In an interview with ComicBook.com, Avengers: Infinity War co-director Anthony Russo talked a bit about what we can expect out of Infinity War, specifically that the story will be told from multiple perspectives that will include every established MCU character:
“It’s a culmination of everything that’s occurred in the Marvel Universe up to the point where the Marvel Universe is released. Some of those films haven’t even hit yet. We’re going to be dealing with some of the characters from those movies who are going to be in Infinity War. They’re massive in scope and scale but that’s the point. The point is for them to be as ambitious as they possibly can be. They’re going to be multi-perspective films. They’re not called ‘Captain America: Infinity War,’ they’re called Infinity War. You’re going to be moving around through different perspectives of the characters. It’s like Nashville for super heroes. It’s storytelling that is vignetted storytelling. It’s to composite all of them under one story – everybody. You can culminate without all of them, so…”
We have yet to see some of the future players that will be involved in Infinity War (such as Captain Marvel), so to what extent we’ll see each character has yet to be determined. We also may see some characters from the Marvel TV Universe (Daredevil, Jessica Jones, Punisher, Luke Cage, etc). Daredevil star Charlie Cox recently stated:
“When I signed the contract for the show, I signed multiple years for Daredevil and, of course, The Defenders, and in that package there was the opportunity to be involved in the movies in some way.”
Captain America: Civil War hits theaters May 6, 2016. Avengers: Infinity War Parts I and II hit theaters May 4, 2018 and May 3, 2019, respectively.
