Actor John Thomson will finally indulge his secret desire to be part of a BBC costume drama as he begins filming a new adaptation of Wilkie Collins' classic detective story, The Moonstone.
The Cold Feet actor will play Sergeant Cuff, while Miranda actress Sarah Hadland stars as the pious Miss Clack in the five-part joint venture from the BBC and Miranda Hart and David Walliams' production company King Bert.
Described by TS Eliot as "the first and greatest of English detective novels", The Moonstone sees charismatic adventurer Franklin Blake embark on a quest to solve the disappearance of the priceless Moonstone diamond and to win the hand of its owner, heiress Rachel Verinder.
John said: "The Moonstone is a classic novel, and this has all the makings of classic TV.
"I've worked on a wonderful variety of projects over the years, but have secretly always wanted to be part of a big BBC One costume drama. The Moonstone is exactly that and I'm incredibly excited to be in it."
Sarah said she was thrilled to take on the role of the "interfering, manipulative little busybody", as filming began in Yorkshire.
"I am so excited to be playing the fantastically named and appallingly behaved Miss Drusilla Clack," she said.
Rising theatre stars Joshua Silver, who appeared in Photograph 51 alongside Nicole Kidman, and Terenia Edwards will make their television debuts as Franklin and Rachel in the adaptation from Rachel Flowerday (Father Brown) and Sasha Hails (Versailles).
Other cast members include Sophie Ward as Lady Verinder, Stewart Clarke as Godfrey Ablewhite, Leo Wringer as Betteredge, and David Calder as Mr Bruff.
It was previously adapted by the BBC nearly 20 years ago, with Greg Wise and Keeley Hawes playing the central couple.
The Moonstone will air later this year across five consecutive afternoons as part of the BBC's #LoveToRead campaign.
