With the news coming last week that the next Captain America movie would set up a fight between the titled hero and Iron Man, many fans were wondering what would instigate a fight between the two superheroes and a Marvel executive clears up what the movie will mean.

One Character Might Stop The Fighting Between Captain America & Iron Man

In an interview with ABC News last week, Marvel Executive Editor and Senior VP Tom Brevoort talked about the Civil War plot, where it came from, and what it means for the Marvel universe moving forward.

"Civil War was a project we did in 2005. It made headlines at the time. It was very much taken form the zeitgeist of the era," he said.

"In the post 9-11 world, one of the questions that we as a nation had to grapple with is the question of the balancing act of the need for security and the desire for privacy and public freedom. That was dramatized in Civil War."

He also spoke about what would make Captain America and Iron Man fight in a plot that will probably tear fans apart who love both characters.

"From the point of view of Captain America, this was an infringement on the civil liberties of these people, this was overstepping turning all these super-powered individuals and turning them effectively into soldiers. Iron Man on the other hand, saw the validity of this," Brevoort said.

"Just because a guy has powers and puts on a costume doesn't mean he is trained to use them responsibility, even if his intentions are good, people can get hurt. This became an ideological divide between Cap and Iron Man and it played out in bold superhero fashion with laser blasts and fisticuffs. Different characters within the Marvel aligned themselves philosophically with one side or the other."

Captain America: Civil War is set to open in theaters on May 6, 2016.
