Not too much is known about James McAvoy's role in X-Men: Dark Phoenix just yet but the film will adapt the classic X-Men storyline from the comics, wherein Jean Grey is possessed by a cosmic entity called the Phoenix Force, drastically boosting her powers and sending her on a rampage throughout the galaxy. The film will supposedly introduce the Shi'ar Empire, a group of powerful aliens who decide to end the Phoenix Force once and for all. Xavier has a romance with the Shi'ar's empress Liliandra, but seeing as how that character is reportedly a villain in the film (with Jessica Chastain rumored for the part), it remains to be seen if McAvoy will be able to get his flirt on.
