What to Know About the Game of Thrones Prequel

There’s been a lot of speculation about the prequel to Game of Thrones but here’s what’s known so far.

What’s it about? Taking place thousands of years before the events of Game of Thrones, the series chronicles the world’s descent from the golden Age of Heroes into its darkest hour. From the horrifying secrets of Westeros’s history to the true origin of the White Walkers, the mysteries of the East to the Starks of legend, only one thing is for sure: It’s not the story we think we know.

Who will it star? New casting includes: Naomi Ackie (Lady Macbeth), Denise Gough (Monday), Jamie Campbell Bower (Sweeney Todd: The Demon Barber of Fleet Street, Fantastic Beasts: The Crimes of Grindelwald), Sheila Atim (Harlots), Ivanno Jeremiah (Humans), Georgie Henley (The Chronicles of Narnia films), Alex Sharp (How to Talk to Girls at Parties) and Toby Regbo (The Last Kingdom, Fantastic Beasts: The Crimes of Grindelwald).

These actors join Oscar-nominee Naomi Watts (21 Grams), who headlines as a charismatic socialite hiding a dark secret, and Josh Whitehouse (Poldark).

Who is behind it? Jane Goldman and GoT author George R.R. Martin are the creators of this new series, with Goldman serving as the showrunner. Both will executive produce, alongside SJ Clarkson (The Defenders, Jessica Jones, HBO’s Succession and the upcoming Star Trek installment), who will also be directing the pilot episode; James Farrell; Jim Danger Gray; Vince Gerardis; Daniel Zelman and co-executive producer Chris Symes. Martin was also an executive producer on Game of Thrones and contributed to several episode scripts.
