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.

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.

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.

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.

As you can imagine when you have to summon a force like that together, the opposing elements are pretty freaking gnarly. I would think of those pioneer movies where they've got the cook and the ladies loading the guns and firing at the surrounded wagons. I don't put Coulson in that category, I think he is on the upper tier of people who come to scrap at situations like that but everybody's involved.

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.
