Each new series of Silent Witness sees the team sent off to brand-new locations, and in 2020 there are lots more in store.
According to producer Lawrence Till, series 23 will feature everything from a plane crash to a cryogenics centre, as well as chemical labs and army barracks and idyllic villages.
Here’s what you need to know…
Where is the women’s refuge filmed?
Episodes five and six, titled Seven Times, are set at locations across London – but the storyline centres around a women’s refuge.
Lawrence Till told us: “Seven Times is about domestic violence, it’s about a group of women who all meet in a women’s refuge – and it’s sort of a set of different stories, but we discovered that they’re all linked by the refuge. And then, Nikki has a personal memory of abuse in her family between her parents, which ties her into that story.”
The women’s refuge was filmed on-set in Ealing at the London Drama Studio.
Boston Manor Service Station was used to recreate the interior of the garage where Brian Collyer (Geoff Bell) works, while nearby Boston Manor Park was the location of the children’s playground.
There’s also a scene between couple Jade (Seraphina Beh) and Lucie (Alexa Davies) filmed at The Tea House in Ravenscourt Park Mansions, and a train platform scene shot at Princes Risborough Railway Station.
The family court scenes (interiors and exteriors) were shot at Surrey County Council.
Where was Close to Home filmed?
In episodes three and four, Close to Home, Dr Chamberlain & co. must work out who killed Jason Forbes – a young boy who disappeared on his way home from judo training, and whose body has just been found. The victim is from the village of Hartford, which lies outside the Lyell Centre’s usual jurisdiction – but Assistant Commissioner Tim Holloway (Tom Goodman-Hill) has specially requested their help on the job.
Hartford is actually fictional, but Till and his team filmed much of the episode in the village of Shere. Full of traditional buildings, Shere is located in Surrey and formed the perfect backdrop.
Till said: “We used the centre of the village, Sheer village itself, and then we used the church there. And we used a number of domestic locations across the village.”
Filming took place at South Mimms Service Station, and at St James Church, and at Pulleyn Transport Ltd (which stood in for Faulkner Haulage). The barn at Painshill Farm was used to paint a picture of the fictional Mayhew Farm, and Hurley Riverside Park was used for the scenes set on the caravan site.
The interior of New Scotland Yard was filmed at Westminster College.
Where was the plane crash episode filmed?
Silent Witness starts off very dramatically this year, with a business jet plunging from the skies and crashing into the trees, tearing itself apart and killing multiple pilots and passengers. It’s such a “big-scale” stunt, in fact, that David Caves (Dr Jack Hodgson) has compared it to a Bond film.
The crash kicks off a double bill called Deadhead. And while our forensics experts team up with the police and the Air Accidents Investigation Branch (AAIB) to work out what happened, there’s also a personal angle for Dr Nikki Alexander (Emilia Fox); one of the crash victims is the former US ambassador – who also happens to be friends with her boyfriend, Matt Garcia (Michael Landes).
The plane interior was filmed at Shoot Aviation Ltd in Maidenhead, a facility which handles a ton of the aviation-related scenes you’ll see on TV and in movies – from The Capture to the Kingsman movies to Wonder Woman 84, Cold Feet, the Night Manager, Black Mirror, and many more.
Shoot Aviation Ltd was also used to film the interior of the hangar in Farnborough, where the AAIB’s Jess Fisher (Emma Cunliffe) and her team of experts have collected all the pieces of the private jet and laid them out to help with their investigation.
The actual crash site and the debris field which we see still smouldering when the Lyell team arrive at the scene was filmed around Shoot Aviation HQ in Maidenhead, in nearby fields and woodland.
The episode also includes scenes set in a hotel, which were filmed at the Clayton Hotel on Chiswick High Road in London, and hospital scenes filmed at Guy’s Hospital.
A sequence showing Nikki’s boyfriend Matt at the airport was filmed at Heathrow Terminal 2.
Where is the Lyell Centre filmed?
The Lyell Centre is located in a warehouse at BBC Park Western in Acton, where a permanent set was built seven years ago.
This is now official Silent Witness HQ with the art and props departments based in the building and ready to provide fake blood and cadavers on demand.
