CEO Casey Bloys, also HBO's executive, who is enjoying the success of 'Succession' at award ceremonies, shared significant insights in a recent interview with The Wrap with regards to the upcoming 'Game of Thrones' spin-off series titled, 'A Knight of the Seven Kingdoms: The Hedge Knight.'

A Knight of the Seven Kingdoms: The Hedge Knight' will be based on three novels from the 'Tales Of Dunk and Egg' series, including 1998's 'The Hedge Knight,' 2003's 'The Sworn Sword,' and 2010's 'The Mystery Knight.' The timeline of the series will be set a century before the happenings of 'Game Of Thrones' and decades after 'House Of The Dragon'.

Casey Bloys addressed reports which are stating that there are several 'Game of Thrones' spin-offs in the development process. He clarified that while those projects are still in progress, the only ones that have officially been confirmed and approved 'House of the Dragon 2' and 'The Hedge Knight.' Additionally, he stated that there are many other projects lined up but as of now, there are no significant updates to report on them.

Bloys has confirmed that filming is set to begin this year. While the production of the series was supposed to begin earlier, the makers are still in the process of casting and writing. There has been no release date announced yet. However, it's anticipated that the show will run for three seasons, based on each of the three books. It's expected to introduce new plots and characters, explore Westeros’ history full of politics, knights, dragons, and much more. 

But, official announcements regarding these are highly-awaited.
