I felt like people really do their best work when they're having a really good time and feel safe to push the envelope and make a jackass out of themselves.

As a fanboy myself, one of the fun things about the gig has been every time I get a new script, I get to find out more about his day - to-day life and what goes on and what his relationships are.

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.

But what I've also really liked about it is that it not only has Marvel set about... if they just were slavishly trying to bring the comic books to life, literally, I don't the movies would work, because it's different to see something on screen in three dimensions with actors, and they kind of, I believe, are constantly trying to find a way to absolutely respect the source material and at the same time, transform it into something that works and that you believe on screen.

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.

What I think is incredible about what Marvel has done and with Jon Favreau I think really maybe helped come up with, is what the template is.

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."
