Most all the actors involved in Marvel Studios productions are understandably tight-lipped -- but after the "Avengers: Age of Ultron" trailer debuted, some of the actors began to loosen up a bit, slowly divulging minor details about Joss Whedon's anticipated sequel.

The Hollywood Reporter spoke with Paul Bettany during the Dubai International Film Festival, and the actor didn't deny speculation that there will be a strong connection between his role as The Vision and his other Marvel Cinematic Universe identity, Tony Stark's J.A.R.V.I.S. AI.

"It's a secret I've kept for about three years, which is really hard, especially with three kids. I'm contractually obliged not to talk about it," he told THR of the character's look. "J.A.R.V.I.S will be there and so will The Vision. But I simply can't tell you any more."

While many assumed that Bettany's Vision would be an extension of the J.A.R.V.I.S. AI, the actor's comments imply that the two appear separately in "Age of Ultron." Bettany previously disclosed that there is a relationship between The Vision and J.A.R.V.I.S., but wasn't able to expand beyond that.

"I can tell you there is one. I'm supposed to keep it vague and mysterious, which I will do," Bettany told CBR in July. "Everything's a double-edged sword, right? I used to turn up for 45 minutes in a darkened studio and be J.A.R.V.I.S. for 45 minutes, and then they'd give me a huge bag of cash, and I would go about my way like a burglar with swag and a striped thing. Like, 'Can this be real?' And now, they want me to work for my money [Laughs], which is great and sweaty and hot. Bearing in mind, which you'll realize once they unveil everything, it's a very sweaty and hot decision that got made, but it's really fucking cool. It's really cool, and it's just been a ball to sort of join this train that is on really clear tracks and really lovely, funny, creative people. It's been a joy, really."
