George R. R. Martin has confirmed that Game of Thrones: The Mad King will move to London following its successful debut in Stratford-upon-Avon. The stage adaptation explores the events leading up to Robert’s Rebellion, offering fans a deep dive into the franchise’s backstory.

Game of Thrones: The Mad King, adapted by Duncan Macmillan and directed by Dominic Cooke, will transfer to London after completing its sold-out, five-star run at the Royal Shakespeare Theatre tomorrow, 5 September. Set decades before the events of Martin’s iconic fantasy series, the play begins with a crucial tourney at the ruins of Harrenhal.

The world premiere has attracted glowing notices, including a strong response from WhatsOnStage, reflecting its warm reception from audiences and critics alike. Michael Shaeffer stars in the production, bringing to life characters from a pivotal chapter in the Game of Thrones mythology.

Martin expressed his enthusiasm about the transfer, stating he “had an absolutely splendid time in Stratford upon Avon for the premier” and is thrilled the production will reach a wider audience in London. He called it “an exhilarating journey” into the story of Robert’s Rebellion.

Adapted from Martin’s vast lore, the play provides a rare theatrical exploration of the events that shaped the political landscape of Westeros years before the television series. The adaptation’s focus on the tourney at Harrenhal sets the stage for the conflict that ignited the rebellion.

The move to London marks a significant moment for the production, following its critical and commercial success in Stratford. Details on the London venue and run dates are yet to be confirmed.
