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.

When Marvel put together Ultimate Spider-Man and someone came up with the idea of having Principal Coulson, they said, "Do you want to do the voice?" I thought, "I have to do the voice!" Because I have a daughter and we watch some cartoons, I couldn't bear the idea of tuning in and hearing somebody else's voice.

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.

The hardest thing to get right is to figure out how to bring all those characters together, and to fulfill the promise of The Avengers. They really set a very high bar for themselves because you've been setting this coalition up, for these five movies, and they better deliver. And in my opinion, they thoroughly deliver.

When I got the episode where Spider-Man meets Aunt May (voiced by Misty Lee), it was another one of those things where I was like, "I can't believe I have a scene with Aunt May. That's just amazing to me." And they drew her a lot younger and hotter then the Aunt May that I remember.

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.

There's nobody who loves being around actors working more than David Mamet, especially actors bringing his tremendous dialogue to life. I've never seen a movie director who was happier to be directing a movie than Dave.
