'Game of Thrones' prequel play 'The Mad King' set for stage debut, explores young heroes of Westeros

The world of Westeros is expanding beyond television and books. A new stage production inspired by the Game of Thrones universe will premiere this summer at the Royal Shakespeare Theatre in Stratford-upon-Avon. Developed with creative input from George R. R. Martin, the play, titled The Mad King, revisits a turbulent chapter that predates the famous saga. By bringing the story to live theatre, the creators aim to present a fresh, intimate perspective on events that shaped the fate of the Seven Kingdoms.The drama unfolds at the legendary tournament of Harrenhal, years before the rebellion that changed Westeros forever. Audiences will encounter younger versions of well-known figures, including Ned Stark, Lyanna Stark, Jaime Lannister, and Robert Baratheon. Director Dominic Cooke describes them as “the characters that people really know, but much younger.”The production is designed to welcome both longtime followers and newcomers. In an interview with Deadline, Cooke explains, “One of our ambitions is to make a show that really works as well for people who don’t know the material as for those who do, and for every sort of shade in between,” adding, “So we’ve tried to create a contained piece as well as something that gives the fans all the extra bits of story that they don’t know.”The narrative places Lyanna Stark at its centre, portraying her as a decisive force behind future events. Playwright Duncan Macmillan notes that she is the “catalyst for so much that follows. In fact, I’d say that without Lyanna Stark, there is no Game of Thrones.”Cooke highlights her unconventional personality, saying, “She’s a really good swordsperson, so she doesn’t really fit the mould of how women at that time were supposed to behave.” He also describes her as “very intuitive and very smart, and she’s a live wire,” suggesting a character torn between duty and independence. The plot also includes a tragic romance, with Cooke remarking that “there’s a bit of a Romeo and Juliet-type story” linked to Prince Rhaegar.Casting focuses on portraying the characters in early adulthood, emphasising transformation and identity. Cooke says, “The main characters, apart from the king, are all in their 20s,” adding, “Part of the essence of this show is a story of growing up — rites of passage, people becoming who they are.”After its initial run, the production may transfer to London’s West End. Ticket sales are expected to begin in April, marking a major milestone as Westeros takes its first steps onto the theatrical stage.
