According to producer Simon Kinberg, Charles Xavier will be in the planned New Mutants movie if and when it hits the big screen.
Speaking to Collider, Kinberg — who wrote and produced X-Men: Apocalypse — said, “Right now, as the movie exists, Professor X would be a part of a New Mutants movie.” He also he hopes New Mutants will begin shooting in early 2017.
It’s unclear how many characters from the previous X-Men movies may have roles in New Mutants, or whether James McAvoy will be reprising his role as Professor X in the movie.
This lines up with what Kinberg recently told ComingSoon.net. When asked about the follow-up to X-Men: Apocalypse, Kinberg said, “The next one is set in the ’90s.” Considering when New Mutants begins filming, it seems likely he’s referring to that film.
