Dan Stevens, Aubrey Plaza and Jean Smart have joined the cast of FX’s “Legion,” TheWrap has learned.
The actors join the previously cast Rachel Keller in the pilot from “Fargo’s” Noah Hawley.
Stevens will play David Haller, who has struggled with mental illness since he was a teenager. 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.
In the comics, Haller is a mutant and the son of Professor Charles Xavier, leader of the X-Men.
Plaza, who previously starred on NBC’s “Parks and Recreation” will play David’s friend Lenny. Smart, who previously worked with Hawley on “Fargo,” will play a therapist named Melanie.
Hawley will write the pilot and serve as an executive producer along with Lauren Shuler Donner, Bryan Singer, Simon Kinberg, Jeph Loeb, Jim Chory and John Cameron.
