Legion is an American cable television series created for FX by Noah Hawley, based on the Marvel Comics character David Haller / Legion. It is connected to the X-Men film series, the first television series to be so, and is produced by FX Productions in association with Marvel Television. Hawley serves as showrunner on the series.
Dan Stevens stars as Haller, a mutant diagnosed with schizophrenia at a young age. Rachel Keller, Aubrey Plaza, Bill Irwin, Jeremie Harris, Amber Midthunder, Katie Aselton, and Jean Smart also star. FX and Marvel Television announced a new collaboration to create a television series based on the X-Men character Legion in October 2015, with Hawley signed on to write, and direct the pilot. Casting began by January 2016, and filming took place in Vancouver. Hawley wanted to show Haller as an “unreliable narrator”, including mixing 1960s design with modern-day elements, and filming the series through the title character’s distorted view of reality.
The eight-episode first season of Legion premiered at the Pacific Design Center on January 26, 2017, ahead of its FX debut on February 8. The series received critical acclaim, particularly for its visuals and departure from superhero genre standards. A second season, of ten episodes, was ordered in March 2017 and is planned for a February 2018 release.
