"Captain America: Civil War" stars Paul Bettany (The Vision) and Chadwick Boseman (Black Panther) have started discussing their characters' nifty wardrobe in the film, and some of the growth they go through in the superhero showdown.

Speaking to Nerdist, Bettany addressed the Vision's classy new clothes, saying, "Vision's trying to find out what it's like to be human...[It's a] light-hearted way to describe that visually...They decided to go with a very English ascot and all of that."

As for Black Panther, Boseman says his decision to join Team Iron Man isn't "really about the idealogical debate in the movie," but rather -- answering without finishing his sentence -- "more about getting to the person who I believe killed..."

Describing his workout routine for the film, Boseman called it, "Very, very strenuous -- hard." He added, "We're still working on it because of the Black Panther movie."

"It's a transformative costume. When you put it on -- the mask, takes you to a place that you feel otherwordly. You feel empowered when you put it on...The armor actually feels like armor," Boseman said of the costume. "I don't even call it a suit, I call it armor."

Paul Bettany and Chadwick Boseman Discuss Humanity and Fighting in CIVIL WAR

Political pressure mounts to install a system of accountability when the actions of the Avengers lead to collateral damage. The new status quo deeply divides members of the team. Captain America (Chris Evans) believes superheroes should remain free to defend humanity without government interference. Iron Man (Robert Downey Jr.) sharply disagrees and supports oversight. As the debate escalates into an all-out feud, Black Widow (Scarlett Johansson) and Hawkeye (Jeremy Renner) must pick a side.

Directed by Joe and Anthony Russo and starring Chris Evans, Robert Downey Jr., Scarlett Johansson, Anthony Mackie, Sebastian Stan and more, "Captain America: Civil War" opens on May 6, 2016.
