Watch: Legion Comic-Con Trailer
Marvel and FX debuted the first Legion trailer at Comic-Con.
"Legion" introduces the story of David Haller: Since he was a teenager, David has struggled with mental illness. 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.
Legion debuts in early 2017.
