Production

On 18 February 2026, it was announced that the play would be presented by the Royal Shakespeare Company, with its world premiere at the Royal Shakespeare Theatre in Stratford-upon-Avon, directed by Dominic Cooke. Full casting was announced on 29 May 2026.[1]

Previews were scheduled to begin on 20 July 2026, however the first weeks previews were cancelled,[2] one with just a few hours notice.[3] The opening night is scheduled for 8 August, running until 5 September.[4][5][6]

The play is set 10 years before A Game of Thrones,[7] amidst a tournament at Harrenhal. Members of the inner circle of the titular "Mad King", Aerys II, plot against him, as fears grow about his accelerating ruthlessness.[8]
