Despite Tim Story's two Fantastic Four movies of the 2000s both featuring space-travel and/or aliens, Twentieth Century Fox has oddly neglected to take its X-Men franchise to the stars. Looking back now from 2016 it seems a lost opportunity for the long-running and successful superhero franchise, especially given the number of cosmic characters from Marvel Comics that Fox owns the rights to.
Many classic X-Men comic book stories and iconic characters hail from space - including and perhaps most infamously, the Phoenix - but the live-action movies haven't dug into that lore. Not yet anyway, but's likely going to change. Marvel Studios successfully expanded their shared universe into other worlds with the Thor movies and Guardians of the Galaxy, and Warner Bros./DC Entertainment are doing the same - with Man of Steel having kicked off a DC movie universe with an alien introduction that will ultimately lead to the Green Lantern Corps.
The still-running X-Men series though, having beaten both of those other studios to the shared universe front by many years, is behind the ball but we have a feeling director and producer Bryan Singer may help change that. Back when he was working on X-Men: Days of Future Past and teasing that its followup would be X-Men: Apocalypse, Singer said that he and the creative teams working on Fox's Marvel properties see more value than ever in the properties they own - and will start to take advantage of that vast library of stories and characters available to them.
X-Men: Days of Future Past introduced time-travel into the X-Men movies lore, thus allowing the studio to (essentially) infinitely reboot the series while keeping it all within canon. And when our own Andrew Dyce visited the set of X-Men: Apocalypse in July, Bryan Singer said this next one introduces the "origins of the mutant state, or the origin of gods and religion." But it may also help the X-Men take their first step into the "cosmic" - a word used by writer/producer Simon Kinberg last summer, several months after Singer shared this very alien looking concept art:
