Harold Perrineau ("Lost"), Lucy Griffiths ("True Blood") and Charles Halford ("True Detective") have joined the cast of NBC's "Constantine," a TV series adaptation of the "Hellblazer" comics series.
Matt Ryan plays John Constantine, a supernatural detective who struggles with his faith as he is haunted by the sins of his past and is suddenly thrust into the role of defending humanity from the gathering forces of darkness.
Griffiths plays the female lead Liv, an offbeat young lady who can see the supernatural world around us and is marked for death by a powerful demon.
Perrineau is Manny, an authoritative angel assigned to watch over Constantine. Though only meant to observe, he will not hesitate to help save a life. Halford is Chas, Constantine's oldest friend and staunch companion.
Neil Marshall will direct the pilot, which will film in Atlanta.
