THR reports Chastain will play the villain in the film, and again it's exactly the role I suggested, that of Shi'ar empress, Lilandra. The Shi'ar are an alien race who view the Dark Phoenix as a harbinger of death too powerful to exist in the universe. That puts them at odds with Xavier (James McAvoy, reuniting with Chastain after The Disappearance of Eleanor Rigby) and the X-Men who are looking to protect Jean Grey, played by Sophie Turner. Interestingly, Jennifer Lawrence, Michael Fassbender,and Nicholas Hoult are all coming back after they had one foot out the door. Alexandra Shipp, Tye Sheridan, and Kodi Smit-McPhee will also reprise their roles.
Very cool. X-Men: Dark Phoenix opens November 2nd 2018 with Simon Kinberg directing.
