X-Men: Apocalypse will be set in the 1980s! After months of speculations, we are finally sure of this fact. With X-Mne: First Class set in the 1960s and X-Men: Days of Future Past set in the 1970s, it was speculated that the upcoming film might be set in the 1980s, but with the franchise and time-travel, you never know!
It was only when producer and writer Simon Kinberg teased a set photo of a theatre screening the Return of the Jedi that the fans were finally sure about the said time period. The production has started in Montreal, Canada and the glimpse of the actors and their jackets have confirmed that the film has gone back to the 80s this time.
There was an end credit teaser in the last film, X-Men: Days of Future Past that showed a blue boy using his psychic powers to build the pyramids, with the shadow of the Four Horsemen looming large in the background. This character, Apocalypse is set to be the villain in X-Men: Apocalypse. The role of Apocalypse will be portrayed by Oscar Isaac of The Force Awakens and Ex Machina.
X-Men: Days of Future Past changed a lot of things in the X-Men history. This will impact how and when certain characters make an entry in X-Men: Apocalypse. Since the characters of Kitty Pryde (Ellen Page) and Beast (Kelsey Grammer) survived, we will see them in this film as well. We also see Professor X (James McAvoy), Mystique (Jennifer Lawrence), Magneto (Michael Fassbender) returning.
Apart from the old X-Men members, we have X-Men introducing younger versions of characters who have been seen in the earlier films to understand their initial days as -Men. Sophie Turner plays the younger Jean Grey, Tye Sheridan replaces James Marsden as Cyclop and Alexandra Shipp is Storm. Olivia Munn as Psylocke and Kodi-Smit McPhee as Nightcrawler will be joining X-Men: Apocalypse.
