Marvel will blow you away with Avengers: Age of Ultron – at least according to new star Paul Bettany!

Less than four months remain until Avengers: Age of Ultron hits cinemas on May 1, 2015.

Paul Bettany, who voices Tony Stark’s J.A.R.V.I.S. and debuts as new Avengers team member The Vision (an android), has spoken to Radio Times about Joss Whedon’s ambitious superhero movie.

Bettany admits to being blown away by the experience, saying, “I’ve never been on a bigger set on my entire life than in The Avengers [Age of Ultron]. One [part] seemed to be the corner of a town, with helicopter cameras, and drone cameras flying about. I just haven’t seen anything that big, so it was like being a kid on a film set again.”

The English actor goes on to declare Age of Ultron, “the biggest thing Marvel have ever done.”

“It was enormous,” he gushes. “I remember, we were at Comic-Con, and they showed a portion of the footage, and I was just gobsmacked. And I looked down the row and every one of the Avengers [actors] was the same.”

In related news, Captain America actor Anthony Mackie (the Falcon) still has hopes about being included in Age of Ultron, despite not appearing in the original script.

He tells Comic Book Resources, “At this point, I have not [shot anything for Age of Ultron], [but] I hope, I hope, I hope, I hope. They’re doing reshoots and that’s why I’m letting them know I’m available. So whatever weekend they want me there, I’ll fly myself out and shoot whatever scene they want me in.”
