A new preview for Captain America: Civil War gives Marvel fans more insight into the dark, game-changing plot.
The preview, featuring actor Chris Evans and directors Joe and Anthony Russo, is part of a featurette included in the box set collection of Marvel Studios Phase Two films.
"It's going to challenge the way you think about Tony Stark. It's going to challenge the way you think about Steve Rogers, and when you come out of that film, nothing will be the same," director Anthony Russo said in the video.
The preview includes previously unseen footage of the upcoming film including commentary from actor Robert Downey Jnr on a fight scene between allies turned enemies Captain America and Iron Man.
"There's this rift and we put their relationship in the balance, as well as The Avengers," says Downey Jnr.
Marvel Studio president Kevin Feige and actor Chadwick Boseman also discuss the role Black Panther, played by Boseman, will have in the film.
"We wanted to have a third party that wasn't even necessarily involved in that argument and we kept talking about Black Panther," Fiege says.
"He's a monarch and at the same time he's a superhero but there's a certain mystery about the character," Boseman said.
The film premieres May 2016 and will be the first from Phase Three of Marvel Studio's Cinematic Universe.
