Jessica Chastain may be taking a page out of old friend and classmate Oscar Isaac's book to play a villain in the next "X-Men" movie.

The actress is reportedly in talks to join "X-Men: Dark Phoenix" as the main villain, Lilandra, the empress of an alien empire called the Shi'ar.

The movie has also officially tapped Simon Kinberg, a longtime franchise writer and producer, to make his directorial debut.

"X-Men: Apocalypse" stars Jennifer Lawrence, Michael Fassbender, James McAvoy, Nicholas Hoult, Alexandra Shipp, Tye Sheridan, and Kodi Smit-McPhee are all reprising their roles.

Sophie Turner will also return as Jean Grey, who will be the focus of the movie. In the comics, Jean's powers are hugely amplified when she comes into contact with a cosmic energy called the Phoenix Force. It takes over her personality and turns her into the evil Dark Phoenix, a foe that the X-Men must band together to defeat.

The Dark Phoenix was incorporated into "X-Men: Last Stand," though it was a split personality that Professor Charles Xavier embedded into Jean's subconscious.

"X-Men: Dark Phoenix" is in preproduction and scheduled for release Nov. 2, 2018.
