As a fanboy myself, one of the fun things about the gig has been every time I get a new script, I get to find out more about his day - to-day life and what goes on and what his relationships are.

What I think is incredible about what Marvel has done and with Jon Favreau I think really maybe helped come up with, is what the template is.

I don't think Aaron Sorkin can write a character who isn't really funny.

When I was backstage at Comic-Con, about to go out and do the panel for Thor, and Joss Whedon ran up and introduced himself, I already almost passed out, right then. And then, he said, "I've been meaning to call you. You have a big part in The Avengers. Can we introduce you as part of the cast?" It was pretty Make-A-Wish Foundation. I was pretty sure I was dying and nobody had told me yet.

I guess what we know about the Avengers is there's a reason why all of the heroes that we've been meeting, from Thor to Captain America - everybody - they need to work together.

One thing I've learned about the Marvel universe is that it's a little bit like God... if you want to make him laugh, just make a plan.

I'm not in Captain America because it takes place in the '40s. Both he and Bruce Banner are relationships that evolve during this - two more rock stars that I got to get on stage, ready to play ball.
