It may be called Captain America: Civil War, but there are a ton of heroes in the movie.
Chris Evans' Steve Rogers is joined by Iron Man (Robert Downey Jr.), Falcon (Anthony Mackie) and Black Widow (Scarlett Johansson), as well as new avengers Scarlet Witch (Elizabeth Olsen) and Ant-Man (Paul Rudd). And that's still only scratching the surface of the number of super people assembling for the new Marvel movie.
"I will take all the help I can get," Evans told ET with a laugh when we visited the Atlanta set of the film. "Bring them all back!"

Especially since everyone won't be getting along this time. "Something happens where Tony Stark and I have opposing views, and it results in a little bit of conflict," Evans teased.
There was plenty of conflict behind the scenes, too -- or some light hazing, at least.
"We bully them," Mackie joked of initiating new costars -- like Olsen, who joined the Marvel Cinematic Universe in last year's Avengers: Age of Ultron. Evans chimed in, "Yeah, swirlies, nuggies, Indian rug burns."
"I feel like, little Olsen, we bullied her a lot," Mackie added.
Still, Olsen said she felt less like the new kid this go-around. "I feel far more comfortable this time," she revealed. "It's nice to be a part of the team, as opposed to being this outsider thing."

Civil War might just be bigger and better than any Marvel movie yet -- at least, if the stunts and action we saw on set were any indication. Watch the video above for an exclusive look, including an epic fight scene between Cap and Bucky (Sebastian Stan).
Apparently everything isn't cleared up between those two, after all.
Off screen, there was a different kind of battle brewing among the Avengers, in particular between Evans and Mackie, who couldn't help but brag about his dancing skills.
"I can break an ankle, kids," the always-charming Mackie claimed.
"Did you say that? I have challenged you to a dance-off many times and there's always a story, there's always a reason," Evans rebutted.
"Don't be the Pacquiao to my Mayweather," Mackie warned. "You don't want that. You don't want that drama."
"Dance-off challenge!" Evans declared. And now we have the plot for Captain America 4.
Captain America: Civil War hits theaters on May 6.
Meanwhile, Sebastian Stan -- aka. the Winter Soldier himself -- told ET that the latest Captain America installment is going to be "heartbreaking." Check it out in the video below.
