Actor teases plot details and discusses his own future in the franchise

Robert Downey Jr has discussed the eagerly-anticipated sequel to The Avengers and his own future as Iron Man in the franchise.

The actor, who has played wisecracking scientist Tony Stark in several Marvel pictures since 2008, is set to reprise his role for The Avengers: Age Of Ultron. Speaking to Variety about the film, Downey Jr hinted that Jeremy Renner’s character Hawkeye would play a pivotal role.

“My two-year-old is crazy about Hawkeye, and I think Jeremy has a lot to do with the plot,” he said. “There are always so many plates to spin to get these things half-right, and I’m really excited about this one.”

He also discussed his own future in the series and admitted that he would not always be the best fit to play the character in the future, adding: “The smart money is you have to look at everybody’s age. I’ll put myself at the top of the list. Sooner or later, they’ve got to start over and get somebody young. I’m not there with them yet.”

Since its release in May 2012, The Avengers – a superhero ensemble movie uniting Iron Man, Thor, Captain America and the Hulk – has become the third highest-grossing film of all time, taking over $1.5 billion (£930 million) at the box office worldwide.
