The Avengers

& Fury: How bad is it?
    Phil Coulson: That’s the problem, sir. We don’t know.

& Fury: We have no quarrel with your people.
    Loki: An ant has no quarrel with a boot.

& Captain America: War isn’t won by sentiment, Director.
    Fury: No, it’s won by soldiers.

& Captain America: We have orders, we should follow them.
    Iron Man: Following’s not really my style.
    Captain America: And you’re all about style, aren’t you?
    Iron Man: Of the people in this room, which one is A — wearing a spangly outfit and B — not of use?

& Iron Man: It’s good to meet you, Dr. Banner. Your work on anti-electron collisions is unparalleled. And I’m a huge fan of the way you lose control and turn into an enormous green rage monster.

& Captain America: Stark, we need a plan of attack!
    Iron Man: I have a plan: attack!

& Black Widow: I don’t see how I can. These guys come from legend. They’re basically gods.
    Captain America: There’s only one God, ma’am. And I’m pretty sure he doesn’t dress like that.

& Guard: Are you an alien?
    Banner: What?
    Guard: From outer space, an alien.
    Banner: No.
    Guard: Well then son, you’ve got a condition.

& Loki: I have an army.
    Iron Man: We have a Hulk.

& Captain America: Dr. Banner... now might be a really good time for you to get angry.
    Hulk: That’s my secret, Cap. I’m always angry.
