All Creatures Great and Small cast: Who stars in season 6?

All Creatures Great and Small returns to screens for season 6 – and it's all change as the war officially draws to a close.

"As victory in Europe is declared, there is the promise of peace at last, but James is wishing for a greater sense of peace at the surgery as he juggles vet work with a busy family life and an exceptionally challenging Siegfried," reads the synopsis.

Elsewhere, "Helen’s enjoying time with young Jimmy and Rosie but has big changes afoot at Heston to contend with", while "Tristan returns from several years at war and will have to re-adjust to life back home in Darrowby".

"Meanwhile, Mrs Hall works hard to bring everybody back together and restore harmony at the surgery," continues the logline.

Alongside the main cast, a number of new guest stars appear in the latest chapter.

Who is James Herriot? The iconic young Yorkshire vet, played by Christopher Timothy in the original 1970s television series. Working in rural Yorkshire in the 1930s and '40s, James struggles at first to adapt, but soon finds himself won over by both the community and animals he works with. At the beginning of season 5, James is away from his wife and son Jimmy, who was born in the Christmas special, at an RAF training base, but has since returned home after being ruled unfit to serve due to contracting a bacterial disease.

Rachel Shenton plays Helen Alderson

In season 1, she had a longstanding romance with landowner Hugh, but later broke things off to embark on a relationship with James.

Samuel West plays Siegfried Farnon

Who is Siegfried Farnon? A wealthy and capricious veterinary surgeon who – reluctantly – hired the recently qualified James Herriot to become his assistant. Siegfried is also the proprietor of Skeldale House and its veterinary practice. He is a widower, and he also raised his younger brother Tristan after the death of their parents, who he loves dearly, but regularly locks horns with – however they have taken steps to bond more in recent seasons.

Callum Woodhouse plays Tristan Farnon

What have I seen Callum Woodhouse in before? Prior to All Creatures, he was best known for another period drama, ITV's The Durrells.

Anna Madeley plays Mrs Hall

Who is Mrs Hall? The housekeeper of Skeldale House. Mrs Hall is a force to be reckoned with – often putting her employer in his place – but she is kind and loving at heart, and usually knows what's best. She previously left an abusive relationship and has a grown-up son called Edward, who nearly died while serving in the military. Mrs Hall previously enjoyed a very sweet romance with a man called Gerald, but he left Darrowby to care for his sick sister.
