The movie's international debut represents 64% of the worldwide marketplace, with key openings in Korea on May 25, North America on May 27, China on June 3 and Japan on August 11. X-Men: Apocalypse marks the end of the studio's prequel trilogy, following 2011's X-Men: First Class and 2014's X-Men: Days of Future Past. The story is set in 1983, 10 years after the events of X-Men: Days of Future Past. Last week, as the movie was opening internationally, new details were teased about the post-credit scene, which introduces a character from the Marvel Comics, Mister Sinister.

The story follows beloved mutants Professor X (James McAvoy), Mystique (Jennifer Lawrence) and Beast (Nicholas Hoult), who join forces with a number of young mutants to stop the villainous Apocalypse (Oscar Isaac). Apocalypse is the first and most powerful mutant from Marvel's X-Men universe, who has amassed the powers of many other mutants, becoming immortal and invincible. Upon awakening after thousands of years, he is disillusioned with the world and recruits a team of powerful mutants, including a disheartened Magneto (Michael Fassbender), to cleanse mankind and create a new world order, over which he will reign.

As the fate of Earth hangs in the balance, Raven (Jennifer Lawrence), with the help of Professor X (James McAvoy), must lead a team of young X-Men to stop their greatest nemesis and save mankind from complete destruction. Reprising their roles from X-Men: First Class and X-Men: Days of Future Past are Nicholas Hoult (Beast), Rose Byrne (Moira McTaggert), Evan Peters (Quicksilver). New cast members include Oscar Isaac as the villainous Apocalypse, Olivia Munn as Psylocke, Sophie Turner as Jean Grey, Alexandra Shipp as Storm, Tye Sheridan as Cyclops and Kodi Smit-McPhee as Nightcrawler. The movie will also mark the long awaited return of Hugh Jackman as Wolverine! Be sure to check back all this week for more updates on X-Men: Apocalypse before it opens in theaters May 27.
