MORE actors have been announced ahead of the launch of a new TV adaptation of All Creatures Great and Small.

Award-winning actress Dame Diana Rigg will play an indomitable dog-lover in the series based on the James Herriot books, which is set to air on Channel 5 this autumn.

Dame Diana, who played Olenna Tyrell in Game of Thrones, joins as Mrs Pumphrey, the eccentric owner of the overly indulged Pekingese Tricki Woo.

“James Herriot has a special place in the heart of the public and the commission of this iconic drama series, against the stunning backdrop of the Yorkshire Dales, is set to bring joy to a new army of TV viewers,” said Sebastian Cardwell, from Channel 5.

“The original books affectionately captured a unique slice of British life; in challenging times, we hope the charming and heart-warming stories of community and compassion will resonate with new audiences.”

Filming for the six-part series is currently in production and marks the 50th anniversary of the original publication by Thirsk vet Alf Wight.

The series originally ran on BBC One from 1978 to 1990.

Nicholas Ralph will make his television debut as the iconic vet who became renowned for his inspiring compassion, humour and love of life.

Samuel West (Mr Selfridge, On Chesil Beach) joins as Siegfried Farnon, the wonderfully eccentric veterinary surgeon and proprietor of Skeldale House who reluctantly hires the recently qualified Herriot into his rural practice.

Mrs Hall, the resident housekeeper and matriarch of Skeldale House will be played by Anna Madeley (The Child in Time, Patrick Melrose).

Siegfried’s errant and charismatic younger brother, Tristan, will be played by Callum Woodhouse (The Durrells). Rachel Shenton (Switched at Birth, White Gold) takes the role of Helen Alderson, an independent local farmer’s daughter who helps her father manage the family farm and care for her younger sister.

“The books of James Herriot have enchanted millions of readers worldwide for almost half a century,” said Jim Wight and Rosie Page, Alf Wight’s children.

“We are delighted that our father’s work will be brought to life once again for a new generation of viewers great and small.”
