Watch: X-Men Fight One Of Their Own In New ‘X-Men: Dark Phoenix’ Trailer

Jean Grey goes full-on villain

Fox has just released the first trailer for what will be the final X-Men franchise film under the studio’s banner, X-Men: Dark Phoenix.

In the newest film in the series, the X-Men will have to go up against one of their own, Jean Grey (Sophie Turner). The trailer highlights Jean’s traumatic childhood, which gives us a glimpse into her capability of hurting the people around her as she struggles to keep her powers in check.

Check out the trailer below.

Jennifer Lawrence, Michael Fassbender, and James McAvoy return as Mystique, Magneto, and Professor X respectively, but a quick shot of a funeral scene in the trailer hints that perhaps not all three mentors will make it out of the film alive.

Writer and director Simon Kinberg is hoping to stay true to the comic books by making the Phoenix a force that gives Jean both power and instability.
