Anya Taylor-Joy and Maisie Williams have been cast in Fox and Josh Boone’s upcoming X-Men film New Mutants.

According to The Hollywood Reporter, director Josh Boone had been aiming to cast the ladies since last year, but he couldn’t move forward until recently when the studio greenlit the project. As for their roles?

Taylor-Joy will play Magik, a girl who has learned sorcery and uses teleportation discs to travel. She is also the sister of Colossus, an X-Man who appeared in Deadpool.

Williams will play Wolfsbane, a girl struggling to reconcile her religious beliefs with her power to turn into a wolf.

Maisie Williams is best known for her role in Game of Thrones, while Anya Taylor-Joy co-starred in The Witch and Split.

New Mutants will hit theaters April 13, 2018.
