The 72-year-old actor, who has portrayed the character in five "X-Men" movies, said he will be playing the alter-ego again, reported Contactmusic. "I think there is every possibility.
Yes, I'll be reprising," he said. Actor James McAvoy recently took on the role of Professor X - whose real name is Professor Charles Xavier - in last year's "X-Men: First Class" movie.
The sequel, 'X-Men: Days of Future Past', is expected to be based on a storyline from the famous comic of the same name. The original two-issue comic features time travel, which could be a way of both Stewart and McAvoy reprising the part of Professor X in the forthcoming film, due to be released in 2014 and stars Jennifer Lawrence and Michael Fassbender. McAvoy has already signed up for the role again, but there is no word on whether Stewart will be starring as the character in the movie.
