Paul Bettany has provided his voice as J.A.R.V.I.S., Tony Stark's indelible A.I., in four movies, including Iron Man, Iron Man 2, Iron Man 3 and Marvel's The Avengers. But in Avengers: Age of Ultron, he will finally appear in the flesh as Vision, and it was the first time he actually got to interact with the ensemble cast on set. Speaking with Radio Times, the actor was able to provide a bird's eye view into the production, and he was beyond impressed with what he saw. He even claims that its the most ambitious project Marvel has attempted yet:

"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...This is the biggest thing Marvel have ever done. It was enormous."

While Paul Bettany hasn't seen the finished film yet, he did get to see the first footage along with everyone else at this past year's Comic-Con. About that experience he says:

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 was the same. Including Samuel Jackson - and his whole modus operandi is 'I've seen everything before, I'm the most chilled out, relaxed man and I've seen everything...'and he was as knocked out as anyone. It's huge."

Are you as excited for Avengers: Age of Ultron as Paul Bettany seems to be? We only have four and a half months left to wait. Will we see Vision in action before then? Or are they saving our first glimpse at Vision in the flesh for price of that admission ticket? We'll have to wait and see!
