Series 31

Series 31 will be the thirty-first series of Casualty and commenced airing on 27 August 2016. The current series producer Erika Hossington revealed that they had big plans for the show's thirtieth anniversary, which fell at the beginning of this series. It was later revealed that the 30th anniversary episode was to air on 27 August, 10 days before the actual anniversary. The series will contain 43 episodes, the same as the previous series.

When asked about the cast, Hossington stated that viewers can expect to see a few new faces later in the year (2016), which will likely be in series 31. Amanda Mealing, who portrays Connie Beauchamp, directed episode 10 of the 31st series.

This series introduced a brand new title sequence and a slightly new theme tune, although the changes to the latter were minimal. In a photo posted by one of the writers to Twitter, Elle is shown at the top with "Clinical Lead" written under her name, proving she will replace Connie in that role. Elle will take up the role of Clinical Lead following Connie's temporary departure.

Series guest appearances
The series opener will see a variety of guest appearances from former cast members including Ian Bleasdale and Suzanne Packer as Josh Griffiths and Tess Bateman, respectively. Charles Dale will also return for a brief cameo in the episode as MacKenzie "Big Mac" Chalker who departed just two months earlier. Some Holby City regulars will also guest star in the 30th anniversary episode, including Jac Naylor, Henrik Hanssen and Adrian "Fletch" Fletcher, the latter having been a series regular on Casualty from 2012 to 2014. Continuing into series 31 will also be Robyn's love interest Glen Thomas as well as Steph and Carmel Sims. Emily Carey will also appear in the opening episode as Grace Beauchamp, continuing her recurring role which began in the 29th series. It's currently unknown whether her character will survive past the first episode.

In August, Josh Griffiths' guest appearance was officially announced as well as the news that Ben Turner had reprised his role as Jay Faldren for the 30th anniversary. On 16 August, it was revealed that Alice Chantrey, John "Abs" Denham, Mike Barratt, Comfort Jones and Lenny Lyons would all appear in episode 1 along with the other returnees. James Gaddas and Tracey Wilkinson guest starred in episode 2 as Alicia's parents Howard and Jackie Munroe, respectively.
