During a press event in Beijing today, "Captain America: Civil War" directors Joe and Anthony Russo confirmed a few more cast members for the 2016 Marvel film.

"We've been preparing for the movie since the one debuted last year," said Anthony Russo. "So, we've been working on it for a long time now. We're very happy how it's coming along. 'Captain America 3' is going to be called 'Captain America: Civil War' and it's going to star Chris Evans as Captain America, Scarlett Johansson will be back, Winter Soldier [Sebastian Stan] will be back, and Robert Downey Jr. as Iron Man will also be joining us in the next film."

Without an official cast list or plot synopsis for the film, only a handful of actors have been known to be confirmed for "Civil War" prior to this point. It's been known that Evans would be joined by Downey Jr., and Chadwick Boseman will also make his debut as Black Panther in the film. Comments made by Anthony Mackie in interviews earlier this week confirm that the Falcon will also return.

Considering how prominent her role was in last year's "Captain America: The Winter Soldier," it had been assumed -- but not confirmed -- that Johansson would return for the follow-up installment; the same goes for Sebastian Stan's Winter Soldier. Johansson will next be seen as Black Widow this May in "Avengers: Age of Ultron." An appearance in "Civil War" will mark Johansson's fifth outing as Natasha Romanoff.

"Captain America: Civil War" opens on May 6, 2016. You can watch the Russo's full interview below.
