10 Biggest Mysteries Surrounding 2016's Biggest Movies

9. How Will Charles Xavier Lose His Hair? - X-Men: Apocalypse

Admit it: haven't you just been dying to know how the X-Men movies would ultimately address this subject given that James McAvoy has remained rather hairy over the span of his many appearances playing a younger version of the iconic Marvel character? Well, X-Men: Apocalypse is set to reveal the answer to the long-standing question that is... when will Professor Charles Xavier lose his hair? Fans have been long awaiting the moment whereupon McAvoy begins to resemble Patrick Stewart, of course, and based on set photos which show the actor lacking any follicles atop his head, it looks like the time has come. The biggest mystery of all, though, concerns how exactly the character will wind up going bald. Fans are certainly hoping for something a tad more interesting than "oh, it just happened with old age," because after so many years such a revelation would likely wind up disappointing a lot of people. Fingers crossed they've come up with something cool.
