Ryan’s John Constantine is a “master of the occult” who’s haunted by his past but finds himself suddenly called upon to defend humanity from the gathering forces of darkness.

Daniel Cerone (Dexter) penned the pilot and will executive-produce the project with David Goyer (Batman Begins) and Warner Bros. Television.

Ryan played Matt Rawson on the short-lived Criminal Minds spin-off. He’s also had roles on Torchwood, The Tudors and Vikings.
