  ==== ''Bloodmoon'' ====
  On June 8, 2018, HBO commissioned a pilot to a ''Game of Thrones'' prequel series from Goldman as showrunner and Martin as co-creator. The prequel was to take place in the Age of Heroes, a period that begins roughly 10,000 years before the events of ''Game of Thrones''. Notable events of that period include the foundation of powerful Houses, the Long Night when the White Walkers first descended upon Westeros, and the Andal Invasion when the Andals invaded from Essos and conquered most of Westeros. Martin suggested ''The Long Night'' as a title for the series. On May 13, 2019, it was reported that the show had already begun filming in Belfast, under the working title ''Bloodmoon''. S. J. Clarkson was announced to direct and executive produce the pilot, while Naomi Watts was cast as the female lead playing "a charismatic socialite hiding a dark secret." Other series regulars were to include: Josh Whitehouse, Toby Regbo, Ivanno Jeremiah, Georgie Henley, Naomi Ackie, Denise Gough, Jamie Campbell Bower, Sheila Atim, Alex Sharp, Miranda Richardson, Marquis Rodriguez, John Simm, Richard McCabe, John Heffernan, and Dixie Egerickx. In September 2019, Martin claimed the pilot was in post-production but in October 2019, it was announced that HBO had decided to not move forward with Goldman's prequel series.
