Game of Thrones Alum Harry Lloyd to Play Charles Xavier in Legion

Professor X and Gabrielle Haller are set to appear in the final season of Legion. The show’s official Twitter account announced on Monday that Harry Lloyd (Game of Thrones and Stephanie Corneliussen (Mr. Robot) will play the two Marvel characters, who also happen to be David Haller’s parents, in the show’s third season. Charles Xavier will make his debut in the third episode.

Lloyd is best known to fans by a much more (or somewhat more, for those of us who know what an unethical jerk Xavier is in the comics) amoral role in Game of Thrones as Viserys Targaryen, Daenerys’ brother. He currently plays Peter Quayle in Starz’ Counterpart.

Legion returns for its third — and final — season in June.
