Writer-director Simon Kinberg explains that Xavier puts the team on more and more dangerous missions, culminating in a space rescue mission gone awry, where a solar flare awakens Jean Grey (Sophie Turner's) dark inner force, the Phoenix.
Drawn in part from the original 'Phoenix' comic storyline, the film will apparently be the most sinister and somber entry in the series, and includes a "massive twist halfway through that will irrevocably change the course of the franchise," according to EW.Aside from Turner and McAvoy's characters, we'll see the return of Mystique (Jennifer Lawrence), Beast (Nicholas Hoult), Storm (Alexandra Shipp), Nightcrawler (Kodi Smit-McPhee), and Quicksilver (Evan Peters). Jessica Chastain will also play a shapeshifter that meets Phoenix.
X-Men: Dark Phoenix will be released on November 2, 2018 - but there's a lot more X-Men centric stuff coming to our screens in the next few years. Joe Skrebels is IGN's UK News Editor, and is a twist a twist when you tell everyone there's a twist? Follow him on Twitter.
