Evans first tells Esquire that filming on Captain America: Civil War will go to August or September, and Evans also says he expects filming on the two Avenger: Infinity War movies to start either in the fall or winter of 2016:
"You know, you plan around the Marvel responsibilities. You have to. We start [Captain America: Civil War] in a couple weeks, and then that shoots until August or something like that. August or September. Then I've got some downtime and I can do with it as I please. I don't know if I want to take time off or go pursue another directing job or find a movie to act in or, you know, do whatever I'm creatively inclined to pursue or wait, relax, enjoy my life. And then we start the Infinity War, I think, some time in the third quarter. Fall or winter of 2016. That's going to be like nine months to shoot both movies back to back."
Regarding Captain America 3, Evans just tweeted he had to shave his beard for the movie as filming looks to begin any day now.
Avengers: Infinity War Part 1 has a May 4, 2018 release date; Avengers: Infinity War Part 2 opens a year later on May 3, 2019.
