If "Captain America: Winter Soldier" was a political thriller, directors Joe and Anthony Russo consider the follow-up film "Captain America: Civil War" as a psychological thriller.
"It's a complicated movie. And yes, it divides these people that you've known to not only be a team, but Cap (Chris Evans) and Natasha (Scarlet Johanssen), in this movie, they're evolving into a surrogate family for each other. So, it's a closer group of people that's being divided. That's a difficult thing to do," they explained during an interview with Collider.
As complicated as it is, however, the directing duo said that there is a good portion of "Civil War" that will undoubtedly make fans laugh "because there are characters in that film, that come from worlds where the tone is more comedic. Not all the characters in that movie have the same history as the Avengers. They're coming at the problem of the film, not embedded with that baggage."
The movie actually has more light moments than dark ones, and they added: "We did have to work very hard at that."
Another thing that the Russo brothers worked hard on is the proper introduction of Marvel's latest (and youngest) superhero - Tom Holland's Spider-Man.
They actually started weaving his story into "Captain America: Civil War" even before Marvel confirmed that he will be a part of the film. They were very worried that Marvel would change its mind about Spidey's introduction but it was already too late to turn things around.
"It was a very long process. Kind of thing we had to lobby for for months. What happens during a long process like that, you're continuing to develop the movie and the character. During the time that it takes you to convince the powers that be to make the jump and let you do that, you've engrained the character so deeply into the story at that point that you'd have to destroy the story to take him out," they shared. "So, by the time we found out that he'd be in the movie, it wasn't so much elation than like 'Thank God! We don't have to blow the whole movie up.'"
The two grew up loving the story of Spider-Man, and they love his contrast to other accomplished superheroes such as Captain America and Iron Man.
"He's a high schooler with this power and responsibility, and it makes him very distinct as a hero. It makes him distinct from the other characters in the Marvel Universe, who are confident, experienced superheroes. It's super important to have that color of the movie, and we felt that it was invaluable and we do think it goes a long way," they explained.
