As Netflix’s The Crown has well and truly proven, there’s a huge appetite for well written televised dramas about the Royal Family.

So it makes sense that there’s one in the works which will feature public favourite Kate Middleton.

Mike Bartlett’s Olivier Award-winning play, King Charles III, is being adapted into a one-off drama for BBC Two.

The story will follow our modern-day royal family, imagining how events will play out when Prince Charles ascends to the throne following the death of Queen Elizabeth II.

As such, it will feature his two sons, Prince William and Prince Harry – as well as his eldest son’s wife and university sweetheart, Kate.

And now it has been confirmed that Peaky Blinders star Charlotte Riley has been cast as the Duchess of Cambridge.

Speaking to the BBC about the role, she said: “It's such a unique project. To be both modern and rich in verse and to play someone who is real but yet totally re-imagined for this story is an exciting prospect for an actor.

“Kate Middleton is a really interesting woman, particularly within the context of this play, and it is a challenge I am really looking forward to.”

Tim Pigott-Smith, who starred in the original West End play, will be reprising his role as King Charles for the drama, while Oliver Chris will play William, Richard Goulding will take on the role of Harry, and Margot Leicester will appear as Camilla.

Bartlett has since confirmed that the production on the “contemporary royal tragedy” will begin shooting shortly.

However, for staunch royalists, be warned; this may not be the show for you. In it, we will witness King Charles refuse to sign a controversial bill into law – and the country around him will descend into absolute chaos.

“It is a drama about us, now, who we are, and the relevance of our monarchy,” explained Bartlett. “Television gives it an important democratic voice.”
