In an interview with IGN, Producer Bryan Singer has validated a rumor that has been floating around for about a week now and officially confirmed that the title of the sequel to X-Men: First Class will be X-Men: Days of Future Past.

If you are a longtime fan of the X-Men comics, or were at least a fan in the early 80s, you likely recognize the name as it comes directly from one of the series’ most famous storylines. The filmmakers using it is good news at first glance—until you realize that the story featured time travel and the death of most of the X-Men, as well as an extremely convoluted plot thread that revolved around the daughter of Cyclops and Jean Grey from an alternate timeline, who was followed into the past by a super sentinel and later by another super villain named Ahab, who may or may not have altered his own past by merging with his past self—it quickly got complicated. The storyline itself would almost certainly never be directly attempted on the big screen. Fans might love it, but most audiences would be lost. 

But there is a lot that could be taken from that story arc that would make for a good, maybe even incredible movie. One of the main points of “Days of Future Past” was the rise of the sentinels, robotic machines created specifically to combat mutants. The sentinels are one of the X-Men’s greatest threats, as well as a longtime fan favorite, and their absence from the series thus far–with the exception of a brief training sequence in X-Men: Last Stand that may have been a sentinel (see above image)–has been a notable absence.

If the sentinels are introduced—and it seems likely as the “Days of Future Past” storyline was all about the sentinels hunting mutants–it stands to reason that the film will also deal with the anti-mutant hysteria that has always been a part of the X-Mean comics, especially during the 80s. That also raises the question of when the film will be set, but no word on that yet.

Filming will begin in January of 2013. The production was pushed back into next year to accommodate the schedule of Jennifer Lawrence, who is currently deep into production for The Hunger Games: Catching Fire. X-Men: Days of Future Past is then scheduled for release after a lengthy production period, and is slated for release on July 18, 2014.
