Casualty series 31

The thirty-first series of the British medical drama television series Casualty commenced airing on BBC One in the United Kingdom on 27 August 2016, and concluded on 29 July 2017. The series consisted of 44 episodes, including the show's feature-length thirtieth anniversary special episode, "Too Old for This Shift". Erika Hossington continued her role as series producer, while Oliver Kent continued his role as the show's executive producer until the end of the series. Seventeen cast members reprised their roles from the previous series with original character Lisa "Duffy" Duffin returning to the series as part of the show's thirtieth anniversary. Rik Makarem appeared in the series between October 2016 and January 2017 as first year foundation doctor (F1) Sebastian Grayling. This series also featured the death of regular character Caleb Knight (Richard Winsor), who has appeared since series 28.

The opening episode of the series was a special feature-length episode, celebrating thirty years of the medical drama. The episode featured main character crossovers from Holby City, with Jac Naylor (Rosie Marcel), Henrik Hanssen (Guy Henry) and Adrian "Fletch" Fletcher (Alex Walkinshaw) appearing in the episode. Various former characters who have appeared in previous series throughout the thirty years of broadcast also made guest appearances during the episode. The episode features both the main characters lives, and the hospital itself in danger when an air ambulance crashed in the emergency department car park. The episode was watched by 7.20 million viewers. A special soundtrack was recorded for the episode, by the BBC National Orchestra of Wales. The series concluded with a special episode, "One", filmed in a single-take, using one camera, forty microphones and five boom operators. Show co-creator Paul Unwin returned to the show to write the episode.

The series was well received by fans and critics alike. They enjoyed the opening episode and opined that the show deserved an award, but an air ambulance charity thought the episode was thoughtless. On 25 January 2017, Casualty was awarded Best Drama at the National Television Awards. On 11 April 2017, the show was nominated for Best Soap & Continuing Drama at the BAFTAs, but was unsuccessful. The helicopter crash won the award for Best Drama Storyline at the 2017 Inside Soap Awards; Charlie and Duffy's wedding and Cal's murder also received a nomination in the category.

Production
Oliver Kent continued his role as executive producer, whilst Erika Hossington remained as the series producer. Kent was appointed Head of Continuing Drama Series for BBC Scripted Studios in late 2016, with Simon Harper, series producer of Holby City at the time, subsequently being appointed acting executive producer of both shows. Harper was later promoted to the show's official executive producer on 8 June 2017, although Kent was credited in the role of executive producer until the end of the series. Mark Catley, the show's story consultant, was credited as co-executive producer for the first episode only. The thirty-first series consisted of 44 episodes.

The feature-length anniversary episode that began the series, aired for 99-minutes on 27 August 2016, and featured a storyline event that connected Casualty with its sister show Holby City. The BBC National Orchestra of Wales recorded a special soundtrack for the episode at BBC Hoddinott Hall in Cardiff Bay. Plans for the special were teased back in August 2014, when Hossington hinted that the show would do something "no other show had done before". In an interview with What's on TV, Charles Venn revealed that his character, Jacob Masters, would have a key role in the anniversary special. He added that cast and crew members were nicknaming the episode "Casualty: The Movie" while it was being filmed. Kent later stated that the episode would make the audience "gasp, laugh and cry buckets".

Hossington teased the series finale in an interview with Sophie Dainty of Digital Spy, promising to give viewers "a live experience" without making a live episode. She described the episode as "special and unique" and said it would be "something that the show has never, ever done before." Hossington also promised several stunts, including a "really big falling stunt within the hospital" in the latter half of the series. Further details on the series finale were revealed on 5 April 2017, where it was announced that the episode, "One", will be shot in a single-take, using one camera, 40 microphones and five boom operators. The finale was one hour long and was written by the show's co-creator, Paul Unwin. Hossington said the special episode would "give the audience a unique insight into an hour in A&E". She added that the episode would be "intense" and "emotional".

Critical response
The anniversary episode received strong praise from fans. Radio Times reported that viewers were left "stunned" by the episode, while Digital Spy stated that fans were left in "shock and awe" over the episode. The Daily Mirror reporter Sharon Marshall praised the episode, branding it as a "pitch-perfect episode mixing gore, heartache, drama and nostalgia". Marshall added that the episode "showcased what Casualty does best – beautiful writing and a stellar cast who grab your heartstrings," before concluding her review by praising the episode as being able to make the show "look as fresh and exciting as the day it was born." However, the show also received criticism, with the episode being branded "insensitive" by the Midlands Air Ambulance Charity.

The final episode of the series received a mixed reception. Alison Graham, writing for the Radio Times, described the episode as a "bold piece of television" and praised the show for displaying "the chaos of a front-line service". Jessica Ransom of What's on TV enjoyed the episode and was impressed that there were no mistakes. She said the episode highlighted the "ever chaotic trauma" and a "particularly explosive day" in the emergency department. Michael Hogan of The Daily Telegraph wrote a review on the episode, awarding it a score of 3 out of 5. While he thought that the fly-on-the-wall theme created "intensity and realism" within the episode, he opined that some speeches from the characters "didn't quite work" and found the explanations during the episode "jarring". He praised the decision to have original cast members, Shipton and Thompson, lead the episode, but commented that the episode was "let down by a clunking script that needed some doctoring of its own."

Broadcast ratings
Ratings for series 31 of Casualty averaged at 5.61 million viewers, an increase on the previous series. The opening episode received an overnight rating of 5.10 million viewers, a 26% share of the total audience. BBC Media Centre later revealed the episode was watched by an audience of 7.20 million viewers. The single-take episode that concluded the series received a 28-day rating of 6.57 million viewers. Episode 1 is the highest-rated episode of the series, while episode 31 is the lowest-rated episode of the series with a rating of 4.73 million viewers.

Awards and nominations
On 25 January 2017, Casualty was awarded Best Drama at the annual National Television Awards. The show was shortlisted against Cold Feet, Game of Thrones, Happy Valley and The Night Manager. On the win, Shipton commented, "I'm not that surprised we won tonight. I'm a newbie and the strength of the cast and the writing and the passion behind that show is on screen and that's why they voted for us." Hossington called the reaction to the win "electric" and said it had "a huge impact on everybody". She added that the show's team were "so chuffed that the sheer love and hard work that they put into the show has been appreciated by the audience and the fans". The win also received criticism from those who believed that Casualty should be classified as a soap opera and not entered into the category.

It was announced on 11 April 2017 that Casualty had been nominated for a BAFTA award under the Soap & Continuing Drama category. ITV soap opera Emmerdale won the accolade. The helicopter crash, Charlie and Duffy's wedding and Cal's murder were shortlisted for Best Drama Storyline at the 2017 Inside Soap Awards. On 6 November 2017, the helicopter crash won the "Best Drama Storyline" accolade. Casualty was shortlisted in the "Best Soap/Continuing Drama" category at the 2018 Broadcast Awards, but lost out to Channel 4 soap opera Hollyoaks. Judges praised the "truth and sensitivity" involved in Robyn's premature birth storyline and found the use of puppets as Robyn's baby "amazing".
