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.

I was an 'Ironman' fan. It was in the '70s. I definitely liked comics and drew a lot of panels on my notebook when I should have been studying - probably why I ended up in the arts.

When I was backstage at Comic-Con, about to go out and do the panel for Thor, and Joss Whedon ran up and introduced himself, I already almost passed out, right then. And then, he said, "I've been meaning to call you. You have a big part in The Avengers. Can we introduce you as part of the cast?" It was pretty Make-A-Wish Foundation. I was pretty sure I was dying and nobody had told me yet.

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.

The technology actually seemed to come at just the right time to make the Hulk - Mark Ruffalo was really able to play both characters.

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.

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.
