Lucy Griffith (“True Blood”) is the female lead in NBC and Warner Bros. TV’s upcoming adaptation of DC Comics’ Constantine. She will star alongside Matt Ryan (“Criminal Minds: Suspect Behavior”), who plays the titular antihero—an ex-conman turned supernatural detective out to save humanity from demonic forces.

Griffith will play the daughter of Constantine’s dead friend who helps him fight evil after he rescues her from demons. Also along for the ride is Harold Perrineau (“LOST”) as Constantine’s guardian angel Manny. Neil Marshall (The Descent) is attached to direct the premiere episode.

Griffith is best known for playing Eric Northman’s vampire sister Nora on season five of HBO’s “True Blood,” and for her role as doomed Lady Marion of Leaford on the BBC program “Robin Hood.” She also starred on The CW’s short-lived tween zombie drama “The Awakening.”
