Holby City is a British medical drama television series that premiered on 12 January 1999 on BBC One. The series was created by Tony McHale and Mal Young as a spin-off from the established BBC medical drama Casualty.^[1] It is set in the same hospital as Casualty, Holby General, in the fictional city of Holby,^[2] and features occasional crossovers of characters and plots with both Casualty (in episodes broadcast as Casualty@Holby City^[3]) and the show's 2007 police procedural spin-off HolbyBlue.

Holby City follows the professional and personal lives of surgeons, nurses, other medical and ancillary staff and patients at Holby General. It features an ensemble cast of regular characters, and began with 11 main characters in its first series, all of whom have since left the show. New main characters have been both written in and out of the series since. In addition, Holby City features guest stars each week, as well as recurring guests that take part in story arcs that span a portion of a series. Occasionally, the recurring guest storylines will span multiple series. Many actors in the series have made prior, minor appearances as both patients and staff members in both Holby City and Casualty - in some instances crediting these former appearances for their later casting as main characters in Holby City.

In casting the first series of Holby City, Young selected actors who were already established names in the acting industry, primarily from a soap opera background. He cast Michael French as Nick Jordan, George Irving as Anton Meyer, Angela Griffin as Jasmine Hopkins, Lisa Faulkner as Victoria Merrick and Nicola Stephenson as Julie Bradford. Young explained: "Soap actors are the best actors. There's been so much snobbery before. The whole thing about typecasting was probably invented by actors who couldn't get other work. From day one I knew I wanted to put on screen people that viewers want to watch. There's no downside to that."^[4] This propensity for hiring established actors continued as the soap progressed, with later roles being awarded to comedian Adrian Edmondson, Patsy Kensit and veteran actor Robert Powell.^[5] When Jane Asher was cast in the recurring role of Lady Byrne in 2007, Inside Soap magazine asked series producer Diane Kyle whether the production team intentionally sought out "well-known-names", or whether roles simply went to the actor best-suited for the part. Kyle responded: "It's lovely when we have a new member of the cast come in and bring an audience with them. But we want the best actors, and the star names we cast are always the best - which is why we go for them."^[6]

Many cast members who play main characters have made previous appearances in Holby City and Casualty in minor roles. Amanda Mealing, who plays cardiothoracic consultant Connie Beauchamp, appeared as the mother of a paediatric patient in the show's fourth series.^[7] Luke Roberts, who plays registrar Joseph Byrne, appeared as the son of a medical professor in Holby City's seventh series,^[8] Rosie Marcel, who plays registrar Jac Naylor appeared in both Holby City and Casualty as a patient on three occasions.^[9] Stella Gonet, who plays CEO Jayne Grayson, had a minor role as an anaesthetist in Casualty, while Hari Dhillon, who plays general surgical consultant Michael Spence, previously appeared as a recurring anaesthetist in Holby City.^[10] In some instances, actors have stated that it was their guest appearances which led to their casting in more permanent roles. Roberts believes that his single scene in series seven was enough for him to be called in for the part of Joseph,^[11] explaining: "I hear it got the attention of the producers. Amanda Mealing put a good word in for me that day as well."^[12] Conversely, Dhillon dismissed his minor role as Dr Sunil Gupta as a part he took immediately after leaving drama school, unable to even recall the year of his appearance.^[10]

Jeremy Sheffield plays Alex Adams, a cardiothoracic registrar and a protege of Anton Meyer. He appears from series three, episode one until series five, episode 45. A romance with SHO Sam Kennedy almost ends his career, when Sam gets him drunk in an attempt to lure him into spending the night with her. Unaware he is over the speed limit, Alex causes the death of a young boy due to drink driving. He escapes a jail sentence, but departs for America when Meyer accepts a position overseas. He later returns and has a brief romance with Jess Griffin, as a result of which she becomes pregnant, but opts for an abortion.

Rebecca Grant plays nurse Daisha Anderson, who first appears in the episode "Twelve Hour Nightmare", series ten, episode 24.^[13] Daisha is described by the BBC as "a forthright and assertive Filipina with a highly tuned sense of right and wrong. She doesn't understand hierarchy or tact but is straightforward and honest and has a natural antenna when it comes to flirting."^[14] Holby City was Grant's first television role. She explained of her introductory storyline: "Some characters get a huge introduction, but mine has a 'flow' to it."^[15] Daisha's first appearance in Holby City explains that, although the character has been working at Holby City Hospital for some time in order to financially support her family in the Philippines, she has previously only worked on the Orthopedic ward - not one of the four wards the show focuses on.^[13] Daisha forms a close friendship with nursing consultant Mark Williams (Robert Powell). She flirts with Mark in order to win a transfer to Darwin ward,^[13] and moves in with him after breaking up with her boyfriend and being assaulted by her landlord, coming to rely on him yet further upon discovering herself to be pregnant.^[16] Mark also aids Daisha in becoming ambassador of the Byrne Foundation for cardiothoracic care,^[17] and promotes her to Sister of Keller ward, leading some to question the true nature of their relationship.^[18]

