Production recently started in Atlanta on the highly-anticipated Captain America: Civil War, the first of Marvel's nine Phase Three movies. While we haven't seen any photos from the set quite yet, El Mayimbe has revealed what is possibly the first official piece of promo artwork, showing Captain America (Chris Evans) and Iron Man (Robert Downey Jr.) lunging at each other in battle. Marvel has yet to confirm if this is official or not, but either way, it still is a striking piece of artwork.

Captain America: Civil War centers on both Captain America and Iron Man, who find themselves divided over the government's new Superhero Registration Act, which forces any individual with super powers to register themselves with the government, to be a part of a global police force. While Tony Stark is for this new law, Steve Rogers is against it, as various heroes find themselves picking a side and joining these two Avengers leaders in battle. The sequel is based on Mark Millar's Civil War comic books, but, of course, we're not quite sure yet how the movie will deviate from the comics, if at all.

Other confirmed cast members are Frank Grillo (Crossbones), Chadwick Boseman (Black Panther), Daniel Brühl (Baron Zemo), Scarlett Johansson (Black Widow), Jeremy Renner (Hawkeye) and Elizabeth Olsen (Scarlet Witch). Anthony Russo and Joe Russo are directing from a screenplay by Christopher Markus and Stephen McFeely, who will all reunite to direct and write the two-part adventure Avengers: Infinity War Part 1 and Avengers: Infinity War Part 2, arriving in 2018 and 2019. Do you think this promo art is real or fan-made? Let us know what you think below, and stay tuned for more on Captain America: Civil War, arriving in theaters almost exactly one year from now, on May 6, 2016.
