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.

Because I'm stern and scolding [the characters] sometimes, I'm sure I'll get a ton of grief.

I think about it, and I realize there's been some version of a Batman or Spiderman or Superman franchise since I was a boy, since before I was a boy.

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.

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 love about Coulson is that he manages to do that and he manages to wrangle the diva superheroes, and really keep a sense of humor about it. And, you can tell that he really loves his job.

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.
