Captain America Civil War featurette reveals Steve Rogers and Bucky Barnes' emotional bonding

A new featurette of Marvel's Captain America: Civil War reveals the real reason behind the epic war between the Avengers. As of now fans know that the impending war between Chris Evan's character and the Iron Man is going to divide the superheroes within the Marvel Cinematic Universe (MCU) but what ignites the war is the centre of the movie's plot.

The movie is set to explore the back story of Steve Rogers, the first Avenger of MCU, and his deep emotional connection with Bucky Barnes aka the Winter Soldier. Evans and executive producer Nate Moore have divulged more details about Bucky's rogue nature and Steve's devotional friendship that will ultimately result in a great disaster.

"I don't think Steve was the kind of guy who grew up as Mr popular. Bucky was the guy who has always been there, who has always had his back. Winter Soldier is his best friend, his only friend in the world. There is an undercurrent plot going on with the Winter Soldier, which sets the maturity of the avengers on its tail," Evans explains in the featurette.

Moore hints that Steve's blind love for his old friend will be the biggest cause of rift among the Avengers. "Caps' allegiance more than anything is to Bucky Barnes, his best friend. And that's the thing that, when we put in the middle of the Avengers, will cause Caps to think twice about keeping the team together."

Captain America: Civil War will premiere in theatres on 6 May 2016, in the US.
