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.

As a fanboy myself, one of the fun things about the gig has been every time I get a new script, I get to find out more about his day - to-day life and what goes on and what his relationships are.

But what I've also really liked about it is that it not only has Marvel set about... if they just were slavishly trying to bring the comic books to life, literally, I don't the movies would work, because it's different to see something on screen in three dimensions with actors, and they kind of, I believe, are constantly trying to find a way to absolutely respect the source material and at the same time, transform it into something that works and that you believe on screen.

I had worked in this New York theatre company for my first eight or nine years out of college, acting and directing there, and I'd begun to write a little bit.

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 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 think most of the actors that I know that I think are good are kind of funny people. There's just something about being alive to the truth of a moment that makes a good joke that also makes a good actor.
