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.

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.

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.

All the PG-13 superhero movies are depriving me of the gore that I need.

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.

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.

I think about it, and I realize there's been some version of a Batman or Spiderman or Superman franchise since I was a boy, since before I was a boy.
