The League alumna Katie Aselton is staying at FX with a co-starring role opposite Dan Stevens, Aubrey Plaza and Jean Smart in Legion, FX’s X-Men-universe pilot from Fargo creator Noah Hawley, Marvel TV and FX Prods.

Legion introduces the story of David Haller (Stevens), based on the Marvel comics character Legion, the son of X-Men founder Charles Xavier. Since he was a teenager, David has struggled with mental illness. A haunted man, David is getting tired of finding his way back to sanity and is about to give up when he meets the girl of his dreams, a fellow patient, and is confronted with the possibility that the voices he hears and the visions he sees might be real. Aselton will play the Type A Amy.

A busy Aselton will also concurrently appear in Jason Reitman’s Hulu series Casual and will next be seen in a recurring arc on HBO’s Togetherness. Her upcoming projects also include Lionsgate’s The Sea Of Trees for director Gus Van Sant and Warner Bros.’ Bastards opposite Owen Wilson, Ed Helms and J.K. Simmons.

Aselton is repped by ICM Partners, Untitled Entertainment and Sloane Offer.
