The Simon Kinberg-directed movie is expected to be a more faithful adaptation of The Dark Phoenix Saga comic book series. It is believed that the film will take place in the 1990s, and will feature James McAvoy (Charles Xavier), Nicholas Hoult (Beast), Jennifer Lawrence (Mystique), Alexandra Shipp (Storm), Kodi Smit-McPhee (Nightcrawler), and Evan Peters (Quicksilver) all reprising their roles in X-Men: Apocalypse, and beyond.
Dark Phoenix has encountered a number of roadblocks en route to its February 14, 2019 release date. The film was originally slated for a November 2, 2018 release, but that was changed back in March.
