After director Josh Boone teased the roster of 20th Century Fox's New Mutants film, producer Simon Kinberg has confirmed that Professor X will also be a part of the film as it stands now.
“Right now, as the movie exists, Professor X would be a part of a New Mutants movie," Kinberg told Collider.
Barring any changes to the script that might drop the character, the next question is 'Which Professor X?' The film is assumed to be set in modern-day, leading to Patrick Stewart being the obvious choice, but the lack of a specific timeline could open the door for James McAvoy to possibly play a role. Stewart is already confirmed as reprising the role of Xavier in 2017's Wolverine 3.
20th Century Fox hasn't yet announced the release date of New Mutants.
