This May, the Avengers will find themselves at odds with each other in "Captain America: Civil War." Over a series of interviews, cast and crew members like Joe and Anthony Russo, Chris Evans, Robert Downey Jr., Chadwick Boseman and more weighed in on the personal nature of the film's conflict and hinted at what sets them against each other.
"I almost feel like sometimes [Tony Stark] is some (old man) who goes back to the neighborhood and goes, 'Kids, it doesn't have to be like this,'" Downey told USA Today.
"Regardless of whose argument is what, communication is about really being able to fully see the other person's point of view," he added. "I fully see Cap's point of view -- I don't know if Tony does."
Regarding Black Panther, Boseman said, "He's definitely his own guy... There's no 'I'm going to do whatever you say because you're the leader of this team.' That's not who he is. But I would say that's also true of other characters."
As to why "Civil War's" main conflict will be Cap's most difficult challenge yet, Evans told USA Today, "It's boring when a good guy knows how to be a good guy... It's much more dynamic when a good guy isn't sure what the good guy move is and has to debate another point of view from someone who may be very close to him."
"Nobody's wrong here," he added. "No one's promoting evil. No one's the bad guy. We just have different ways of being the good guy and that can get fiery."
Sebastian Stan also brought up Bucky's struggle, explaining, "Cap is his only shot at survival... It's not like everyone's high-fiving before going to war. There are still tensions."
Additionally, directors Joe and Anthony Russo called the film "a psychological thriller" during an interview with Collider.
"We dug deep to find motivations that were extremely personal and very emotional to the characters," Joe Russo explained. "It's not for all characters because like any fight people take sides and some people have stronger motivations than others, and as the fight gets worse people drop out because they don't have the stomach for it. We have a couple characters that go to the end and they go to the end pretty hard and pretty ugly."
"Tony has the most emotional motivation in the film. The most human motivation. Cap's is philosophical," he added.
Evans went on to discuss how Cap truly goes rogue, as he cannot "lean on the structure of society... So it's the first time he really doesn't know what the right answer is."
Joe and Anthony Russo also explained what separates Boseman's Black Panther from the rest of the cast, saying he has "a movement style that he brought because he has a background in martial arts and it's fascinating. He moves like none of the other characters in the universe."
"[Black Panther] is a warrior, and it's part of their tradition," shared scriptwriters Christopher Markus and Stephen McFeely. "It's not like he's like, 'Who is that masked guy that's doing this stuff?' Everybody knows it's him, and they expect that it's him, and they pray to God, or even praying to him in some cases, that he would do the things that he's doing. Which is much different than most of the superheroes in which you don't know their identity and you don't know when they might show up. There's an expectation that's much different."
Boseman added that Black Panther is "a tactician. He's a strategist, so he appreciates that thought process. So it's both sides."
As to why the Avengers are so evenly matched despite their differing power levels, producer Nate Moore explained, "I think it prevents Tony Stark from blasting Hawkeye in the face with repulsors... You're just not gonna do that. That doesn't mean you still can't have a battle that has real stakes and tension but it does mean for characters like Vision, especially, who feels like he is the protector of humanity in some respects, from going full Vision power because are you gonna do that to somebody like Black Widow? Are you gonna do that to Wanda?"
