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.

It's a little strange, after all these years of working on camera, but once you start to watch the other people who do this a lot and realize how much of what you're doing has to just come through your voice, I found it really interesting.

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.

I'm just an actor who happened to love these [Marvel] comics when I was a kid, and got to rediscover them.

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.

The great thing about Coulson is that he's a little bit like a party game, where the next person who gets ahold of him gets to write another sentence. I'm constantly learning more and more about the guy.

I've never seen a movie director who was happier to be directing a movie than Dave [Mamet]. His sets, everyone who's ever been involved with one of them will tell you of the funnest, funniest sets you can be on.
