Williams' on-screen sister, Sophie Turner (Sansa in "Game of Thrones), is already exercising her mutant powers as Jean Grey, who will get her own standalone movie in "Dark Phoenix," due out November 2, 2018.
In "New Mutants," Anya Taylor-Joy will play Williams' fellow mutant, Magik (aka Illyana Rasputina). Director Josh Boone, who also directed "The Fault in Our Stars," co-wrote the script with Knate Gwaltney based on the Marvel comic first published in 1982. Look for plenty of other young stars to join, as Entertainment Weekly sources say the movie will have a "John Hughes meets Stephen King" vibe.
Williams and Turned will return in the "Game of Thrones" seventh season, premiering July 16 on HBO. Too bad the sisters Stark couldn't have even a few of their mutant powers to fight Cersei Lannister back in Westeros.
