Queen Charlotte has made appearances in previous episodes on both seasons of “Bridgerton,” portrayed by actress Golda Rosheuval. She will be returning for the prequel show, likely in framing sequences. She’ll be joined by Adjoa Andoh, who plays Lady Agatha Danbury, and Ruth Gemmell, who plays the matriarch of the eponymous family, Lady Violet Bridgerton. Actor James Fleet has briefly guest-starred as King George III but does not seem to be reprising his role.

The new cast for the limited series will be led by India Amarteifio from the BBC’s “Line of Duty” police drama as the young Queen Charlotte. “Betrothed to the mysterious King of England against her will, Charlotte arrives in London only to realize she was not exactly what the royals were expecting,” reads Netflix’s synopsis of the character. She will be joined by relatively new face Corey Mylchreest as a young King George III. Mylchreest has an undisclosed role in the upcoming “Sandman” Netflix series.

Michelle Fairley (“Gangs of London”) will play Princess Augusta, the Dowager Princess and mother of King George. She’ll be attempting to keep her son in power as Britain changes around them. The final major character will be actress Arsema Thomas in her television debut, portraying a young Agatha Danbury. Fans will likely enjoy seeing Agatha rise and become the wonderfully-spicy Lady Danbury of the first two seasons of “Bridgerton”.

Hugh Saches reprises his role as Brimsley from the first two seasons, while Sam Clemmett (“Harry Potter and the Cursed Child — West End”) will play his younger counterpart. Richard Cunningham, fresh off “The Witcher,” will play Lord Bute, while Tunji Kasim (“Nancy Drew”) plays Adolphus, Rob Maloney (“Casualty”) plays the Royal Doctor, Cyril Nri (“Cucumber”) plays Lord Danbury.
