'Masterpiece' Confirms 'All Creatures Great & Small' Season 4 New Cast

All Creatures Great & Small began filming Season 4 in March 2023, but spoilers about the new season have been held tightly under wraps. Viewers knew Season 3 ended with Tristan heading off to war and James chomping at the bit to join him. While most could guess from history how things would play out in the larger world in 1940, it remained a mystery how things would go at Skeldale House, how Seigfried and James would get on without Tristan, and how Helen might cope, should James be called up to also join the veterinary service at the front.

However, with Masterpiece's announcement of Season 4 details as filming continues in Yorkshire, we have a better idea of what's in store for the series's fourth installment and what new faces might be seen around the practice. The good news is that Seigfried will get help, as Neve McIntosh (Shetland) joins the cast as highly efficient bookkeeper Miss Harbottle. Also joining the series for Season 4: James Anthony-Rose (Slow Horses) as the studious undergraduate vet student Richard Carmody, who arrives at Skeldale to help cover during Tristan's absence.

Those who have watched the original All Creatures Great and Small's first season may remember Miss Harbottle, played by the late Australian actor Madge Ryan (A Clockwork Orange); she was the secretary who Seigfried hired in the early going and whom he drove to quit from his absolute refusal to cooperate in keeping the bills paid or the paperwork in order. As for Richard Carmoody, he was also introduced in Season 1 of the 1970s adaptation. Initially played by Christopher Brown (The Remains of the Day), the character appeared as one of Tristan's rivals and a victim of the younger Farnon's penchant for pranks.
