'X-Men: Days of Future Past' Photos

Over the course of production and promotional campaigning, loads of 'X-Men: Days of Future Past' photos have come courtesy of 20th Century Fox and director Bryan Singer, the latter of who has been keeping fans up to date throughout the entire process. Much like the grandiosity of the cast, we've compiled a massive photo gallery of all the latest stills and behind-the-scenes pictures from the upcoming sequel to Matthew Vaughn's 'X-Men: First Class.'

Hugh Jackman, who's reprising his role as Wolverine for the seventh time (if you include his cameo in 'First Class'), describes 'X-Men: Days of Future Past' as three movies in one, which is no exaggeration. The photos released from the superhero team-up feature casts from both the original X-Men trilogy (like Patrick Stewart, Ian McKellen and Halle Berry) and the 'First Class' run (like James McAvoy, Michael Fassbender and Jennifer Lawrence), as well as some newcomers, including 'Game of Thrones' star Peter Dinklage as comic book villain Bolivar Trask.

As the 'X-Men: Days of Future Past' photos preview, the film takes its name from the classic comic book story arc, in which the X-Men are living in an apocalyptic future where mutant-hunting Sentinel robots dominate Earth. To prevent this future from existing, Wolverine is sent back in time to warn the X-Men of the past of the life-altering event that sets it all in motion.

The film is set for release on May 23, 2014, but until then, take a look at the latest 'X-Men: Days of Future Past' photos below.
