- Cus D'Amato: What's the difference between the hero and the coward? There ain't no difference. They both feel exactly the same on the inside: they both fear dying and getting hurt. It's what the hero does that makes him a hero. And what the other doesn't do, makes him a coward.

- Mike Tyson: I was just a kid when I first got to see Muhammad Ali. I saw the way people looked up to him, saw their smiling faces. And I said to myself 'That's what I wanna be, I wanna be champ of the world'.
- Man in the gym: Tyson versus Spinks, biggest purse in the history of boxing, two weeks away. Right? The other night I saw Don King shaking hands with Donald Trump. I mean, can you imagine - King and Trump shaking on a deal? It's gonna take a dozen accountants to figure out who's the screw-er and who's the screw-ee!
- Cus D'Amato: [to a young Mike Tyson] Don't be scared of going into a fight, it's when you're AIN'T scared, that's the time to worry, because fear is the friend of every good and reasonable athlete.
- Don King: Mike, for future reference: never, under no circumstance, never call a colored woman the C word.
- Cus D'Amato: You allow yourself to be distracted, you allow yourself to fail. Everybody get back to your work.
- Kevin Rooney: Hey, you know what's going to happen if you lose tonight? Do ya? That little girlfriend of yours is gonna go home and fuck right over there and she's gonna do all kinds of nasty things all night long with him. And you know why? Because she's here...
- Mike Tyson: Fuck you!
- Kevin Rooney: Because she's here for the champ. She's ain't here for Iron Mike. She's here for the champ. And she don't care what the fuck his name is so long as people call him champ.
- Robin Givens: You think I've been fucking Donald Trump? I have NOT been fucking Donald Trump! FUCK YOU!