She is at the beginning of a new stage in her life, and it's quite an upturn for her, and she's just very interested in getting to know everyone and is excited at being part of a group."^[22] The BBC describe Rachel as: "warm and kind but perhaps a little too trusting. She's anxious to please. She loves nursing but her real passion is her boyfriend, Patrick."^[23] Antoine received just a thumbnail sketch of Rachel's background, but commented that: "I love it. Give me a bit of spare time and I'll tell you what my character did age four and a half - whether it's a lot or a little, it's all good."^[24] During Holby City's eleventh series, Rachel uncovers Daisha Anderson's post-natal depression and helps to support her, before being transferred to the hospital's geriatric ward. Executive producer Tony McHale commented on Rachel's transfer: "Although she is still working in the hospital, we are not likely to see her on our regular wards for some time."^[25] Rachel is of Afrocaribbean heritage.

Of Dan's relationship with Maddy, Wingfield explained: "There was a line in one of the last episodes, 'one of them seems perfect for you' and I always thought that summed it up. Dan and Maddy have always been incredibly close without becoming lovers, but it is obvious that they are great together, so when it happens it is effortless and joyous and has wonderful potential. But Dan's private demons prevent it from being allowed to live and grow. I always thought it might be great for him, if only he could have let it be."^[51] Similarly, Nadine Lewington who plays Maddy assessed: "Dan loved Maddy sincerely which is why he didn't want to risk hurting her any more than he already had. He was too messed up to be good for anyone and he knew it."^[52]

Wingfield describes Dan as "decisive, quick-thinking and pragmatic", explaining that "he doesn't allow emotion to control his choices".^[53] He says of his reception: "People really responded to the character.

A little bit of hanky panky is part of the human condition, after all!"^[133] Of his decision to transfer to Casualty, French explained: "The BBC came up with the idea [...] At first, I wasn't sure about him moving away from heart surgery, but we soon thrashed some ideas around and I realised it would work.

George Irving plays cardiothoracic consultant Anton Meyer from Holby City's first episode until series four, episode 46. Irving had considerable input in creating the character, who was initially envisioned by the series producers as an Iranian surgeon named Hussein. At Irving's suggestion, Meyer became Hungarian, an emigrant to Britain following the 1956 Hungarian Revolution. Little of the backstory created for Meyer was ever revealed on-screen, as part of a deliberate bid to present the character as enigmatic, allowing viewers to project their own imagination onto him.^[165] Meyer is a sarcastic, arrogant surgeon, with high expectations of his colleagues. His major storylines see him operate on his own sister, fear that he may have motor neuron disease, lose his spleen after being shot in a road rage incident, and ultimately depart from Holby for Michigan when the hospital Board make impositions on his autonomy.

From the Ukraine, Frieda is a sardonic goth. She's as cynical as she is honest. Happy to take the night shift to avoid the politics and people that make life too complicated. She won't indulge egos and her bedside manner leaves a lot to be desired, but beneath it all, she does have a real compassion and vulnerability. She's unlikely to forge friendships with ease but when she does it's likely to be one she'll fight tooth and nail for.

Executive producer Belinda Campbell stated that Rouass brought a "fresh new energy" to the series and that Sahira had been a "joy to create", commenting on the character: "While on the surface she appears to be cool and calm, underneath it all, she is kicking madly just to keep afloat.

Despite Kyle returning with a new partner, Isaac is jealous of Kyle's history with Dom and sees him as an "obstacle" and a "threat", which he needs to remove to isolate Dom and maintain control. Elliott stated that Isaac focuses on "competitiveness and one-upmanship".^[255] The story climaxes when Dom falls down the stairs during an argument with Isaac. Writers decided not to have Isaac pushing Dom and instead, focused on Dom's fear of Isaac, which causes him to step backwards and fall down the stairs. Elliott thought that in the scene, Isaac is portrayed as "threatening", "intimidating" and "menacing".^[255] Dom then reports Isaac's abuse and reveals the extensive off-screen abuse he has received from Isaac, resulting in his suspension. Elliott found it "powerful" to see one violent attack on-screen rather than multiple and thought that it highlighted how domestic abuse victims can hide their suffering.^[255]

Elliott reprised the role in 2019 and Isaac will return in episodes first broadcast in May 2019.^[256] His return was announced, via a show trailer advertising upcoming stories, on 6 March 2019.

The actor explained, "In order to reconstruct his life, Dom has to deconstruct it all first.
