Marvel Phase Two closes out with a bang this summer as the highly-anticipated Avengers: Age of Ultron and Ant-Man hit theaters worldwide. Phase Three starts next year when Captain America: Civil War hits theaters in summer 2016. Many have assumed that production will begin fairly soon, but today we have a new report from Collider that reveals shooting is actually slated to begin in less than two weeks, on April 1. It isn't known if the April 1 date is for first or second unit scenes, and it's also possible that production could even begin sooner than that date. The site reveals casting notices have gone out, seeking actors from several different ethnicities to be extras in the superhero sequel. In addition, the casting notices have also given us the first official synopsis, which reads as follows.

"Following the events of Age of Ultron, the collective governments of the world pass an act designed to regulate all superhuman activity. This polarizes opinion amongst the Avengers, causing two factions to side with Iron Man or Captain America, which causes an epic battle between former allies."

Of course, the synopsis doesn't come as too much of a surprise. At the Marvel press event where the Captain America: Civil War title was announced, both Chris Evans and Robert Downey Jr. appeared in person, pretending to put up their dukes in a fake showdown on stage. Still, it confirms that this sequel will follow at least the main story from Mark Millar's Civil War comic books. We'll have to wait and see what deviations there may be from the source material.

Anthony Russo and Joe Russo are directing Captain America: Civil War from a script by Christopher Markus and Stephen McFeely. Chris Evans and Robert Downey Jr. will be joined by Frank Grillo as Crossbones, Chadwick Boseman as Black Panther, Anthony Mackie as Falcon, Scarlett Johansson as Black Widow, Jeremy Renner as Hawkeye and Daniel Brühl as a villain, who was recently rumored to be Baron Zemo.
