Lines will be drawn and heroes will be forced to pick sides in the upcoming "Captain America: Civil War." The teams will be split into two, one led by Tony Stark a.k.a. Iron Man (Robert Downey Jr.) and the other by Steve Rogers a.k.a. Captain America (Chris Evans). Hawkeye (Jeremy Renner) and Scarlet Witch (Elizabeth Olsen) are going to side with Rogers in a matchup that could be like a family fight.

In an interview with ScreenRant, Olsen and Renner talked about what it's going to be like in "Captain America: Civil War" for their characters to split sides, as well as how each will approach the fight. Renner wouldn't give exact details about why they divide sides, but he described it as an "it's all fun and games until someone loses an eye" kind of fight amongst friends.

"Two gangs fighting against each other, ultimately knowing that… ya know, it’s like friends fighting friends," Renner explained. "To me it’s fun, personally [laughs], but… no one wants to kill each other."

Both Scarlet Witch and Hawkeye are going to be on the side of Captain America in the new movie, along with the Winter Soldier (Sebastian Stan), Ant-Man (Paul Rudd), and Falcon (Anthony Mackie). Iron Man's team will consist of War Machine (Don Cheadle), Vision (Paul Bettany), Black Widow (Scarlett Johansson) and Black Panther (Chadwick Boseman). Olsen said that despite the fact that she's going up against Tony Stark, it's not because of the bitterness she had towards him in "The Avengers: Age of Ultron." 

"No, I think she by this point has learned that Stark’s not specifically responsible for her parents’ death — that it’s more something that has to do with him stopping — I think there’s even a reference to him stopping his selling of weapons because they cause damage," Olsen dished.

It was also revealed in the interview that Scarlet Witch won't be using her powers of mind control in the film. Hawkeye will also be using nonlethal arrows during the hero vs. hero battle.

"Captain America: Civil War" will find Rogers and Stark at ends with each other over what should be done with The Avengers. People want a system of accountability installed to overlook the team. Rogers believes The Avengers should be able to act on their own with out the interference or control of a government, while Stark believes they do need an entity to direct the team of heroes. 

Co-director Joe Russo told Empire Magazine (via that the movie is expected to set the stage for the next series of Marvel films, including the highly-anticipated "The Avengers: Infinity War." Russo added that the ending will be both "controversial" and "dramatic."
