With Marvel's intertwining storylines and constant introductions of new landmark characters, everyone assumes the films will just keep chugging along indefinitely.
After Phase 3 though, the Marvel Universe will hit a bit of a checkpoint, and things might look a lot different in Phase 4 according to Marvel Studios President Kevin Feige.
“I think you look at comics as a guide,” Feige tells EW. Although certain titles may get relaunched or rebooted, the narrative exists on a never-ending continuum."
“I think there will be a finality to moments of Phase Three, as well as new beginnings that will mark a different, a very different, a distinctively different chapter in what will someday be a complete first saga made up of three phases,” Feige said."
That statement implies that some of these heroes we've grown to love might not be as involved as they were in the first few phases. Either that or maybe some will just look a bit different, played by different actors. Joe Russo doesn't really dive into all that, but he does address how Captain America: Civil War will begin that march to a new and different Marvel Universe.
“Things always get deconstructed, right?” says Joe Russo. “You build things up and people enjoy the experiences you’ve built up. But then you kind of reach an apex or you reach a climax, a moment where you go, ‘This structure is really going to start to be repetitious if we do this again, so what do we do now?’ So now, you deconstruct it. We’re in the deconstruction phase with Civil War and leading into Infinity War, which are the culmination films.”
Lots of questions and not enough answers, but first we have to get through Civil War, which opens on May 6th.
