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.

It was cool to me, as a fan of the comics, to see some of the villains that end up finding them there, and the way that they abuse Coulson before the superheroes come. I'm always, in the movies or in the animated series, getting into trouble that a superhero has to bail me out of.

I'm not secretly on the board of Marvel.

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.

Agent Coulson takes the work very seriously. He certainly has some fun with Spider-Man and the others, but he takes each of their tasks, including when they get involved with the drama club, way too seriously. The adventures that they come up with are really exciting.

Joss Whedon and all the writers of 'Iron Man' and 'Thor' found a way to keep Coulson saying something that keeps you guessing. I'm really lucky because a lot of people play agents and don't get nearly as much fun stuff to do.
