Just from the title alone, fans can tell that Captain America: Civil War will feature some explosive action, literally and figuratively, with Marvel's greatest heroes divided and fighting against each other. This epic adventure will set the stage for Phase Three, which culminates with Avengers: Infinity War Part I and Avengers: Infinity War - Part II, and are set to shoot back-to-back at the end of this year. It may surprise some fans to hear director Joe Russo discuss the "love story" that lies at the heart of Captain America: Civil War, between none other than Steve Rogers (Chris Evans) and his longtime friend Bucky Barnes, a.k.a. The Winter Soldier (Sebastian Stan). Here's what the director had to say about this intriguing dynamic.

"What's fascinating about the Cap-Bucky story as well is it's a love story. These are two guys who grew up together, and so they have that same emotional connection to each other as brothers would, and even more so because Bucky was all Steve had growing up. Is he good or is he bad? Steve has to answer that question for himself, and there are other characters in the movie who hold the opposite point of view. It becomes a very explosive. It incites a lot of conflict."

We first met Bucky Barnes in Captain America: The First Avenger, where we learned that Bucky was childhood friends with Steve Rogers, long before he became Captain America. While he was thought to have died in that movie, he came back to life as The Winter Soldier in Captain America: The Winter Soldier. We last saw Bucky in the end credits sequence of Ant-Man, where he was found by Cap and The Falcon (Anthony Mackie), and he was starting to regain his memories. Empire also spoke with Sebastian Stan, who offered his take on the Bucky-Cap relationship.

"I think it's easy and generalizing it to say that they're lovers, when you're forgetting that one has a lot of guilt because he swore to be the protector of the other, the father figure or older brother so to speak, and then left him behind. I have no qualms with it but I think people like to see it much more as a love story than it actually is. It's brotherhood to me."

Bucky will be fighting alongside his old friend in Team Cap with The Falcon (Anthony Mackie), Agent 13 (Emily VanCamp) and Ant-Man (Paul Rudd). Team Iron Man includes Tony Stark (Robert Downey Jr.), Black Widow (Scarlett Johansson), Vision (Paul Bettany), War Machine (Don Cheadle) and the new character T'challa (Chadwick Boseman). It was also revealed in the new trailer for Captain America: Civil War that the new Spider-Man (Tom Holland) will be on Team Iron Man, but it still isn't known how large his role is. What do you think about the Cap and Bucky "love story" in Captain America: Civil War?
