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.

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.

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.

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.

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.

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 guess what we know about the Avengers is there's a reason why all of the heroes that we've been meeting, from Thor to Captain America - everybody - they need to work together.
