It's official NBC will not pick up Constantine, it was also shopped around to other networks to no success.

I blame myself for this.  I watched binge watched Constantine after it was over and I really enjoyed the show and really hoped that somebody (Netflix) would pick it up.  If only I had watched this as it aired and contributed to the ratings or told more people to watch this…maybe…just maybe…

“Constantine’s” battle for survival has come to an end, as announced by Executive Producer Daniel Cerone in a message to fans via Twitter and TwitLonger.

“The cast and writers of Constantine are being released from their contracts,” Cerone said in his message. “The studio tried to find a new home for the show, for which we’re forever grateful, but those efforts didn’t pan out. I’m sorry, I wasn’t provided any information on the attempts to sell the show elsewhere. All I can report is that the show is over.”

Cerone also discussed the passion of the writers involved and concluded by thanking the dedicated fans and expressing his regret over not being able to deliver them more.

“To leave such a significant, dedicated and active fan base on the table — that’s the real sadness. You all deserve many years of the series we set out to make, and we’re disappointed that we couldn’t deliver that to you. The good news is that Constantine will live on for years in many more forms. But our time as caretakers has ended.”

Developed by Cerone and David S. Goyer for NBC, “Constantine” starred Matt Ryan as the titular hero and aired for 13 episodes. NBC decided not to renew the series for a second season, which promoted Warner Bros. Television to shop the series around to other networks.
