Stewart spoke with Oregon Live where he also confirmed Ian McKellen's Magneto will appear in X-Men: Apocalypse.
Yes, I understand that it seems to be very unlikely that I will be in the next "X-Men" movie, which is almost getting ready to start shooting in Montreal.
[LAUGHS] But Magneto, Ian McKellen, is certainly going to be in it. And what I'm very excited about is that we have been talking about a Wolverine movie, which would team Hugh Jackman and myself together. Wolverine and Professor Xavier. That would be a very different sort of "X-Men" from the four movies that I've already done.
Fox has slated the next Wolverine movie for a March 3, 2017 release, which will see James Mangold return to direct.
The Wolverine made over $400 million in 2013.
X-Men: Apocalypse has a May 27, 2016 release.
