Sophie Turner, Tye Sheridan and Alexandra Shipp have joined the cast of Fox’s “X-Men: Apocalypse.”

Turner will play Jean Grey, Shipp will portray Storm, and Sheridan will play Cyclops.

Bryan Singer tweeted the news of the castings on Thursday.

Singer is directing. Plot details are unknown.

Singer had been testing actors and actresses for the last couple of weeks, and sources indicated that Sheridan blew Singer away early on.

Oscar Isaac was previously cast as the titular villain in the comicbook movie. “X-Men” veterans Jennifer Lawrence, James McAvoy and Michael Fassebender will return for the next installment.

The pic bows on May 27, 2016.

Sheridan can be seen next in the Sundance pic “The Stanford Prison Experiment,” and Turner continues to appear on HBO’s “Game of Thrones.” Shipp can be seen next in “Straight Outta Compton.”

Sheridan is repped by WME and Mosaic, Turner by CAA and Independent Talent Group and Shipp by Osbrink Talent Agency and Elevate Entertainment.
