I need to react to a script, to feel strongly about it in some way. And I need it to be a complex character for sure. And also, I think a lot about what kind of audience there is for the film, what they're looking for and ways to connect with them in the playing of a character.

Why I'm so stimulated by [producing] is it becomes more proactive. Instead of waiting around for a script to come in, or some movie trying to go. You're waiting around always for that opportunity, which is great, but I like to be a little bit more proactive. I'm a very action-oriented guy - I'm a doer. The company really became this spearhead for that sort of attitude, and so that, to me, was the most exciting part of it.

Architecture and building is about how you get around the obstacles that are presented to you. That sometimes determines how successful you'll be: How good are you at going around obstacles?

I think that'll always be there for [Clint] Barton, right? You have real life, and then you have fight life. And that's the character that I love now - discovering that in him makes him a very sort of accessible Avenger. That'll always be there, I'm sure. And it certainly plays in this one.

I want to be a good human being.

I was very shy when I was younger. But I did have a terrible temperament. I would get angry very quickly, but the rest of the time I was this big goofball, playing the drums in a band and making out with girls.

I love music. I do play. It's like mathematics, and it's also emotional. It's nice to play, for no other reason than just to play.
