Actor James McAvoy, who plays Charles Xavier/Professor X in the nu-X-Men movie franchise, told HuffPo that the only thing he knows about his character in the upcoming, 1980s-set sequel Apocalypse that he believes he's "losing my hair finally." So check that off the list of cinematic X-universe discrepancies.
I wonder how he'll lose it. Will he just show up and be bald? Will it be because of regular old aging, or because his telepathic powers are so strong they push the hair out of his head? Will it be cause of some sort of lab accident with Superboy causing him to vow vengeance against the Man of Steel? I have to admit, that last one would be quite the twist.
