The first hints of “Captain America: Civil War” will reportedly be seen in “Avengers: Age of Ultron.” Screenwriters Christopher Markus and Stephen McFeely recently revealed that tension will arise between Tony Stark and Steve Rogers in “Avengers: Age of Utron,” and this will set the things in motion for “Captain America: Civil War.”

The duo also said that they have no involvement in the scene in “Avengers: Age of Ultron." “Obviously I’m glad they put that in there, but I don’t even know the relationship between when we decided to [do] Civil War and when that scene was put in, so it could just be good tension, a good scene,” revealed McFeely to Collider.

The scene which will reportedly set events for "Captain America: Civil War" is where Tony Stark (Robert Downey Jr.) and Steve Rogers (Chris Evans) have a disagreement after Ultron destroys Stark Tower. Captain America argues with Iron Man about the latter’s decision to make Ultron. The scene was revealed in the “Avengers: Age of the Ultron” footage released during a Marvel event last year, according to Cinema Blend.

Markus and McFeely also shared their excitement about introducing Black Panther in “Captain America: Civil War”; however, they did not reveal any details about the character. Chadwick Boseman will play the character, and McFeely thinks that the actor is perfect for the role. “I’m very gratified that they went with Chadwick and that he said yes because he’s a good get,” said the screenwriter.

Meanwhile, “Captain America: Civil War” will reportedly be based on the comic book “Civil War.” The plot of the film will be set after the events in “Avengers: Age of Ultron.” The government will pass an act to regulate superhuman activity, which will create differences between the superheroes. Two groups with different ideologies will be formed before an epic battle takes place.

Anthony Russo and Joe Russo are directing the film. It is scheduled to be released in U.K. in April 2016 and in May in the U.S. The filming will begin in two months. The cast of the film includes Chris Evans, Robert Downey Jr. Sebastian Stan, Daniel Brühl, Frank Grillo, Chadwick Boseman, Anthony Mackie and others.
