George RR Martin has signed a new contract with HBO ‘worth mideight figures’ and running for five years to develop several new television series. These appear to be in addition to five projects the Game of Thrones / Song of Ice and Fire author already has with the network and which include a Game of Thrones prequel called House of the Dragon which is due to start filming any time now for screening next year. Other projects already announced include a drama called 10,000 Ships, set a millennia before Game of Thrones; a show about Flea Bottom; an untitled House of the Dragon spin-off; an untitled animated series and a screen version adapting three novellas chronicling the adventures of Dunk and Egg.
On top of all this, The Guardian reports that Martin is developing a stage play which will serve as a sort of prequel to A Game of Thrones, exploring a key event which happened sixteen years before the beginning of the first novel.
