While attending a Q&A session, the actor had this to say, when asked if he will get a bigger role in Avengers: Age of Ultron.

"I hope so. Everything in [Age of Ultron] is ramped up though. It kind of blew me away reading [the script]. I don't know how Joss (Whedon) does it, but everyone has gone up another notch and the whole thing is bigger and more exciting and crazier. Yeah, he's a genius."

The actor also revealed that production will take place in London's Shepperton Studios for four months.

"I'm really excited to start Avengers 2 in 2 months and get back on set. Yeah, we're going to meet in London and shoot there for 4 months, so I'm excited to get back together with everyone and catch up."

The Marvel Phase Two sequel has also been confirmed to shoot in Northern Italy and South Korea.
