The 33-year-old star has landed the lead role in the eight-part series set in Marvel’s superhero universe, which is tipped to premiere not TV in early 2017.
Stevens will play David Haller, who is described as “a troubled young man who may be more than human”, Marvel said.
Stevens’ character “struggles with mental illness” and is 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,” they added.
X-Men director Bryan Singer is one of the executive producers on the show, which also stars Rachel Keller and Jean Smart from the television adaptation of Fargo and Aubrey Plaza from the comedy series Parks and Recreation.
The pilot – which has already been shot – was written by Fargo’s Noah Hawley, who also acts as another executive producer on the superhero series.
