When Marvel put together Ultimate Spider-Man and someone came up with the idea of having Principal Coulson, they said, "Do you want to do the voice?" I thought, "I have to do the voice!" Because I have a daughter and we watch some cartoons, I couldn't bear the idea of tuning in and hearing somebody else's voice.

No matter how tight the shot is, if I'm narrating it too much, there's a barrier between you and the experience, because the process of reading a book, or watching a movie, or watching a play is that you're watching a dream.

Sometimes you can do Shakespeare and you're still not an actor.

There's very few people, who really thrive creatively under great stress and conflict.

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.

There's always changes in the way they do that in the cinematic universe. I think, with the S.H.I.E.L.D. 2.0, you're seeing some of the first ripples of those different points of view on what S.H.I.E.L.D. should be when it's rebuilt. I'm very, very curious to know which side Coulson will end up on in that struggle.

The tremendous Jeremy Latcham from Marvel showed up with this one-of-a-kind animated encyclopedia about S.H.I.E.L.D. and The Avengers. Coulson wasn't a part of the comic books, which is a singular thing about him that I thought would get me killed off very quickly, but luckily, it didn't. It just became a thing that I fit into, and they kept finding new and better uses for me.
