During the 2012 Montreal Comic Convention, a fan asked Sir Patrick Stewart if he would be returning to the X-Men series, the actor replied, “I think there is every possibility,” and then began to give
names of his female co-stars “Halle Berry! Famke Janssen! Rebecca Stamos! Anna Paquin!” Finally Stewart said, “Yes, I’ll be reprising…” as professor Charles Xavier.
So far the only upcoming film of the franchise is X-Men: Days of Future Past. On August 01, Brian Singer confirmed that the sequel for X-Men: First Class was officially titled X-Men: Days of Future Past.
Singer told IGN, “It’s called ‘Days of Future Past (…) It deals with aspects of that comic, but also some very new things.”
For those that don’t know much about Days of Future Past, the storyline is an alternate future for Marvel’s mutants that occurred thanks to the Brotherhood of Evil Mutants after killing an important senator, thus leading to a future where all mutants are hunted by Sentinels.
