According to MTV on Friday, "X-Men: Days of Future Past's" Patrick Stewart, also known for his role as Captain Jean-Luc Picard from "Star Trek: The Next Generation" may have revealed a spoiler to the mutant enriched film. During the interview when asked if Professor Charles Xavier would be returning for "X-Men: Apocalypse" Stewart mentioned a little bird could have told him something because after all in science fiction no one is ever truly dead.
If any fan remembers and perhaps stayed up until the post-credit ending of "X-Men: The Last Stand", Xavier had transferred his mind into the body of a comatose patient prior to his death at the hands of Jean Grey. Dr. Moira MacTaggert was attending when Professor X spoke to her at his bedside.
If one digs even further, MacTaggert attended his memorial service as she was seated next to Beast. She was also seen talking about the complexities of mutant abilities and gave an example of mind transference that could be accomplished by a telepathic mutant. Obviously, she was able to have her theory proven by this post-credit tease. The amusing thing about this that Stewart mentions he's encountered fans that never stuck around for that scene.
That being said, he also talked about how they had left it rather open for Magneto and Xavier's return after all, while in the park Magneto was playing chess with metal pieces. He had made a rather weak attempt at trying out his powers once again only to slightly move the metal chess marker which was a scene that was probably most seen by audiences.
When Stewart was questioned about how he reacted to finding out he was coming back to play the role once again, he said he had been hoping to get the call. He mentioned talking on the phone with "Ian" about having taken on the role.
"X-Men: Days of Future Past" premieres May 23.
