Fans are all in hot anticipation for 'Captain America: Civil War,' the movie where we witness longtime Avengers oppose each other for what they believe is good for the world.

The forerunners in this movie, Chris Evans as Captain America, and Robert Downey Jr. as Iron Man, were available to speak with IGN on their characters and what roles they will play in the film.

Downey begins with speaking on the difference between the two:

"On the surface it's that. But also [Tony] Stark grew up under the shadow of this very close father son/relationship that Howard [Stark] had with Steve [Rogers, Captain America] so I'm sure that it's driven by some unconscious motives. At the same time, they're two vastly different generations of moral psychology. And arguably, Cap's is more righteous. But I think Tony is a realist. So that's always a fun dynamic to play."

Evans expresses his excitement to explore the dynamic in their relationship as well:

"This is why I think the next movie is going to be so effective - Civil War - because there's a flip-flop in the way we approach things. Tony's always been a trailblazer. He's always been his own man and he bucks authority. He dances to the beat of his own drum. Cap comes from a world or order, and organization, and hierarchy, and structure. And I think after Cap 2 when SHIELD kind of fell that Cap kind of realized that you can't necessarily trust the people around you - or you can't trust the system. I think he now is kind of starting to follow his own heart, and do his own thing, and as a result there becomes this kind of flip-flop in perspective."

'Captain America: Civil War' premieres in theaters on May 6^th, 2016.
