It is a rare thing when a TV show feels like a warm blanket. Most modern dramas are about high-stakes murder or corporate backstabbing, but the all creatures great and small cast has managed to do something much harder: they’ve made us care about a cow with a cold. Honestly, the chemistry in the Skeldale House kitchen is the only reason the show works. If you didn’t believe in the friendship between James, Siegfried, and Tristan, the whole thing would just be a dry documentary about 1930s veterinary medicine.
Nicholas Ralph, who plays James Herriot, wasn't a household name when he got the part. That was a choice. Producers wanted someone who felt like an outsider entering the Dales for the first time. It worked. Ralph’s earnestness is the anchor. But let’s be real—Samuel West’s portrayal of Siegfried Farnon is what gives the show its bite. He’s chaotic. He’s brilliant. He’s also incredibly frustrating. That’s the magic of the ensemble. They aren't just actors hitting marks; they've built a rhythmic, messy family dynamic that mirrors the real-life memoirs of Alf Wight.
The Core Players of Skeldale House
You’ve got to start with Nicholas Ralph. This was his television debut. Can you imagine the pressure? He had to step into the boots of a legendary figure in British literature while following in the footsteps of Christopher Timothy from the original 1970s series. Ralph spent time on real farms, learning how to handle cattle and sheep, because the show refuses to use CGI for the animals whenever possible. If James looks like he’s actually worried about a horse, it’s usually because Nicholas Ralph is actually standing behind a very large, very unpredictable horse.
Then there is Samuel West. He plays Siegfried Farnon with a sort of frantic, eccentric energy that hides a deeply wounded heart. West is acting royalty—his parents are Timothy West and Prunella Scales—and he brings that pedigree to the role. He’s the boss, the mentor, and the surrogate father.
And then we have Tristan.
Callum Woodhouse brings a much-needed levity to the all creatures great and small cast. Tristan is the younger brother who can’t quite get his act together, the one who would rather be at the pub than checking on a pig. The dynamic between West and Woodhouse is where the show finds its humor. It’s that classic "older brother who cares too much" versus "younger brother who acts like he doesn't care at all." When Woodhouse’s character left for the war effort in later seasons, the house felt empty. It changed the entire gravity of the show.

Mrs. Hall and Helen: The Emotional Glue
Anna Madeley as Mrs. Hall is the person everyone actually wants to be. She is the housekeeper, sure, but she’s also the CEO of Skeldale House. Without her, the men would basically starve or kill each other. Madeley plays her with a quiet, watchful dignity. She doesn't have to shout to be the most powerful person in the room. Her slow-burn storyline—dealing with her estranged son and her burgeoning feelings for Gerald—is some of the most nuanced writing on television right now.
Rachel Shenton plays Helen Alderson. Now, if you’re a fan of the books, you know Helen is a pillar of the community. Shenton, who actually won an Oscar for a short film she wrote called The Silent Child, brings a grit to Helen. She isn't just a love interest for James. She’s a farmer. She’s a woman who lost her mother young and had to help run a struggling farm while raising her sister. When James and Helen finally got married, it didn't feel like a "happily ever after" trope. It felt like two hardworking people deciding to face a very difficult world together.
Supporting Characters That Make the Dales Real
The world of Yorkshire isn't just the main house. The all creatures great and small cast expands into the hills.
- Mrs. Pumphrey: Originally played by the legendary Diana Rigg. After her passing, Patricia Hodge stepped into the role of the eccentric, wealthy owner of Tricki Woo. It was a tough transition, but Hodge made the character her own without losing that "over-the-top" devotion to her Pekingese.
- Richard Carmody: Played by Hamish Blake. He’s the new blood. He’s brilliant, socially awkward, and serves as a foil to the more "instinctual" James.
- The Animals: It sounds cheesy, but the animals are cast as carefully as the humans. The production uses a dedicated team of animal handlers to ensure the "actors" are comfortable. Tricki Woo, in particular, is a scene-stealer who probably has more demands than the human lead.
Why This Cast Works Better Than the Original
Look, the 1978 version is a classic. Robert Hardy was an icon as Siegfried. But the modern all creatures great and small cast benefits from a shift in tone. The original was a bit more "jolly." The new version, while still cozy, isn't afraid of the dark. It deals with the looming shadow of World War II. It deals with poverty. It deals with the fact that sometimes, despite the vet's best efforts, the animal dies.
The actors have to carry that weight. When Nicholas Ralph has to tell a farmer that his only source of income has to be put down, you see the toll it takes on his face. That’s the difference. The chemistry isn't just about the laughs; it’s about the shared burden of a very difficult profession in a very difficult time.

