? What have I done?
Marv: [seeing Nancy covered in scars] Just give me a name.
[long pause]
Nancy Callahan: ...Roark.
Dwight McCarthy: Nobody's killing anybody. Not while I'm around.
Nancy Callahan: You're the only man I ever loved.
John Hartigan: No one ever really guessed what hell is. It's watching the people you love, in pain.
Ava Lord: You've made me a very rich woman.
Dwight McCarthy: [getting beaten by Manute] An atom bomb goes off between my legs.
Johnny: You'd be smart to kill me now.
[last lines]
Nancy Callahan: This rotten town... It soils everybody.
Ava Lord: What does it feel like?
Dwight McCarthy: What?
Ava Lord: Murdering an innocent man. Just wanna know what it felt like. Must have been beautiful.
Dwight McCarthy: What are you talking about innocence?
Ava Lord: I knew I could count on you. Sex always made you stupid, ready to believe anything.
[chuckles]
Ava Lord: You've just made me a very rich woman.
[points a gun at Dwight]
Ava Lord: Do me one last favor, lover? Stay still long enough for me to blow your brains out.
Wallenquist: You're starting a gang war. And the gang are professionals.
[first lines]
Marv: Metal screams. Something hits me square in the chest. There's no up or down. I don't weigh a thing.
Marv: [to Dwight] Here we are pal. All of sudden this doesn't look like the brightest idea you ever had, huh?
Marv: Why'd he call me "Bernie"?
Dwight McCarthy: She owns me. Body and soul.
[pointing a gun at Sally]
Joey: You're gonna suck me dry, and you'll never ever stop!
Nancy Callahan: And this one's for John Hartigan, fucker!
[shoots]
Dwight McCarthy: This time they've crossed a fatal line.
Marv: How did I get here? What have I done, and why? I can't remember for the life of me.
Senator Roark: [poker scene] I favored your mother, she was a whore, and not a very good one.
Johnny: She was an angel.
Johnny:
Senator Roark:
Senator Roark: [shows: Four Kings]
Johnny: [shows: Four Aces]
Johnny: See, I told you, I never lose.
Johnny: I beat you, twice. That means I'm better than you are, and everybody knows it because I beat you again. Every time somebody tells this story - and they'll all say they won't tell it but they will - That's the story that will be told, again and again until you're dead... and after you're dead. I beat you forever.
Johnny: And they all know what happens when you do.
Senator Roark: [pulls out gun] Say hello to your mama. She always was a stupid bitch.
[shoots Johnny in the center of his forehead]
Senator Roark: If I could give any young man advice it'd be this: Always wear a rubber.
Senator Roark: Now take out the trash! Let's get back to the game!
Senator Roark: Now, who wants to play?
Ava Lord: I own Sin City.
Gail: You have ten seconds to tell us what your doing bringing COPS to Old Town!
John Hartigan: Don't avenge me, Nancy. It'll be the death of you.
Dwight McCarthy: Ava...
[gets shot out of window]
Ava Lord: [looks out window and sees that he is still alive] Damn.
[repeated line]
Dwight McCarthy: Ava. Damn.
Dwight McCarthy: You're insane.
Ava Lord: No, Dwight. A crazy person would be anyone who belives me. And that would be you.
Manute: You'll have to beat the goddess.
Dwight McCarthy: She's no goddess. She's a monster.
Johnny: You'd be smart to kill me now.
Senator Roark: [laughs] I'll do far worse than kill you boy.
John Hartigan: Let's tear him to pieces.
[last lines]
Nancy Callahan: This rotten town, it swells everybody.
Senator Roark: I'm holding a gun on you, young lady. The rules are, you pretend there's a chance I *won't* shoot you.
Senator Roark: Power is a fragile thing. It tolerates no threat. Defiance must be met with an example of the wages of defiance.
[thugs maim his hands]
Johnny: You'd be smart to kill me now.
Senator Roark: I'll do far worse than kill you.
Sally: Kill him! Kill him! Kill him!
Dwight McCarthy: [stops punching Joey] Nobody's killing anyone.
Sally: Then can I have a ride?
Marv: Remember when you did, remember what you did.
[from the movie on Nancy's television]
Sam: You shot me in the gut.
Sam's Friend: It wasn't me, Sam. It was the babe.
Sam: This rotten town... it soils everybody it touches.
Kroenig: [injecting his arm with heroin] Steady as a rock.
Marv: What have I done, and why? I must have forgotten my medicine. I've got a condition. It's bad to forget your medicine when you've got a condition.
Dwight McCarthy: I've taken a beating before, but never anything like this. Never like this.
[punch echoes]
Dwight McCarthy: The sounds go wet. Maybe he keeps hitting me, I don't know. I'm gone. Gone to that place where there's no pain or thought. I wake up in mid air. The pavement rushes up to give me a big sloppy kiss.
Senator Roark: Power is as power does.
Marcie: We're we goin', Johnny?
Johnny: Everywhere.
Johnny: I'm ready for your worst.
Senator Roark: Boy, you don't even want to dream about my worst.
