Paul Bettany has said that certain characteristics of J.A.R.V.I.S. will remain in The Vision, Paul Bettany he also claims that there will be an "extraordinary" way that the Vision will become allied to [The Avengers](movie:9040).
Comicbook.com quoted the British actor on his role as The Vision in Avengers 2: Age of Ultron, and how he goes from being Tony Stark's artificial intelligence J.A.R.V.I.S.. Bettany was asked if he would miss J.A.R.V.I.S.'s sassy wit he replied,
"I wouldn't say I missed it because I don't think that it entirely went away. You'll see. And as he is born and becomes more realized, it's hard to be ironic when you're -- I know what you're talking about because there's a sort of irony and knowing with J.A.R.V.I.S., but it's hard to be -- I mean, babies aren't particularly ironic. But he's somebody who is learning about the world at quite an exponential rate, and he becomes more sassy as the movie continues."
When asked how the rest of The Avengers were going to feel about having [The Vision](movie:1016359) around he jokingly replied
"Incredibly jealous! It's just been, like I said, a really lovely working experience. I think there's a lot of, initially in the plot, as it were, a lot of distrust, and that has to be navigated by The Vision, and he does it in a quite extraordinarily shocking way. He gains their trust in a real -- it will be -- it's a real roof-raiser of a moment. Everybody will flip."
Maybe something will happen on his and Scarlet Witch's first date!
