The X-Men are forced to confront an ancient mutant called Apocalypse (Oscar Isaac) in this comic-book adventure set in the 1980s. Eager to take over the world and remake it in his own image, Apocalypse recruits mutants to act as his powerful "Four Horsemen" -- among them is the tortured Magneto (Michael Fassbender), who believes humanity might be a lost cause after a personal tragedy. In time, Charles Xavier (James McAvoy) and his charges must work together to save the planet from this threat. New additions to this X-Men team include the elusive Nightcrawler (Kodi Smit-McPhee), fiery Cyclops (Tye Sheridan), and telepathically gifted Jean Grey (Sophie Turner). Rose Byrne, Jennifer Lawrence, and Olivia Munn co-star.
