Peaky Blinders alum Charlotte Riley is set to play Kate Middleton in BBC/Masterpiece co-production, King Charles III. Adapted by Mike Bartlett (Doctor Foster) from his own Olivier Award-winning and Tony-nominated stage play, the future-history story is produced by Drama Republic. Shooting begins this month on the 90-minute drama in and around Leeds for air in 2017. BBC Two carries it in the UK.

Written in blank verse, the one-off telefilm is an imagining of Prince Charles’ accession to the throne following the Queen’s death. When he refuses to sign a controversial bill into law, political chaos ensues. As Charles wrestles with his own identity, the drama explores the implications for him, his family and his subjects.

Tim Pigott-Smith returns to the title role of Charles, with Oliver Chris as William, Richard Goulding as Harry and Margot Leicester as Camilla. Also joining the cast are Priyanga Burford and Tamara Lawrance. The play originally ran at the Almeida Theatre. Rupert Goold is directing.

Executive producers are Greg Brenman and Roanna Benn for Drama Republic alongside Bartlett and Goold. Matthew Read is exec producer for the BBC and Rebecca Eaton for Masterpiece.
