"Captain America: Civil War" co-directors Joe and Anthony Russo discussed Captain America and Bucky's relationship, how they updated Spider-Man and more in an interview about the final film in the "Captain America" trilogy (via ComicBookMovie.com).

In regards to Captain America's relationship with Bucky, Joe Russo explained, "We've always interpreted the relationship as two brothers. They're very close characters, they have a relationship with each other that is very deep. The bond between them is very strong, [which is] what motivates the storytelling. These are both characters that came from nothing. Captain America was basically an orphan, and Bucky's family took him in. When he was asleep for several years, he lost everything that was dear to him. And when he took the serum and became Captain America, he gave away a large part of himself for a patriotic cause. So, you have a character who is searching for the only thing that he has left from his past... and that's Bucky."

However, the film will tackle more than just Captain America's relationship with Bucky. "I think two of the most endearing scenes in the film are between Steve and Natasha," Joe Russo went on. "And of course, that relationship will carry forward into 'Infinity War.' They have a real respect for each other, but they're very different and they admire the differences in each other, and they find a commonality those differences."

As to Spider-Man's appearance in the film, Anthony Russo weighed in on what made their version of the character different from past incarnations. "It was very important to us that we go younger with the character because what we love about Spider-Man is that he's still a high school student. That's a part of his vulnerability and it's what makes him special in the Marvel Universe; he's very unique. We wanted to play to that aspect of the character. We also wanted to think about 'Who is Spider-Man today?' A lot of times, when you get interpretations of Spider-Man, they're very nostalgic to the origins of the character... We wanted to think about who is Spider-Man today if he's living in Queens, what's the texture of his life like, what's the texture of his relationship with his aunt who lives with him. How can we make the relationship and character very contemporary? That's our goal with the character."

Joe Russo also explained just how they will use "Civil War" to conclude the "Captain America" trilogy. "We're going to go on emotional journeys with these characters. We've got a lot invested in the emotion. We have responsibilities to be mindful of how these people feel about the characters and, at the same time, we also have a responsibility to carry through on the storytelling. As filmmakers, we believe in stakes. You can't have good storytelling without strong stakes. So, there will be a price to pay in 'Civil War.'"

Directed by Joe and Anthony Russo and starring Chris Evans, Robert Downey Jr., Scarlett Johansson, Anthony Mackie, Sebastian Stan and more, "Captain America: Civil War" opens on May 6, 2016.
