Marshall is no stranger to supernatural stories having directed the cult hit Dog Soldiers, along with The Descent, Doomsday and Centurion, as well as two episodes of Starz's "Black Sails" and HBO's "Game of Thrones."
Created by Alan Moore, Steve Bissette and John Totleben, John Constantine, a roguish magician/detective/conman, first appeared during the author's run on "Swamp Thing" in 1985, receiving his own series, "Hellblazer," under DC's Vertigo imprint in 1988. That book ran for 300 issues before it was relaunched in DC's "New 52" continuity as "Constantine" with a younger take on the antihero. It's speculated that the latest incarnation of the character will serve as the building blocks for the TV series.
Keanu Reeves previously played the character on the big screen in Warner Bros.' 2005 release Constantine, which was directed by Francis Lawrence ("The Hunger Games" films).
