Iron Man
Iron Man will play a villain of sorts in Captain America 3 Marvel official website

Captain America: Civil War will feature almost all the characters from the Marvel Cinematic Universe in an epic battle against each other. The root of it is the feud between Cap and Iron Man over the Superhero Registration Act that the government intends to implement.

Being a Captain America film, several fans initially wondered if Tony Stark/Iron Man will end up playing the movie's primary villain (of sorts). Well, actor Robert Downey Jr sheds some light on that.

Talking to Entertainment Weekly, RDJ discussed how Iron Man isn't necessarily the "bad guy," but he's definitely the antagonist. "It didn't bother me at all," said The Avengers star. "I've always thought of it in some ways that Tony is the antagonist to himself in his own story, so this isn't a problem. This guy understands problems 'cause he is a problem. And he tends to create problems."

If you think it's uncharacteristic of Tony Stark to call himself a problem, Downey Jr adds that he doesn't think Stark is wrong. "I'm not having to patter around what I think the worldview is. I wholeheartedly agree with what he does in this [film].... Which is, by the way, more than I could say for some of the other movies."

"Following the events of Age of Ultron, the collective governments of the world pass an act designed to regulate all superhuman activity. This polarizes opinion amongst the Avengers, causing two factions to side with Iron Man or Captain America, which causes an epic battle between former allies," reads the film's official synopsis.

Captain America: Civil War is slated to release on 6 May 2016.
