I was a football player at college and dislocated my thumb. I was out for a bit and passed the theatre and saw some lovely drama students walking into an audition for 'Much Ado About Nothing' and thought: 'That's what I'll do when I recover.' I joined that production and was hooked.

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.

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.

Speaking as Coulson, it's unclear. I feel like that are other formidable S.H.I.E.L.D. elements and they don't have Coulson's connection to some of these people. I think what I like about what seems to be going on is there are differing opinions about who's where on the hierarchy and I think that's some of what goes on in the movie.

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.

You know I grew up on the Batman movies, and they had some terrific actors in, but you know a lot of the other ones - it wasn't always the case that you had people the caliber of Jeff Bridges or Robert Downey, so to kind of show up and work with Jeremy Renner or Robert or with Mark Ruffalo, any of them, Chris Evans, Chris Hemsworth, the caliber of people you're acting with, to me, is really fun. From the first day I started doing scenes with Robert, it's been one of the funnest experiences I've ever had.

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.
