You can never discount the pleasure of showing up to work with Scarlett Johansson and now Cobie Smulders. That's just a day that's easy on your eyes.

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.

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.

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.

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.

I'm not in Captain America because it takes place in the '40s. Both he and Bruce Banner are relationships that evolve during this - two more rock stars that I got to get on stage, ready to play ball.

I'd be just another Marvel fan, only with a little bit bigger smile, when I would get the script and be like, "Oh, my gosh, Agent Coulson knows that?
