Jean Grey is a member of the X-Men, and has been included in almost every media adaptation of the X-Men franchise, including film, television and video games.
Two incarnations of Jean Grey appear in the X-Men film series, portrayed by Famke Janssen and Sophie Turner.
Throughout the films X-Men (2000), X2, and X-Men: The Last Stand, the first incarnation serves as a member of the X-Men until she is possessed by the Phoenix Force and killed by Wolverine.
Additionally, she makes minor appearances in The Wolverine, in which her death haunts the titular character, and X-Men: Days of Future Past, in which she was revived after the X-Men averted a post-apocalyptic future.
In the films X-Men: Apocalypse and Dark Phoenix, the second incarnation joins the X-Men to fight Apocalypse before sacrificing herself to use the Phoenix Force's power to defeat the D'Bari.
