Game Of Thrones: HBO Looks Beyond Season 8

When the last drop — or gallon — of blood is shed and an exultant victor has ascended to the Iron Throne, viewers may be split over how HBO’s fantasy saga ended but they’ll be joined in deprivation.

“What do you do without ‘Game of Thrones?’” will be the lament heard after the May 19 finale, said media analyst Larry Gerbrandt. The question is even more critical to the pay-cable channel, which soared on dragon’s wings with its hugely popular, eight-season adaptation of George R.R. Martin’s novels.

Keeping subscribers on board means more than another hit, even one as globally dazzling as “Game of Thrones” proved to be. But it’s where HBO can start to protect its brand and position, observers say, an effort both demanded and compounded by an increasingly congested small-screen landscape and the expectations of the channel’s corporate owner since 2016, AT&T.

“I think they need a prestige show on this level to remain HBO,” Bill Carter, a media analyst for CNN and former reporter for The New York Times. But “more than ever, it’s really hard to find a hit show and to break through in this marketplace.”

The channel is well into the hunt for a worthy successor, with one possibility an untitled prequel to “Game of Thrones” created by Martin and Jane Goldman and starring Naomi Watts. Set to begin shooting a pilot in June, it’s among several potential “Thrones” spinoffs being weighed, with discussions at HBO about “how many is too many,” said programming chief Casey Bloys.

“We have high hopes” for the pilot, he said. “But I want to be clear, nobody is going into this thinking that we’re going to do a prequel and all of a sudden everybody who automatically watched ‘Game of Thrones’ is going to watch this. ... It’ll have a different feel and different rhythm. We’re not trying to do the same show again.”
