‘Legion’ Casts Legion’s Dad (AKA Professor X) and Mom for Final Season

Stephanie Corneliussen and Harry Lloyd to guest star as David Haller’s parents

“Legion” has found David Haller aka Legion’s parents. Stephanie Corneliussen and Harry Lloyd have been set as guest stars for the Noah Hawley-created FX series upcoming third and final seasons, playing Gabrielle Haller and Professor X, respectively.

The casting news was revealed Monday via the show’s official Twitter account, in a tweet that read: “Noah Hawley is pleased to announce two guest castings for the final year of #LegionFX. Stephanie Corneliussen will play David Haller’s mother, “Gabrielle,” and Harry Lloyd will play his father, ‘Professor X.'”

Earlier Monday, FX CEO John Landgraf told reporters during the  Television Critics Association press tour that the “X-Men” drama would be concluding after its upcoming third season. FX boss said Hawley, who created the drama, had always planned for it to be a three-season story. The final season will premiere this summer.

“Legion” is based on the Marvel comics by Chris Claremont and Bill Sienkiewicz and stars Dan Stevens as David Haller, a man who thought he was schizophrenic but is actually a powerful mutant. Season 2 saw David take on the Shadow King, aka Amahl Farouk (Navid Negahban), a parasite that has been haunting David since he was a kid. The drama also stars Rachel Keller, Jean Smart, Jeremie Harris, Amber Midthunder, Bill Irwin, Aubrey Plaza and Jemaine Clement.

The show is executive produced by Hawley and John Cameron, Lauren Shuler Donner, Simon Kinberg and Jeph Loeb. Writer Nathaniel Halpern co-executive produces. The drama hails from FX Productions and Marvel Television, with FXP handling the physical production.

The news of “Legion” coming to an end comes as other Marvel TV series are winding down, especially on Netflix. “Legion” was a co-production with 20th Century Fox, as Fox held rights to “X-Men” properties. Three of Marvel TV’s series on Netflix — “Luke Cage,” “Daredevil” and “Iron Fist” — have been canceled, while ABC (which, like Marvel, is owned by Disney) has at least two more seasons of “Agents of S.H.I.E.L.D.” planned.
