# Casualty@Holby City

Casualty@Holby City (styled as CASUAL$^+$Y @ HOLBY CI$^+$Y) is a series of special crossover episodes of BBC medical dramas Casualty and Holby City. While Casualty was launched on 6 September 1986, and its spin-off Holby City was first aired on 12 January 1999, the first full crossover episode between the two programmes was not broadcast until 26 December 2004. As of 27 December 2005, four crossover specials have been aired, comprising nine episodes total. Although further crossovers of storylines and characters have since occurred, they have not been broadcast under the Casualty@Holby City title.

## Production

The suggestion to produce the first Casualty and Holby City crossover originated from a member of the BBC comedy department. The station's Controller of Drama approved of the idea and had the crossover commissioned, spearheaded by Casualty's executive producer Mervyn Watson, and Holby City's Tony McHale. The writer and producer for the first, two-part crossover were selected from the Holby City crew. Logistical difficulties arose from the fact the two series are usually produced 120 miles apart, with Casualty based in Bristol and Holby City in Elstree. Both series are usually in continuous production 52 weeks a year, so in order to produce the first crossover, work on both shows has to be halted for two weeks to release a number of cast members to appear in the special. Once regular production began again, the availability of cast members set to appear in the crossover was limited, and both series had to rely for the most part on the remaining characters who were not in the special. Filming took six weeks to complete, and occurred for the most part at Casualty's emergency department in Bristol. Additional filming took place at the Holby City set in Elstree, as well as the Queen Elizabeth Hospital for Children, a Barratts office block in Brentford and an ex-MOD tank testing site in Chobham. A theme tune was devised, consisting of both the Casualty and Holby City theme tunes played over one another in sync. Terry Ramsey of the Evening Standard described it as "shambolic", opining: "it sounds like it was produced with The Big Boy's Box of Sound Mixing software by a seven-year-old on Christmas Day while playing his PlayStation with the other hand."
A second crossover was commissioned in 2005 as part of the BBC's DoNation season. In August 2005, the station ran a week-long campaign to raise public awareness of organ donation, aiming to help viewers make an informed decision about whether to sign up to the Organ Donation Register. An interactive episode of Casualty@Holby City was one of the headlining shows of the season, allowing viewers to vote by phone to determine the outcome of a fictional organ donation. The episode was part documentary, and a segment presented by Robert Winston both detailed the guidelines for matching organ donors with recipients, and dispelled common myths about organ donation. Viewers were then invited to vote for one of two characters to receive a heart transplant. 98,800 viewers voted, with a 65 percent majority favouring that the organ be received by Lucy, a young cystic fibrosis patient, over Tony, a widow twenty years her senior. Two different endings were filmed, to account for both possible outcomes of the public vote. The alternative ending was made available on the Casualty@Holby City DoNation Interactive website.
The third Casualty@Holby City crossover was aired in October 2005, two months after the interactive special. The four-part storyline tackled the issue of youth violence, following the events of a turbulent A&E demonstration at an inner-city school. The crossover was broadcast in the same week that the BBC launched a new adaptation of Charles Dickens' Bleak House starring Gillian Anderson and Charles Dance, and Phil and Grant Mitchell returned to the station's soap opera EastEnders. BBC1 controller Peter Fincham explained: "We have got three very different dramas playing this week that emphasise the breadth and depth of what we have to offer. Changing the scheduling of established favourites and the format for presenting period drama is exactly what I want BBC1 to be doing, challenging our audiences with top quality programming."
Based on the success of the 2004 Casualty@Holby City Christmas special, another crossover was ordered for Christmas 2005. Rather than dividing the episodes between the two series' crews as had previously been standard, this crossover operated as an entirely separate production, with Diana Kyle producing and Paul Harrison directing. A large proportion of the crossover was filmed in a road tunnel in Caernarfon, Wales. Watson commented: "It was the only one that we could hire for two weeks without causing huge traffic jams. The whole shoot was five weeks long. Staging stunts like car accidents is difficult and stressful at the best of times, but doing all that in a tunnel doubled it. The great advantage was that there was no problem with the weather, it was a totally controlled environment with excellent parking facilities for the unit, and a warm welcome from the locals, which is always nice."

