Fox has released the first clip from "X-Men: Apocalypse," one that runs through the movie origin behind the ancient villain. Much of this scene has been used in previous trailers, mostly as a voiceover as C.I.A. agent Moira MacTaggert (Rose Byrne) explains what she knows about the ancient villain Apocalypse to Xavier (James McAvoy) and Havok (Lucas Till).

Directed by Bryan Singer and starring James McAvoy, Michael Fassbender, Nicholas Hoult, Jennifer Lawrence, Oscar Isaac, Rose Byrne, Alexandra Shipp, Sophie Turner, Kodi Smit-McPhee, Evan Peters, Tye Sheridan and more, "X-Men: Apocalypse" opens on May 27, 2016.
