'Avengers: Age Of Ultron' Has Worn Joss Whedon Out

Now that he has unleashed his second 'Avengers' movie to global box office domination, Joss Whedon has been able to let his guard down a bit about how exhausting it is to make a movie on this kind of scale. He has hinted that he's done with Marvel for now, and indeed the Russo Brothers have signed on to direct the next two 'Avengers' movies.

Whedon famously said that 'Avengers: Age of Ultron' is "not perfect", and he has gone on to explain the stress involved in the project. "I think I spent too long fighting about this, that and the other in the cut, and the enormous struggles on post-production for a movie like this."

But he's proud of his work on the two films. "I live in these characters," he says. "The things I've done I've been dying to put on screen. Things I never thought they would let you say in a summer blockbuster, I got to say! But these movies are hard; anything in this movie that looks easy, wasn't."

He feels like these two films plot an important trajectory that's echoed in other classic franchises. "The first movie is about putting them together, the second movie is about tearing them apart," Whedon observes. "As an inspiration. The 'Godfather' took an origin story and then in the second film it got very strange and it had this split time frame and it told this very tragic tale of loss of the soul. Even The 'Empire Strikes Back', it's like, 'Wait a minute, things are not awesome!' It is a more grown-up film."

So now he's looking forward to spending time with his children again ("You have to be all-in when you make a film"). And he's leaving the Marvel door open. "You know, I love them and I love that world and my thesps, so it would certainly be hard to walk away completely" he admits. "At the same time, part of me thinks that's the only way I'll get anything else done."
