It's the interaction between those characters that really makes that movie as special as it is, and I'm proud to say, as you probably know, it was the highest grossing film of 2012, it's the highest grossing film that Walt Disney has ever put out, and it's the third highest grossing film ever, in the world.

We knew that, in doing something that's based around the world of the movie and how popular that is, we really wanted to do the biggest show that we've ever done, in terms of the look of the show.

We want to be able to let the audience get to know these folks. One of the things about The Avengers, over the last 50 years, is the fun of changing up the gang and bringing in new characters.

The Marvel cinematic universe and the Marvel animation universe are things that are very true, in terms of the DNA of what it is. But if, at the end of the day, all we're doing is telling stories that have appeared in the comic books already, then we're not really challenging anybody.

When we first sat down and talked about how much of the show we were going to do based on the movie, there are certainly things you can see right away, but we wanted to make sure that the audience who maybe never saw the movie or has maybe never seen any of the Marvel characters before - and I know there's three of them left on the planet - could have someone that could be their eyes and take them in.

It really showed that you can do a major motion picture, from the folks at Marvel, that has multiple characters on an epic scale. On top of that, it also showed us that one of the most important elements is a certain kind of levity.

This is, in fact, the biggest show that Marvel television has ever taken on, in the animation world. We had a real challenge that was posed to us, and that was this little, tiny art-house movie that came out last year, that I don't know if you saw, called Marvel's The Avengers, written and directed by our friend Joss Whedon, and it really set the template.
