Robert Downey Jr says Civil War plot will be set up in Avengers 2, talks about Iron Man's negative role in Captain America 3

Robert Downey Jr in an interview revealed some details about his upcoming blockbuster Avengers: Age of Ultron, and Iron Man's villainous role in Captain America: Civil War.

Downey Jr told Empire Magazine, that he would not call Tony Stark the villain in Civil War, as it is not an Iron Man Film, and noted, "It's natural to change your views."

The actor also revealed that Civil War will be set up in Age of Ultron itself.

He added, "The main thing to me is, and this is where I think the Russos are quite brilliant and where Kevin backed the play, is what sort of incident could occur and what sort of framework could we find Tony in? The clues are in Ultron about where we might find him next."

The third Captain America movie will be an adaptation of the Marvel's Civil War Comics storyline that saw Steve Rogers and Tony Stark take on each other, over the superhero registration act.

The actor explained that Civil War and Tony Stark agree to the government's plan of forcing superheroes to register their real identities.

He said, "When the first Iron Man came out the liberals and conservatives were both like, 'You're our guy'. Yes! Score! But the idea of Tony being able to march into Washington and say, 'I'll sign up', wouldn't have made sense if the political climate in the real world hadn't shifted the way it has."

Downey Jr continued, "It's a little bit of things following a real world continuum in, 'What would you do?' There's always the bigger overarching question, that Joss brings up all the time - it's kind of weird that these guys would have all these throw downs all over planet Earth and it looked like a little collateral damage happened over there, and yet when the movie's over, it's like nobody minds. You have to figure, 'Were you to ask the question, what would the American government do if this were real? Wouldn't it be interesting to see Tony doing something you wouldn't imagine?'

When the actor was asked by the website whether he saw Tony Stark as a villain in the movie, he replied, "Ultimately it's Steve's story; it doesn't say 'Iron Man 4: Civil War'. I think that's great too. I think Chris [Evans] has been hungry to bring even more of an underside and some shadow to that."

He added, "I remember the comics - on the surface you got the sense that Cap was baseball and apple pie, but underneath there was all this churning stuff of being a man out of time. Now we know he's made his peace with that. What's the bigger issue? It can have a little something to do with the past, but it can be about someone becoming more modernised in their own conflict."

Avengers: Age of Ultron will release in theatres on 1 May 2015.
