Royal Shakespeare Company Unveils First Cast Portrait for Game of Thrones: The Mad King

Nine actors standing in simple, unadorned clothing—no dragons, no wildfire, no CGI effects. That is how the Royal Shakespeare Company chose to reveal the cast of Game of Thrones: The Mad King, offering fantasy fans their first look at the generation whose fatal choices ignited Robert’s Rebellion.

The Story at a Glance

The Royal Shakespeare Company (RSC) has released the complete cast list and first official portrait for its ambitious stage adaptation, George R. R. Martin’s Game of Thrones: The Mad King. Previews officially launched at the Royal Shakespeare Theatre in Stratford-upon-Avon, England, with an official press opening night set for Saturday, Aug. 8, 2026. The world premiere production is slated to run through Saturday, Sept. 5, 2026.

Adapted by Duncan Macmillan and directed by Dominic Cooke, the four-hour epic serves as a direct stage prequel to Martin’s A Song of Ice and Fire novels. Co-produced alongside HBO and Warner Bros. Theatre Ventures, the play lands precisely on the 30th anniversary of the publication of the original 1996 novel, A Game of Thrones.

How the Story Developed

For decades, readers and television viewers knew King Aerys II Targaryen only as a terrifying piece of background lore—a tyrannical monarch remembered through the traumatized memories of those who survived his reign. Now, actor Michael Shaeffer brings the Mad King to life on stage, stepping out of the shadows to anchor a tragic historical chapter.

The play centers on the fateful Tourney at Harrenhal during the final years before the main story begins. Rather than presenting a simple tale of abduction and civil war, the production reveals a web of political conspiracies. Prince Rhaegar Targaryen (played by Noah Ritter) and Princess Elia Martell (Elizabeth Ayodele) actively orchestrate the tournament to build a coalition aimed at removing the unstable Aerys from the Iron Throne. However, Rhaegar’s sudden choice to crown Lyanna Stark (Harmony Rose-Bremner) as the Queen of Love and Beauty publicly shatters the political strategy, setting off a chain reaction that engulfs the Seven Kingdoms.

Key People and Details

The newly released ensemble portrait reads like a roster of Westerosi legends. From left to right, the image features Tanisha Spring as Ashara Dayne, Elizabeth Ayodele as Princess Elia Martell, Mariah Gale as Queen Rhaella Targaryen, Callum Woodhouse as Lord Robert Baratheon, Michael Shaeffer as King Aerys II Targaryen, Harmony Rose-Bremner as Lyanna Stark, Luke Brady as Brandon Stark, Noah Ritter as Prince Rhaegar Targaryen, and Michael Abubakar as Eddard Stark.

Beyond the core central cast, the broader 32-actor company includes Maxim Ays as Ser Jaime Lannister and Daisy Franks as Cersei Lannister. The ambitious production heavily incorporates puppetry designed by Nick Barnes and Finn Caldwell (Lume) to bring scale, movement, and creature elements onto the stage.

Reaction and Response

The road to opening night saw brief technical turbulence when the RSC was forced to cancel its initial week of preview performances in late July to fine-tune technical cues and give the creative team extra preparation time. Despite initial frustration from fans who had traveled to Stratford-upon-Avon, previews resumed on July 28 to a passionate standing ovation from the audience.

Early reviews from preview attendees highlight the show's intense theatrical energy and high production values, comparing the experience to binge-watching an HBO series live on stage. Shaeffer’s portrayal of King Aerys II has drawn particular early praise for delivering a menacing, grounded performance.

What to Watch

With the entire summer run at the Royal Shakespeare Theatre completely sold out, industry observers are closely monitoring whether the show will transfer to London’s West End or move across the Atlantic to Broadway. Because the production is staged in the round, a Broadway transfer would require either significant stage reconfigurations or a specialized venue, but the heavy involvement of Warner Bros. Theatre Ventures suggests long-term international plans for the show.
