Here are Joss Whedon's eight most revealing quotes.
1. The sequel is much bigger
"The cast is bigger," says Whedon. "The scope is bigger. We have more to work with. We have a bigger world to work with and a bigger world for [the Avengers] just to be in. Once they exist as a team, we have to deal with what everybody thinks about that, and what that means to the world. So it's not as simple as it was."
2. Avengers: Age of Ultron existed before The Avengers came to be
Here, Whedon jokes that he came up with the Avengers sequel before he even began work on the first one.
4. Everyone is strong, but damaged with power
"'Strong but damaged by power' describes every person in this movie," explains Whedon. "It may, in fact, describe what the movie is about. You know, the more power that we have, the less human we are."
With Quicksilver, did the X-Men Quicksilver that just came out change your visual approach to anything? The speedshots?
WHEDON: Not really. I mean, there’s some things that we now would probably care to avoid just so that we’re not… But we were never doing the same version. Obviously, at some point we’ll go into slow-mo because that’s what’s fun about a super-speedy guy. For me, what’s fun about Quicksilver isn’t necessarily seeing Quicksilver, it’s seeing the Avengers the way he does. They really took to the mattresses with that one scene, but he’s just a very different guy in ours and I think we’re just kind of proceeding as planned.
