Here are some of the most common filming locations:
* The Lyceum Theatre in London's West End is used as the main location for the fictional Lyell Centre, the forensic pathology lab where the characters work.
* Shepperton Studios in Surrey is also used for filming interior scenes, especially the lab.
* Various locations across London are used for exterior shots, including streets, parks, buildings, and landmarks.
* Locations outside London are used for specific episodes that feature storylines in different parts of the UK.
The specific locations used in each episode vary depending on the story, but the show is generally rooted in London.
