Another Marvel hero is making its way to the small screen! FX Networks has ordered eight episodes of the first season of the X-Men-themed pilot Legion series. We’ve gathered what we know so far about the exciting new show.

What Legion is about

According to Deadline, the Legion series centers on the story of a troubled young man who turns out to be more than just an average human being. At the heart of the story is David Haller, who has suffered from mental illness ever since he was a teenager. He is diagnosed with schizophrenia and has been in and out of psychiatric hospitals. After meeting a fellow patient, Haller soon discovers that the vision he sees and the voices he hears are not just mere hallucinations, but are actually very real.

Who is Legion in the X-Men comic books?

In the Legion comics, David Haller is the son of Professor Charles Xavier.

He is known as one of the most powerful mutants. But due to the nature of his powers, he’s also one of the most unstable and the most dangerous mutants.

Downton Abbey star takes the main lead

Playing David Haller is British actor Dan Stevens. Viewers may know him as Matthew Crawley in Downton Abbey and Beast in the upcoming live-action adaptation of Beauty and the Beast.

Also joining the Legion cast are Rachel Keller, Jean Smart, Aubrey Plaza, Jeremie Harris, Bill Irwin, Katie Aselton, and Amber Midthunder.

The project is helmed by Fargo and X-Men creators

The creative teams from Fargo and X-Men will join forces for Legion. Fargo’s  Noah Hawley and John Cameron are on board as executive producers together with X-Men: Days of Future Past producers Bryan Singer, Lauren Shuler Donner, and Simon Kinberg. SpoilerTV reported that the geniuses behind Marvel’s Daredevil, Jessica Jones, and Agents of S.H.I.E.L.D. Jim Chory and Jeph Loeb, will also executive produce.
