Legion is an upcoming American cable television series created for FX by Noah Hawley, based on the Marvel Comics character of the same name. It is connected to the X-Men film series, the first television series to do so, and is produced by FX Productions in association with Marvel Television and 26 Keys Productions. Hawley serves as showrunner on the series.
Dan Stevens stars as David Haller, a mutant diagnosed with schizophrenia at a young age. Rachel Keller, Jean Smart, Aubrey Plaza, Jeremie Harris, Amber Midthunder, Katie Aselton, and Bill Irwin also star. In October 2015, FX and Marvel Television announced a new collaboration to create a television series based on the X-Men character Legion, with Hawley signed on to write and direct the pilot. Casting began by January 2016, and the pilot was completed by May. The show was then picked up to series. Filming takes place in Vancouver, and on sets built in Burnaby. 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.
