Anyone who has seen the trailer for 'Captain America: Civil War' would probably think that the film looks like it should be called 'Chasing The Winter Soldier 2' because everyone spends a lot of time running after a troubled Bucky Barnes. Sebastian Stan, who portrays Steve Rogers' former best friend in the 'Captain America' movies, has just confirmed in an interview that Bucky could be trying to run away from his murderous past.

"Where we find him after 'Winter Soldier,' he's in a place where he is learning about himself and he's discovering -- as you saw in the last scene of 'The Winter Soldier,' at the museum -- he's starting to put the pieces together, starting to learn about the past," Stan said. "Where he's been, what he's done and as you'll see in the next movie, it doesn't come without a huge price: emotionally, mentally. Yeah, it's not easy for him learn about what he's done."

What has Bucky Barnes done? For starters, there are rumors that he is responsible for the death of Tony Stark's parents. Although Sebastian Stan didn't address the question about the Winter Soldier's crime, he did confirm that his character will be in a lot of trouble with Iron-Man, sort of.

"Without giving anything away, all I can say is that he's a problem for a lot of people," Stan said.

In addition to that, Sebastian Stan shared how the Winter Soldier felt about Hydra as a whole.

"You have to remember it is the same Hydra, in a sense, that is responsible for him still being alive," he said. "And what happened before the movie 'Winter Soldier' - and there will be a lot of things sort of made more clear in 'Civil War' about what happened with him - kind of set up this relationship that he may always have with Hydra, one way or another. Because in a way they are like his second family, if that makes sense."

'Captain America: Civil War' will hit theaters on May 6, 2016.