Behind the Scenes: Authenticity Matters
The cast doesn't just show up and say lines. They go through "Vet Boot Camp."
Nicholas Ralph has spoken at length about learning how to "palpate" a cow. It’s not glamorous. It’s messy. It’s cold. They film in the Yorkshire Dales, often in the pouring rain or biting wind. That physical discomfort adds a layer of reality to their performances. You don't have to act "cold" when you're standing on a hill in Grassington in November. You just are cold.
The relationship between the actors off-screen seems to mirror the on-screen bonds. Samuel West often shares photos of the cast on social media, showing them huddling around heaters between takes or sharing a meal. That genuine affection translates. You can't fake the look Mrs. Hall gives Tristan when he's being an idiot—that's a look of real, exasperated love.
The Evolution of the Characters
As the show progresses into the war years, the all creatures great and small cast has had to pivot. James is no longer the wide-eyed boy from Glasgow. He’s a husband and a father-figure. Helen has moved from the family farm to Skeldale, adjusting to life as a "vet's wife" while maintaining her independence.
This evolution is why the show stays fresh. It doesn't reset every episode. If a character makes a mistake in Season 2, they carry the consequences into Season 4. Siegfried’s guilt over his service in World War I is a recurring theme that Samuel West plays with incredible subtlety. He isn't just "grumpy"; he's a man who has seen the world break and is trying to keep his small corner of it together.

What Most People Miss About the Casting
The casting of the local farmers is just as vital. These aren't "Hollywood" versions of peasants. The production often uses actors who have a rugged, weathered look that fits the Dales. It grounds the show. If the "clients" of the vet surgery didn't look like they spent 14 hours a day in the mud, the stakes wouldn't feel as high.
The show also handles the departure of actors with grace. When Diana Rigg passed, the show didn't just recast her with a lookalike. They brought in Patricia Hodge, who changed the energy of the character while keeping the spirit of Mrs. Pumphrey alive. It was a masterclass in handling a transition that could have easily derailed the show's momentum.
Actionable Insights for Fans and Aspiring Actors
If you're looking to dive deeper into the world of the all creatures great and small cast, there are a few things you should do to really appreciate the craft:
- Watch the "Making Of" Specials: PBS and Channel 5 often release behind-the-scenes footage. Watch how Nicholas Ralph interacts with the animal handlers. It changes how you view the "medical" scenes.
- Read the Memoirs: If you haven't read If Only They Could Talk by James Herriot (Alf Wight), do it now. You will see exactly which personality traits Samuel West and Nicholas Ralph "stole" from the real-life inspirations.
- Follow the Cast on Social Media: Samuel West in particular is a treasure trove of information about the filming locations and the historical context of the show.
- Visit Grassington: If you’re ever in the UK, go to the village where they film. Seeing the physical scale of the "surgery" helps you understand the intimacy the cast has to maintain in such a small space.
The success of the show isn't just about the beautiful scenery or the cute dogs. It’s about a group of actors who decided to treat a "cozy" drama with the same intensity and respect as a Shakespearean play. They don't wink at the camera. They don't act like they're in a period piece. They just act like people trying to get through the day, one calf at a time. That is why we keep tuning in.
Next time you watch, pay attention to the silence. Notice how much Anna Madeley says without speaking a word. Notice the way Samuel West's posture changes when James challenges him. That’s the real work. That’s why this cast is the best in the business.
