Marvel's The Avengers2012

Thor:
You speak of control, yet you court chaos.

Bruce Banner:
That's his MO, isn't it? I mean, what are we, a team? No, no, no. We're a chemical mixture that makes chaos. We're ... we're a time-bomb.

Nick Fury:
You need to step away.

Tony Stark:
Why shouldn't the guy let off a little steam?

Steve:
You know dang well why! Back off!

Tony:
I'm starting to want you to make me.

Steve:
Yeah. Big man in a suit of armor. Take that off, what are you?

Tony:
Genius. Billionaire. Playboy. Philanthropist. [Natasha shrugs condescendingly, but concedes Stark's point]

Steve:
I know guys with none of that worth ten of you. I've seen the footage. The only thing you really fight for is yourself. You're not the guy to make the sacrifice play, to lay down on a wire and let the other guy crawl over you.

Tony:
I think I would just cut the wire.

Steve:
Always a way out. You know, you may not be a threat, but you better stop pretending to be a hero.

Tony:
A hero? Like you? You're a laboratory experiment, Rogers. Everything special about you came out of a bottle.

Steve:
[enraged] Put on your Supersuit. Let's go a few rounds.
