According to The Hollywood Reporter, NBC has cancelled the superhero drama Heroes after four seasons.

After debuting to audiences averaging 14.3 million during its first season, viewing figures began to decline as a result of what many deemed to be a disappointing and drawn-out second series. Viewership only worsened during seasons three and four, with the latest series falling to a low of 3.9 million.

The creators and cast of the once highly acclaimed show were hopeful that NBC would bring back Heroes for one last 13-episode series to wrap things up. However, the network is currently in talks with the series creator, Tim Kring, about the possibility of producing a two-hour TV movie to give the show a sense of closure.

Greg Grunberg, who played telepathic cop Matt Parkman, is still optimistic about a potential Heroes TV movie. “I hope that we can work it out. I mean, I'm certainly willing to come back and I think everybody is. I've talked to everybody and everybody really wants to wrap this up."

"I think we were in a good creative place and getting back to a place where people were happy with the show again," he said. “So let's wrap it up and see where these characters go. And not kill them all off. Let's have some sort of… happy ending. I mean, that would be nice, wouldn't it?”
