Dan Stevens stars as David Haller in Legion

Marvel has announced that FX Networks has ordered the first season of Legion. The story follows a troubled young man who may be more than human. For comic fans, the character Legion has traditionally been David Haller, the son of Professor Charles Xavier and Gabrielle Haller. It’s unknown how much the show may tie into the various X-Men films.

The cast for the show’s cast includes Dan Stevens (“Downton Abbey”), Rachel Keller (“Fargo”), Jean Smart (“Fargo”), Aubrey Plaza (“Parks and Recreation”), Jeremie Harris (“A Walk Among the Tombstones”), Amber Midthunder (“Hell or High Water”), Katie Aselton (“The League”) and Bill Irwin (“Interstellar”).

Production on the eight-episode first season will begin this summer in Vancouver and the new series from FX Productions and Marvel Television will debut on FX in early 2017.

Below is the description released for the show.

“Legion” introduces the story of David Haller: Since he was a teenager, David has struggled with mental illness. Diagnosed as schizophrenic, David has been in and out of psychiatric hospitals for years. But after a strange encounter with a fellow patient, he’s confronted with the possibility that the voices he hears and the visions he sees might be real.
