Heroes square off in the new concept art for Marvel's Captain America Civil WarMarvel Studios

Captain America: Civil War will have a darker take on the iconic superhero, featuring more violence and less humour than its previous movie, Winter Soldier. The movie follows Steve Rogers in his quest to protect his friend Bucky Barnes from the government.

Writer and director duo Joe and Anthony Russo attended the Wizard World Cleveland Comic Con on 27 February and shared some details about the upcoming film Civil War. Joe shared, "We really did a radical reinterpretation of Captain America in Winter Soldier. We were twice as aggressive in tone and execution on Civil War."

The brothers confirmed that Civil War is a continuation of the story started in Winter Soldier and added that Bucky/Winter Soldier (played by Sebastian Stan) will play a more significant role in Civil War. Joe said, "The relationship between him and Captain America will be further fleshed."

Chris Evans in an interview with Disney twenty-three (via Yahoo) said that the Civil War will focus on Cap's struggle with Tony Stark. Evans said, "Even though there are a lot characters, the focus is on Steve and his struggle. Especially his struggle with Tony Stark."

According to the actor, the movie will test Steve Rogers. Evans said, "It's exciting to see a guy who's as optimistic and as selfless as Steve be met with letdown, betrayal, frustration, and selfishness. There are events and people in his life that test him — that challenge him and force him to reevaluate who he is and what he wants out of life."

The movie will divide the Avengers into two camps – one led by Steve Rogers and his desire for the Avengers to remain free to defend humanity without government interference, and the other following Tony Stark's surprising decision to support government oversight and accountability.

As the logo says, "United we stand, divided we fall", it will be interesting to see how the plot plays out in the movie, which is scheduled to hit theatres in the UK on 29 April 2016.
