Captain America: Civil War fan-art

Captain America 3 stars Chris Evans (Captain America) and Anthony Mackie (The Falcon) have compared the superhero feud in the upcoming Civil War movie to sibling rivalry and disagreements in a family.

"...It's more of a family dispute," said Mackie while talking about the movie at Marvel's D23 Expo on 15 August. "That's what's so great about this movie and the characters and how they work together. It's more so when you have a sibling rivalry. The reason people can relate to these characters so much is because they can relate to what they're going through; everybody's fought with one of their siblings or one of their friends, wanted to make up with them, but couldn't figure out the best way to do it and that's kind of how Civil War works."

Adding to the entire "brothers-at-war" take on the Marvel film, Evans stated that the story plays upon the "family dynamic of people that you may not get along with, but you cannot just cut them out of your life - that's what makes the stakes so high".

Fans can expect the supporting characters in the Marvel Cinematic Universe to play a significant role in the Iron Man vs Captain America epic. Evans praised the fact that Captain America 3 makes time for continuing the stories of the supporting characters and their relationship with Steve Rogers.

"Marvel has a lot of balls in the air, you've got a lot of movies that they're trying to bring together. The truth is, there's a lot of things they're trying to marry, and when you have characters like Falcon and Winter Soldier, these movies are really effective in progressing those storylines., even in just this movie alone, the relationship with Cap and Falcon and Winter Soldier," he explained.