## Reception
### Critical response

Casualty@Holby City episodes have received mixed reviews from critics. Terry Ramsey of the Evening Standard selected the first episode as a televisual "Pick of the Day". The inaugural crossover was named one of the "Best TV shows for Christmas & New Year" in The Mirror, receiving generally favourable reviews by Mirror writers Jane Simon and Jim Shelley—despite the former lambasting the realism of the plot: "The building collapses, there's a little girl upstairs about to have a heart transplant, the tanker's leaking fuel and there's a velociraptor loose in radiology. Sorry, I made that last one up."—and the latter commenting that "Casualty@Holby City was deeply weird, like watching Casualty on acid." Similarly, Daniel Davies of The Western Mail also selected the episodes as dramatic highlights of the Christmas season, despite going on to discuss the aptness of the BBC's press release describing the two episodes as "thrown together."
Other reviews were more openly negative, with Charlie Brooker of The Guardian describing the episodes as "two virtually identical and rubbish shitcasts for the price of one." Frances Traynor of the Daily Record commented similarly that: "It can be quite difficult to tell these medical drama twins apart. After all, they're both rubbish", while the Liverpool Echo's Paddy Shennan suggested "the blood should instead be flowing in the BBC boardroom" for commissioning the crossover. Thomas Sutcliffe of The Independent called the crossover "the funniest programme on television", with a "sublimely cloth-eared script", describing it as: "A masterpiece of sustained comic timing [which] had this casual viewer of the dramas that spawned it scrabbling wildly for an explanatory hypothesis."
The interactive episode was deemed "a horrible mess" by Shelley, while Garry Bushell of The People kept his criticism brief, limiting his review to: "Casualty@Holby City? Takings up@pub." Paul Hoggart of The Times was dubious about the episode's purported "interactive" element, given the limited choices involved. He commented: "The twin hospital dramas have never been afraid of didactic storylines, but this example, constructed to illustrate the ethical dilemmas of those involved, is about as didactic as it gets. Let's hope this benevolent propaganda works."
The four crossover episodes which broadcast in November 2005 were generally well received by the press. The opening episode was a recommended "TV Choice" of The Daily Telegraph's Chris Riley, a "Pick of the Day" of The Mirror's Simon, and a "Pick of the Night" of the Evening Standard's Ramsey. The crossover was also a "Drama Choice" of Sarah Moolla of The People, who commented that: "There's something weirdly thrilling when these two medical shows collide."
The Christmas 2005 episodes were less favourable received, described by David Chater of The Times as: "Intentionally or not [...] one of the comic highlights of Christmas." Paul English of the Daily Record deemed the crossover: "Two turkeys for the price of one", while Terry Ramsey of The Evening Standard wrote that: "even by Casualty and Holby City standards, this one is boringly formulaic. A monotoned, badly paced, cornily written, unexciting (despite its most desperate efforts), predictable, high-pitch squeal of a drama. For die-hard fans only." The Daily Post were more positive, stating that the episodes "will have Casualty and Holby City fans glued to their TV sets over the festive period."

### Ratings

The December 2004 Casualty@Holby City crossover received strong ratings. The first episode averaged 8.91 million viewers, making it the third most watched terrestrial programme of the day. The second episode was watched by 8.82 million viewers, making it the second highest rated terrestrial programme of the day. The interactive donation episode, "Something We Can Do", attained 7.32 million viewers, again making it the second most watched terrestrial programme of the day, and also the BBC's second best rated programme of the week, behind only EastEnders.
The October 2005 episodes received the lowest ratings of any Casualty@Holby City crossover to date. On its opening night, the show was watched by 5.56 million viewers, in contrast to the ITV soap opera Emmerdale, which were shown in the same timeslot and attained 9.1 million viewers. The remainder of the Halloween crossover received similarly low ratings, with the second episode watched by 5.96 million viewers, the third instalment by 4.57 million viewers, and the concluding episode by 5.64 million viewers. The fourth Casualty@Holby City crossover saw a ratings revival, with the third episode watched by 8 million viewers, making it the third most watched terrestrial programme of the day, and the second episode watched by 8.82 million viewers, becoming the second most watched terrestrial programme of the day.

## Future

Asked about the potential for future crossover episodes, Watson stated in 2005: "We can't guarantee any crossovers for next year, but the audience likes them. And as long as the controller of BBC One wants them, then we'll be happy to oblige." In November 2007, Kyle re-iterated that the separate series' 52-week filming schedules make it logistically difficult to produce crossovers, but revealed that the production teams were trying to create more opportunities for the two shows to merge. A new set of crossover episodes written by Casualty's lead writer Mark Catley were planned for February 2010. In the event, however, the episodes which saw Casualty's Charlie Fairhead (Derek Thompson) operated on by Holby City's Elliot Hope (Paul Bradley) after suffering a heart attack were broadcast as regular Casualty and Holby City episodes, rather than under the Casualty@Holby City title.
Since then, characters periodically crossover typically for a single episode at a time to fit an ongoing storyline. This has proved popular among fans and is logistically more practical than previous crossover events. In more recent years, characters have attained different positions within the hospital which sees them crossover permanently. Connie Beauchamp began appearing permanently in Casualty in March 2014 following her departure from Holby City in December 2010. Fletch departed Casualty in June 2014 before appearing permanently on Holby City from August the same year. Lee Mead portrayed Lofty on Casualty from March 2014 to March 2016. Following his departure, it was announced Mead would be reprising his role in Holby City from April 2017.
Another smaller scale crossover event was broadcast in August 2016, in "Too Old for This Shift" and "Protect and Serve" The episodes were co-written by Matthew Barry and Andy Bayliss (Casualty) and Steve Brett and Joe Ainsworth (Holby City). The episodes follow on from the cliffhanger at the end of the thirtieth series, by focusing on the events surrounding the aftermath of an accident involving Connie Beauchamp (Amanda Mealing) and her daughter Grace (Emily Carey), including a helicopter crash outside Holby City Hospital's emergency department, during celebrations of Charlie Fairhead's (Derek Thompson) thirtieth year working at the hospital.
Another series of crossovers was implemented in late 2017, with a number of characters that swapped over for episodes.
Another crossover happened in 2019 called CasualtyXHolby this centred around Holby City Hospital experience a loss of power due to a cyberattack. Consultants Connie Beauchamp (Amanda Mealing) and Jac Naylor (Rosie Marcel) also come into conflict when they learn there is only one theatre available while treating two of their colleagues.
