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.

With the tone of the show, like a lot of the films, the Marvel creative team has found a way to bridge really exciting stuff that has real stakes. They balance some of the action stuff that the fans of the comics really want to see with characters that people can relate to and who are very human.

There was a day on the set of Iron Man where I said, "I remember some of this stuff. I definitely had some Iron Man books. But, S.H.I.E.L.D. is a little bit of a weak spot for me."

I'm not secretly on the board of Marvel.

To go from Jon Favreau for Iron Man 1 and 2 to Kenneth Branagh for Thor and the very different world of Thor, it's about how to adapt to Coulson in a different setting and a different world while, at the same time, still have him be a part of the same world.

For me, one of the really cool things about this is that throughout these movies, there have been - and I enjoyed it this way - hints at what S.H.I.E.L.D. is and how they function within this Marvel movie universe which, as you know, is deeply based in the comic books.

I'm just an actor who happened to love these [Marvel] comics when I was a kid, and got to rediscover them.
