Prince Charles causes a tank to be stationed outside of Buckingham Palace

Is Prince Charles responsible for a tank that is outside of Buckingham Palace? Maybe not the Prince Charles, first-in-line to the throne we all know, but the future King Charles III in the BBC drama most certainly is.

King Charles III is described as a “future history” drama, which will take a look at life after Her Majesty passes away.

The new king becomes upset at a controversial bill, refusing to sign it causing a chaos, rioting in the streets and a tank outside of Buckingham Palace.

After waiting so long to be monarch, King Charles now struggles with is own identity, the show follows how this problem affects his family, his self and his country. The show is created by Mike Bartlett who adapted his Olivier-Award-winning stage play.

In the role of his daughter-in-law, Charlotte Riley has been cast to play the Duchess of Cambridge.

The 34-year-old actress, spoke to The Express about her newest role: “I’m really excited to come on board King Charles III, Mike Bartlett and Rupert Goold are two brilliant creatives.

“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 has been cast as King Charles, speaking of his role he said: “Performing King Charles in Mike Bartlett’s astonishing play in London and New York has been one of the high points of career,

“I am thrilled that we are to film it – it is a drama about us, now, who we are, and the relevance of our monarchy. Television gives it an important democratic voice.”

The cast rounds out with Richard Goulding as Prince Harry, Oliver Chris as Prince William, Margot Leicester as the Duchess of Cornwall and Adam James as Prime Minister Tristram Evans.

The BBC drama will start filming late this month.
