I had worked in this New York theatre company for my first eight or nine years out of college, acting and directing there, and I'd begun to write a little bit.

I'd be just another Marvel fan, only with a little bit bigger smile, when I would get the script and be like, "Oh, my gosh, Agent Coulson knows that?

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."

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.

The world of Ultimate Spider-Man is funny. I can't imagine a live-action film where he's Principal Coulson and dealing with some of the pranks from these guys.

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

The technology actually seemed to come at just the right time to make the Hulk - Mark Ruffalo was really able to play both characters.
