FX's X-Men spin-off Legion has hired actor Jeremie Harris to play a character named Ptonomy, according to The Hollywood Reporter. Harris is described a series regular by the Hollywood trade, but little is known about this apparently new character. THR describes Ptonomy as "an outsider by nature, stand-offish and sardonic who is a former child prodigy who feels trapped in the past."
Jeremie Harris has been seen in episodes of CBS's Blue Bloods and Person of Interest, and also appeared in HBO's Bessie. The recent Julliard grad is also appearing in Baz Luhrmann's upcoming Netflix series The Get Down.
Dan Stevens has previously been cast in the title role of FX's Legion, and the pilot is set to begin production in March.
