George R.R. Martin, the author of the A Song of Ice and Fire book series that inspired the Game of Thrones TV show, has confirmed that the stage play The Mad King will move to London after its successful run at the Royal Shakespeare Company (RSC) in Stratford-upon-Avon. The play, which is set decades before the events of the Game of Thrones TV series, has now completed its performance at the RSC. Martin, who is credited as the creator of the play, collaborated with writer Duncan Macmillan and director Dominic Cooke, a five-time Olivier Award winner. In a post on his personal blog, Not a Blog, Martin shared his excitement about the upcoming London transfer. He wrote, "I had a splendid time in Stratford upon Avon for the premier of Duncan Macmillan and Dominic Cooke’s epic new stage production of Game of Thrones: The Mad King. And furthermore, I’m thrilled to announce that the production will be moving on to London to share the experience with a wider audience." While no specific dates or venues have been announced yet, fans are encouraged to visit the official website, www.gameofthronesonstage.com, for future updates. The play received positive critical reception during its initial run. In a four-star review, The Independent’s Alice Saville praised the production for delivering all the action and drama that Game of Thrones fans expect, including thrilling battles, dramatic deaths, and even dragons. She also noted that the play offers a deeper emotional experience, focusing on the human elements and the impact of loss on characters. The Game of Thrones TV series, which aired on HBO from 2011 to 2019, concluded after eight seasons. Since then, Martin has been involved in several related projects, including the released TV series House of the Dragon and A Knight of the Seven Kingdoms, as well as a forthcoming feature film titled Game of Thrones: Aegon's Conquest. The London transfer of The Mad King marks another step in expanding the Game of Thrones universe beyond the screen.
