Directors of the show
Michael Cuesta, who helmed Homeland and Dexter, is slated to direct the series. Alongside Loren Yaconelli (Shameless, The Walking Dead: Dead City), he will executive produce and direct the first two episodes of the show.
Michael Cuesta, an American filmmaker and writer, is well-known for his film and television work. He is known for his strong storytelling and creative vision. He began with the award-winning film L.I.E. in 2001.
