It was announced last week that NBC has officially ordered a pilot for "Constantine," based on the DC Comics/Vertigo character. Though we know the script for the series has been written by David S. Goyer (Batman Begins, Man of Steel) and Daniel Cerone ("The Mentalist"), it was still unclear how dark the series will be. In an interview with IGN, NBC chairman Robert Greenblatt spoke about the show's tone and what we can expect from the supernatural elements.
"I don't know the DC comic very well, but there is dark, interesting stuff in it, but it’s also got some witty banter. It's a fun tone, although the supernatural stuff is scary."
When asked if the "Constantine" series might at some point cross over with the other DC Comics-based series, including "Arrow" and "The Flash" at The CW and "Gotham" at Fox, Greenblatt replied: "Cross-network is really hard. It's hard enough to do it within your network. I think let us see how the pilot goes before we answer that question!"
Created by Alan Moore, 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.
