"Constantine" is officially dead.

Following its cancellation at NBC last month, fans hoped the series would be picked up by another network. With support from the cast and crew, fans launched a #SaveConstantine campaign hoping to save the show.

"Arrow" actor Stephen Ammell tweeted, "Hey TV Networks / Netflix and the like... If you pick up the show, I'll guest star. Can't wait. Constantine & Queen want to get [s--t] done. Let's make it happen."

Unfortunately, their efforts were unsuccessful.

Executive producer Daniel Cerone confirmed via Twitter that the studio's efforts to find "Constantine" another network home "did not pan out" as planned.

"I promised I'd share news when I had it - sadly, that news is not good," he said. "The cast and writers of Constantine are being released from their contracts. 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."

"Constantine" did get off to a rocky start on NBC with low ratings and middling reviews. NBC decided not to extend its 13-episode order and later cancelled the show after one season.

"Constantine," which premiered last October, followed John Constantine, a demon hunter struggling to reconcile his past sins while on a mission to stop demons and evil forces from breaking through the human world.

In his post, Cerone went on to thank "the dedicated cast that breathed these characters to life, led by Matt Ryan as the comic-made-flesh embodiment of John Constantine, to the exceptionality talented crew that put unreal images on screen, to the original Hellblazer writers and artists who gifted us a universe."

"To leave such a significant, dedicated and active fan base on the table - that's the real sadness," he wrote. "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. Thank you for letting us in."

"As a general principle, writers don't choose a writing career to achieve stardom. Whatever demons or insecurities drove them to find freedom of expression through written words generally keeps writers comfortably obscure behind their words. Nor do people choose writing as a means to financial freedom. I'd venture to guess that most who set out to write professionally never receive a paycheck for their hopeful scribbles or key strokes."
