I was a football player at college and dislocated my thumb. I was out for a bit and passed the theatre and saw some lovely drama students walking into an audition for 'Much Ado About Nothing' and thought: 'That's what I'll do when I recover.' I joined that production and was hooked.

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.

As you can imagine when you have to summon a force like that together, the opposing elements are pretty freaking gnarly. I would think of those pioneer movies where they've got the cook and the ladies loading the guns and firing at the surrounded wagons. I don't put Coulson in that category, I think he is on the upper tier of people who come to scrap at situations like that but everybody's involved.

You can never discount the pleasure of showing up to work with Scarlett Johansson and now Cobie Smulders. That's just a day that's easy on your eyes.

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

But what I've also really liked about it is that it not only has Marvel set about... if they just were slavishly trying to bring the comic books to life, literally, I don't the movies would work, because it's different to see something on screen in three dimensions with actors, and they kind of, I believe, are constantly trying to find a way to absolutely respect the source material and at the same time, transform it into something that works and that you believe on screen.
