In the upcoming X-Men: Apocalypse, the primary villain will be the titular Apocalypse (Oscar Isaac), an immortal mutant who recruits four mutants to serve as his personal guard, known as the "Four Horsemen." We've known for a while that those roles will be filled by Psylocke (Olivia Munn), Storm (Alexandra Shipp), Angel/Archangel (Ben Hardy) and Magneto (Michael Fassbender).
In a newly-published interview at ScreenRant, director Bryan Singer explained that the so-called "Four Horsemen" would be somewhat different than how they've traditionally been portrayed in the Marvel comic books. For one thing, instead of being renamed as War, Death, Famine and Pestilence, with powers to match, the movie will keep their original character names. For another, taking a cue from real-life cult leaders who attract different factions of followers, the individual mutants will represent political, military, youth and sexual factions.
New photos of the "Four Horsemen" have also been released. Psylocke and Storm are teamed up above; below are Storm, Angel/Archangel and Magneto.
Meanwhile, writer/producer Simon Kinberg talked about plans for the X-Men movie universe, as reported by JoBlo. Changes in the timeline mean that some characters who appeared in the original trilogy of movies (X-Men, X2 and X-Men: The Last Stand) might not survive in the new series.
As to how the spin-off movies fit into the X-Men universe, Kinberg said: "They all are part of a larger fabric now, and so the world of Deadpool, the world of Gambit, exists in a post-Days of Future Past, post-Apocalypse world where all of these stories are the same as our shared history. … our fictitious events, like the stadium dropping on the White House in 1973, is part of the world in which Gambit, Deadpool, Wolverine" exist.
Here's a recap, via Cinema Blend, of when we can expect the spin-off movies: Deadpool arrives in theaters on February 12, Gambit on October 7 (though that date could change), Wolverine 3 on March 3, 2017 and New Mutants sometime after that.
The conclusion of the current trilogy, X-Men: Apocalypse, will open in theaters on May 27.
