King Charles III, adapted by Mike Bartlett from his Tony-nominated stage play, is part political thriller, part family drama, and a timely examination of contemporary Britain.

Prince Charles has waited his entire life to ascend to the British throne. But after the Queen's death, he immediately finds himself wrestling his conscience over a bill to sign into law. His hesitation detonates a constitutional and political crisis, and his family start to worry, with William and Kate becoming aware his actions may threaten their future. Meanwhile, an unhappy and frustrated Prince Harry starts a relationship with a 'commoner', just at the moment that the press is looking for a way to attack. With the future of the monarchy under threat, protests on the streets and his family in disarray, Charles must grapple with his own identity and purpose to decide whether, in the 21st century, the British crown still has any real power.

This adaptation retains the daring verse of the original text while fully realising on screen the ambitious scale and spectacle suggested by the play - from Westminster Abbey and Buckingham Palace to the restless streets of London. Tim Pigott-Smith (Downton Abbey, The Hour) reprises the role of Charles from the acclaimed West End and Broadway production, while Charlotte Riley (Close to the Enemy, Peaky Blinders) stars as Kate Middleton. Olivier award-winner Rupert Goold (The Hollow Crown, True Story) directs. It is produced by Drama Republic, the company behind Golden Globe, Bafta and RTS Award-winning dramas The Honourable Woman, Doctor Foster and An Inspector Calls.
