Game of Thrones is arguably HBO's biggest series of all time, so it's no surprise the company is trying to capitalize off that success with several spin-offs. According to author George R.R. Martin, however, several of these spin-offs have been shelved due to the ongoing changes at Warner Bros. Discovery.

Game of Thrones aired from 2011 to 2019, but the landscape over at HBO was different then. HBO Max did not launch until 2020, and Warner Bros. was acquired by Discovery shortly after. The new CEO of Warner Bros. Discovery, David Zaslav, has since made several controversial calls, including the cancellation of several projects over at HBO Max.

In a recent blog post on his "Not a Blog," Martin wrote an update for fans. He stated that he was hard at work developing several projects (he also assured fans he was writing The Winds of Winter) over at HBO. "Some of those are moving faster than others, as is always the case with development," Martin wrote. "None have been greenlit yet, though we are hoping… maybe soon. A couple have been shelved, but I would not agree that they are dead. You can take something off the shelf as easily as you can put it on the shelf. All the changes at HBO Max have impacted us, certainly".

Game of Thrones, Daenerys Targaryen

Rumors had previously swirled that two Game of Thrones spin-offs were axed at HBO after they had been removed from the slates of their production websites. One of the series is reportedly a prequel focused on a character from House of the Dragon. The Sea Snake would star Corlys Velaryon (Steve Toussaint in House of the Dragon) as he traverses the world of Ice and Fire.

The other Game of Thrones project is supposedly set to cover a lesser-known piece of lore mentioned early on in House of the Dragon. Ten Thousand Ships would center on the legendary warrior Nymeria, who led her people away from the dragon lords of Valyria and into Dorne. Ten Thousand Ships and The Sea Snake may be the shelved projects, as both would take audiences far away from Westeros, which could be a risky prospect.

It is unknown if the Jon Snow spin-off is still in the works or has been shelved. That Game of Thrones spin-off has been mentioned by Kit Harington as recently as November, and though he remained tight-lipped, he hoped it would come to fruition. That project seems like the safest bet because it is directly connected to Game of Thrones and may allow the writers to redeem season 8 of the series, which was widely disliked.

Game of Thrones is now available on HBO Max.
