Just judging by the title, we know that 2016's "Captain America: Civil War" will feature all of Marvel's good guys aligning themselves with opposing ideologies spearheaded by Captain America and Iron Man. While we know that a lot of characters have been confirmed for the film, quite possibly more superheroes than have ever appeared in one Marvel Studios film before, we haven't yet learned which heroes will align with Cap and which will side with Iron Man.
Heroic Hollywood, citing an unnamed source close to the production, claims to know the lineups of each Avenger's "Civil War" team, and -- if it is true -- it has some big surprises on it. While this is still firmly a rumor and not official, we're still putting up spoiler alerts for those that don't even want to see conjecture about the film's plot.
According to HH's source, Captain America will be fighting alongside Hawkeye, Falcon, Scarlet Witch, Ant-Man and the Winter Soldier. Iron Man, meanwhile, will count the Vision, Spider-Man, Black Widow and War Machine on his side. Black Panther is absent from both lists as it's already been made clear by Marvel Studios president Kevin Feige that he will play a neutral role in "Civil War."
Some of this information lines up with what has already been revealed. From the post-credits scene in "Ant-Man," we already know that Falcon and Ant-Man are on Cap's side and that they have Winter Soldier in custody. Jeremy Renner was spotted just a few weeks ago wearing a "Team Captain America" hat, which looks like may have actually been accurate.
Iron Man's team is more surprising. Vision, Black Widow and War Machine were all part of Cap's new Avengers squad at the end of "Avengers: Age of Ultron," so this implies that they've all turned against him. Black Widow's inclusion on the team is even more surprising considering how closely she worked with Steve Rogers in "Captain America: The Winter Soldier."
Most likely we'll learn more about the sides as official trailers and footage start making their way online towards the end of this year and in early 2016. "Captain America: Civil War" opens on May 6, 2016.
