All Creatures Great and Small cast's off-screen style – including Samuel West, Rachel Shenton and more

Nicholas leads the cast as James Herriot, who often sports a classic 1940s slicked-back hair look and in season five, donned an RAF uniform after joining the war effort. 

In real life, James' appearance is much more casual, with his hair loose and pushed to the side. 

On what he likes most about playing James, Nicholas told PBS: "As an actor, what I love is, because it's based on real people, these characters are so three dimensional and the relationships are so strong, that it’s so much fun to play. 

"I get to play James in a multitude of scenarios, varying emotions – it's never just two-dimensional. He's never just 'the funny guy' or 'this guy.' It’s a wonderful scope and a range, so it's brilliant because it's such a challenge, and every day is different."

While Helen often opts for a practical wardrobe with denim overalls and a tweed blazer, her real-life counterpart likes to have fun with her fashion.

Unlike Helen, Rachel tends to wear her brunette locks loose over her shoulders while sporting a bold red lip. 

Revealing her favourite item of Helen's, Rachel said: "She wears dungarees with this cute little waist belt and headband. I'm like, 'Oh, that's so good.' So more dungarees for me, definitely."

Samuel's real-life look couldn't be more different from his on-screen character, who frequently sports tweed blazers with silk ties and lab coats. 

According to the show's costume designer, Samuel requested that Siegfried shouldn't look "too smart". Ros Little told PBS: "With Sam, when we first talked about this series, he said, 'I don't want to be too smart. I should be a bit shabby.' I said, 'Well, good. Because you would be,' because I’d spoken to people like older vets I'd made contact with."

While Mrs Hall often sports practical outfits for her housekeeping duties, Anna's real-life look is much more chic. 

The actress is frequently pictured wearing her locks loose while donning a stylish dress for red-carpet appearances. 

While viewers are used to seeing Callum wearing knitted jumpers and a slicked-back side-parting for his role in the show, in real life the actor lets his curls go free and is often pictured wearing stylish shirts and jackets.
