Oscar Isaac set to play the bad guy in 'X-Men: Apocalypse'

Oscar Isaac will be playing the titular villain role in 'X-Men

According to the Hollywood Reporter, the latest X-Men installment, which would see Bryan Singer return to the director's chair, would star the 35-year-old 'Inside Llewyn Davis' as Apocalypse, the character which was seen in a coda during 'Days of Future Past'.

The character was born in the ancient Middle East and is shown as a gray-skinned immortal with a host of powers ranging from super-strength to telepathy to morphing his body's form and size.

Singer had worked on the story with Michael Dougherty, Dan Harris and Simon Kinberg, who's also writing the script, and while 'Days of Future Past' was set in the 1970's, this film would be set in the 1980's.

The movie would see Michael Fassbender, James McAvoy and Jennifer Lawrence return to their roles, while actors to play young versions of Cyclops and Jean Grey/Marvel Girl are still to be cast.

The film, which would begin production early in 2015 with Fox, is anticipated to release in May 2016.
