Legion (season 2) The second season of the American cable television series Legion is based on the Marvel Comics character David Haller / Legion, a mutant diagnosed with schizophrenia at a young age. The season is produced by FX Productions in association with Marvel Television. Noah Hawley serves as showrunner. Dan Stevens stars as Haller, with Rachel Keller, Aubrey Plaza, Bill Irwin, Jeremie Harris, Amber Midthunder and Jean Smart also returning from the first season to star. They are joined by Jemaine Clement and Hamish Linklater, promoted from guest roles in the first season, and Navid Negahban. A second season of Legion was ordered by FX in March 2017, with filming for the season relocating from Vancouver to California, to take advantage of tax incentives. Production began in September 2017, with practical effects again a priority for the series' crew. The season features the parasitic Amahl Farouk / Shadow King, portrayed by Negahban, searching for his original body after being forced out of Haller's mind at the end of the first season. The season premiered in Los Angeles on April 2, 2018, before its FX debut on April 3. It ran for 11 episodes, concluding on June 12. The series was renewed for a third and final season on June 1.

In January 2017, Hawley said he was open to continuing the story past the first season, but didn't want the audience to get to the end of the first run and have "no resolution of any kind at the end of it." Star Dan Stevens said, "I know for a fact that there are more issues that David has to deal with than the one that we really address in the first season." FX renewed Legion for a second season on March 15, 2017. At the end of that month, Hawley explained that he planned for the season to have ten episodes, and to focus more on the series' other characters in addition to David Haller. He added, "I do tend to think that that's important, that even though the show isn't an anthology like Fargo, each season has a self-contained-ness to it, an identity to it. But I think it's a little too early to talk about what that identity might be." The season order was later expanded to eleven episodes, as announced by FX in May. Writing Hawley noted that the first season was about Haller's internal struggle against the Shadow King, and that the latter's transference to the character Oliver Bird at the end of the season signified a change to an external struggle for Haller that this season would explore. Hawley wanted to avoid having a villain-of-the-year structure, with the second season introducing a new antagonist, instead wanting to continue the story surrounding the Shadow King from his introduction in the first
