Helena Bonham Carter has landed a royal storytelling role…

The 57-year-old part-Spanish English actress will narrate Charles III: The Coronation Year, a BBC documentary that explores King Charles III‘s first year on the throne.

Charles III: The Coronation Year will air next month, as viewers are taken behind the scenes via exclusive access to see the landmark moments of the king and his wife, Queen Camilla’s, first year since the death of Queen Elizabeth II.

Filmed as Buckingham Palace prepared for, delivered, and celebrated the first Coronation in 70 years in May, and in the months that followed, the documentary features contributions from members of the Royal Family and key players in The King and Queen’s Household.

“It’s a real privilege to be given such extraordinary behind the scenes access to the first year of King Charles’ reign,” said Kate Phillips, BBC Director of Unscripted. “It is a remarkable time in history and this documentary will offer a unique insight into King Charles and Queen Camilla, and the preparation and planning leading to their coronation – a momentous ceremony watched by millions around the world.”

Oxford Films is producing the 90-minute documentary, which will air next month. EP for Oxford Films is Nicolas Kent and commissioning editor for the BBC is Simon Young. It’s directed by Ashley Gething, produced by Faye Hamilton and the writer and co-producer is Robert Hardman.

Bonham Carter played Princess Margaret in Seasons 3 and 4 of The Crown.
