Casualty exclusive: Kellie Shirley on romance for Sophia and returning to EastEnders

“Casting director John Cannon (whose other credits include Silent Witness, Father Brown and Sister Boniface Mysteries) came to see me in Abigail’s Party at Park Theatre in London and afterwards told me about this part. I’ve known John since my time in EastEnders and it just fitted. My mum was a nurse, my granny was a nurse, and my mother-in-law is a nurse, so it felt like the stars were aligning!” 

“I’m really lucky to have people in my life that I can draw from, and Sophia is a mishmash. There are definitely elements of my mum. She came from an estate, started nursing college when she was 17 and worked her way up, and is in my blood! 

“I also know a real psychiatric liaison nurse, so I’ve asked her loads of questions, from medical diagnoses to how she wears her hair – always in a bun and never down! 

“I did a lot of research, because I wanted Sophia to feel rooted, real and like she belongs in Holby.”

“John explained that she was at the top of her game and completely bossing it. I’ve been acting for over 20 years and I rarely play characters that have a career; it tends to be single mums or people who don’t have jobs. It’s great to play someone who is down-to-earth and likeable, but also knows her stuff and is very good at it.” 

“It’s a very interesting story where Sophia and Dylan are treating a young man called Benji Watts (Gwion Glyn) and both their skill sets come together. They find out that they work alongside each other nicely — until Dylan puts his foot in it with some clangers and they go back to square one!”

“They spar a lot to begin with because his manner riles her — he really gets on her nerves because he’s so abrupt and rude with no filter! But then Sophia sees another, more vulnerable side to him. She starts to think differently and you see the relationship blossoming. Also, the fact that he’s at the top of his game and is a surgeon who’s really good at his job is sexy and an aphrodisiac for her!”

“It’s a roller-coaster! I was so nervous on my first day because I wanted to get it right. I’d only just had my baby, he was six months old, and I was sleep deprived (Kellie is mum to eight-year-old twins and welcomed her third child in March 2023). But it fed into the role because real nurses and doctors are knackered, so it felt perfect using that!”

“The first scene I filmed was with Charles Venn (who plays paramedic Jacob Masters and is a fellow ex-EastEnder) and he delivered a monologue of medical jargon so effortlessly, I was in awe and knew that was the level I had to be at.”

“Yes! I can’t deal with needles or blood. Even saying the word ‘blood’ makes me feel weak! Luckily, Sophia works in mental health, so I don’t have to deal with stuff like that. I really love the authenticity of Casualty. We’re working alongside NHS professionals to make high quality, well-researched drama that deals with massive subject matters, and there’s real care taken in making the show.” 

“Growing up I knew the hospital environment a little and, later, in between acting jobs I’ve done some nurse-y stuff, such as being a care assistant in nursing homes and working at King's College London and Lewisham Hospital on neuro wards with a company called InterAct, reading to people who’ve had brain traumas.”

“I find it difficult to watch myself, but my mum will, definitely! I think she’ll be proud of it. Travelling between London and Cardiff with my baby has been a mega operation but my mum and mum-in-law have been amazing. Sarah Seggari, who plays nurse Rida Amaan, and Anna Chell, who plays Jodie Whyte, have helped me out too, so it’s been a real community village effort.”

“Yes! I feel really lucky to be working alongside these quality actors and incredible human beings. I’ve also bonded with Charles. We’ve been swapping EastEnders stories and I’ve worked on his short film How to Navigate Being a Monster with him, Sarah, Anna, Milo Clarke (who plays paramedic Teddy Gowan) and Di Botcher (who plays paramedic boss Jan Jenning). It’s really good and very different to Casualty!”

“There’s a big spectrum of different issues from a cross section of society, from a young man dealing with a severe mental health problem to an older woman, which is really commendable.”

“All the time, and it blows my kids' minds because it was before them. The last time I was on the screen with EastEnders was 2012 and people are still like ‘Carly!’ I always think, ‘How do you know it's me with all the wrinkles on my face, like how can you tell?!’”

“Of course — there’s always unfinished business in Walford! I’d love to put on Carly’s overalls for a brief spat before running off again. I’m good friends with Matt D’Angelo (who plays Carly’s half-brother, Dean Wicks), Linda Henry (Carly’s mum, Shirley Carter) and Emma Barton (Honey Mitchell), and Danny Dyer (who played Mick Carter) stars in a drama podcast I’ve written called ROAR. I’m very grateful to EastEnders, it’s had a massive effect on my life.”
