Joss Whedon: 'Avengers' Sequel Was a "Nightmare" Due to Expanded Superhero Cast

Joss Whedon on the differences between The Avengers and Much Ado About Nothing

"They’re pretty easy to separate. There wasn’t a moment where I was like, 'Oh, we gotta get the Hulk stuff for the wedding scene.' They were breathing space from each other. The pressure, obviously, of The Avengers was a particular thing but at the same time, I had dozens of people working for me. Much Ado was a much more freeing experience, but at the same time it was just me and Danny on our laptops editing it, so I didn’t have anybody to blame. It was great. One would fulfill me in one way, and one in the other. Instead of being more exhausting, it was less."

"I haven't worked this hard since I had three shows on the air," says the director, calling the Marvel film his "hardest juggling act."

Directing arguably the most anticipated sequel of the year is no easy feat. But Joss Whedon said dealing with fans' expectations for Avengers: Age of Ultron was not the main challenge — that honor was reserved for the expanded superhero ensemble.

"Shoot me in the face! It is a nightmare. I long for the simple movies like Serenity!" he told U.K. magazine SFX. "This is the hardest juggling act I have ever, ever tried to pull off."

With the Avengers' ranks having swelled to include Elizabeth Olsen’s Scarlet Witch and Aaron Taylor-Johnson’s lightning-fast Quicksilver, together with an expanded nonvoice role for Paul Bettany's android, the Vision, Whedon has had to ensure everyone fit in the same universe without looking out of place.

"They’re very disparate characters. The joy of the Avengers is they really don’t belong in the same room. It’s not like the X-Men, who are all tortured by the same thing and have similar costumes," he explained. "These guys are just all over the place. And so it’s tough. Honestly, this is as tough as anything I’ve ever done, and I haven’t worked this hard since I had three shows on the air."

One of the standout characters from the first outing was the Hulk, and Whedon admits that there’s going to be more of Mark Ruffalo’s massive green rage-machine in the follow-up.

"There is more Hulk in this movie than there was in the last film. But what I’m excited about is we shot this movie very differently. I was running a lot of cameras, I was shooting long lenses, which I don’t usually do," he said, adding that he aimed to shoot the film a little like a documentary.

"What I love is we have the opportunity, because we went in with this mission statement, to shoot the Hulk like a character in a movie, and not like a ‘Look what we’ve got!’ We have ‘overs’ – blurry ‘Hulk’s over there!' bits, very quick shots. Everything isn’t, ‘We built the Hulk so for God’s sake you’re going to watch him in this long take, full-frame, the whole time!’ We really got to make him one of the characters in the movie. And that was a gift."

Avengers: Age of Ultron releases in the U.S. May 1, a week after it opens in the U.K. and other parts of Europe.
