“Hannibal” won’t go on at Netflix or Amazon, who have both passed on picking up new episodes of the canceled NBC drama, according to showrunner Bryan Funner.

“I’M SORRY TO REPORT @amazon AND @netflix HAVE PASSED ON #HANNIBAL S4,” he answered a fan on Twitter. “BUT WE’RE STILL INVESTIGATING POSSIBILITIES.”

The series, which stars Mads Mikkelsen as iconic cannibal Hannibal Lecter, has been a critical darling, though never a ratings hit. Hugh Dancy stars as FBI serial killer profiler Will Graham, and Laurence Fishburne appears as Jack Crawford, the agent-in-charge of the FBI’s Behavioral Science Unit in Quantico, Virginia.

In announcing the cancellation, NBC praised the series.

“We have been tremendously proud of ‘Hannibal’ over its three seasons. Bryan and his team of writers and producers, as well as our incredible actors, have brought a visual palette of storytelling that has been second to none in all of television — broadcast or cable,” the network said in a statement. “We thank Gaumont [International Television] and everyone involved in the show for their tireless efforts that have made ‘Hannibal’ an incredible experience for audiences around the world.”

For a recent airing during its third season, “Hannibal” drew an anemic 0.5 rating/2 share in the 18-49 demographic most important to advertisers, tying the previous week’s series low.

Executive producers on the series include Fuller, Martha De Laurentiis, Steve Lightfoot, Katie O’Connell Marsh, Elisa Todd Ellis, Christophe Riandee and Sidonie Dumas.

For his part, Fuller is emotionally prepared for the end of the show, as he goes into each season as if it’s the last.

“The first season, if we had ended with Will Graham taking the fall for Hannibal’s crime, that would have been a really bold finale for the series,” he told TheWrap. “Same with the second season, if we had left with Hannibal Lecter walking out the door after leaving everyone for dead, that would have been a bold ending to the series. The Season 3 finale is no different.”

“Hannibal” airs Thursdays at 10 p.m. ET on NBC.
