Captain America 3: The Vision actor Paul Bettany on Civil War storyline and what makes Marvel films click

Actor Paul Bettany has had a pretty dynamic story arc in the Marvel Cinematic Universe. From being Tony Stark's U.I. system and sidekick of sorts - J.A.R.V.I.S - to transforming into The Vision who takes down deadly foe, Ultron.

Now, Bettany is all set to reprise his role in the upcoming Captain America: Civil War where his character, The Vision, will side with Iron Man in the war between superheroes. The actor recently spoke about the upcoming Marvel epic comparing the storyline to real-world issues.

"I think it's really interesting, the way that a huge, epic superhero extravaganza is discussing a really interesting question, which is about people unilaterally going into other people's countries and their intervention there," Bettany stated in an interview with Collider. "It's actually an interesting thing to talk about in a massive forum like that."

The actor also explained that the reason why Marvel films are as big and popular as they are, is because they are made by fans who know what it is about the stories and the characters that connects with the audience.

"I think fans feel that they're in safe hands, and the reason they feel like they're in safe hands is because the films are being made by fans and they remember what it is about these stories that connected with them, in the first place. That's why they have heart."

Captain America: Civil War opens in theatres on 6 May 2016.
