'Captain America: Civil War': Cast, Plot Revealed

— -- "Captain America: Civil War" began filming in Atlanta today and Marvel revealed plot points and a cast list for the May 2016 Marvel blockbuster. It's impressive, to say the least.

Here's your cast:

According to Marvel.com, "'Captain America: Civil War' picks up where “Avengers: Age of Ultron” left off, as Steve Rogers leads the new team of Avengers in their continued efforts to safeguard humanity. After another international incident involving the Avengers results in collateral damage, political pressure mounts to install a system of accountability and a governing body to determine when to enlist the services of the team. The new status quo fractures the Avengers while they try to protect the world from a new and nefarious villain."

Last year, ABC News spoke to Marvel VP Tom Brevoort to talk about how Civil War went down in the comics, not the upcoming films.

"Civil War was a project we did in 2005 ... It was very much taken form the zeitgeist of the era. 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," he said. "The inciting incident is a conflict between a young team of teenage superheros and super villains. They engage in a battle ... one of the villains is this character Nitro, who explodes and he blows up, taking out a school and killing like 700 people, most of them kids ... this set up a scenario in which there was a movement and a desire for superheros to register with the government or register with SHIELD. Come forward and get their credentials and be trained."

Brevoort added that Captain America faces off against Iron Man in the film -- former allies, now disagreeing on a fundamental issue.

"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. 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," he said.
