Welsh actor Matt Ryan (Assassin’s Creed:  Black Flag) is finalizing a deal to play the lead in NBC’s drama pilot Constantine, from Warner Bros TV. Based on the characters in DC Comics’ John Constantine stories, the project centers on John Constantine (Ryan), an enigmatic and irreverent con man-turned-reluctant supernatural detective who is thrust into the role of defending us against dark forces from beyond. John Constantine is described as a working-lass Londoner with rakish good looks, scruffy blond hair, deadpan humor, and signature trench coat, who has been studying the dark arts since he was a teenager. When the daughter of a late friend is targeted by demons, Constantine steps in to save her. The project was written by The Mentalist executive producer Daniel Cerone andDavid S. Goyer, the go-to writer for Warner Bros’ feature DC adaptations who has co-penned The Dark Knight, The Dark Knight Rises, Batman Begins, Man Of Steel and the upcoming Batman vs. Superman.
