Just as "Captain America: The Winter Soldier" rattled the Marvel Cinematic Universe putting the events we will see in Joss Whedon's superhero team up sequel "The Avengers: Age of Ultron"--next year's "Captain America: Civil War" will set up the subsequent Avengers: Infinity War - Part I / Avengers: Infinity War - Part II.
The 3rd Cap film will be an adaptation of the Captain America: Civil War storyline that sees Iron Man (Robert Downey Jr.) at odds with Captain America (Chris Evans)
over the Superhero Registration Act - a law that forces anyone with
superhuman abilities to reveal their identities to the U.S. government
and agree to act as a police force for the authorities. Stark supports
the program, Rogers does not because it threatens civil liberties.
As a result Rogers and various others go on the run to avoid arrest.
The life of Cap's girlfriend, Agent 13 (Revenge star Emily VanCamp), is torn apart as her superiors use her divided loyalties against her. Elsewhere, a new villain emerges; the Red Skull begins to make himself known; and The Winter Soldier (Sebastian Stan) again comes face-to-face with Cap....
Badass Digest says that despite the presence of RDJ's in the film Stan's Winter Soldier is still a central figure in the action.
In a new chat with Empire, RDJ. says 'Ultron' will lay the ground work for Stark's turn to the 'dark side':
"It's natural to change your views. The main thing to me
is, what sort of incident could occur, and what sort of framework could
we find Tony in? The clues about where we might find him next are in
Ultron. But what would it take for Tony to completely turn around
everything he's stood for? Joss brings this up all the time. It's kind of weird that
these guys would have all these throw downs all over planet Earth and
yet when the movie's over, nobody minds. What would the American
government do if this were real? Wouldn't it be interesting to see Tony
doing something you wouldn't imagine?"
Downey also said that had he decided not to do 'Civil War,' the film would have been quite
"They said to me, 'If we have you, we can do this, or Cap
3 has to be something else.' It's nice to feel needed. And at this
point it's about helping each other, too. I look at it as a competition
and I go, 'Wow, maybe if these two franchises teamed up and I can take
even a lesser position, with people I like and directors I respect,
maybe we can keep things bumping along.'"
Chadwick Boseman will also be playing Black Panther in the film before getting that solo flick all to himself. Anthony Mackie is poised to reprise the role Harlem crime fighter Falcon.Frank Grillo is set to reprise his role as S.H.I.E.L.D; operative Brock Rumlow, who becomes the villain Crossbones. Samuel L. Jackson's Nick Fury and Scarlett Johansson's Black Widow are also due to return. The casting of Daniel Brühl in a villain role has led to speculation that he has taken over the role of Red Skull.
There's an apparent leak of a casting call sheet from "Cap Civil War" at MovieCastingCall.org that suggests that Bruhl will instead play iconic Marvel villain Baron Zemo in the film.
The adapted script comes from Cap vets Christopher Markus and Stephen McFeely from which Captain America: The Winter Soldier directors Anthony and Joe Russo will call action.
Production on Cap 3 is slated to begin in Atlanta and run from April to August to meet a May 6th 2016 release.
