As most people now know (and certainly regular readers of this blog), most of the filming for Midsomer Murders is done in Southern Oxfordshire and the surrounding areas. Wallingford, Henley and Dorchester, amongst others, double up for the fictional town of Causton and the Midsomer region in general on the show. So, when you’re watching your favourite episodes, you know what’s what in the background.

However, can the same be said for the characters of Barnaby and DS Charlie Nelson? OK, so we all know that they’re perfectly played by Neil Dudgeon and Gwilym Lee, and a quick Wikipedia search can tell you all you need to know about them, but how about the characters themselves? How did they come to end up in Midsomer?

In a recent interview, Neil shed some more light on to Barnaby’s background. The 53-year-old said: ‘John Barnaby has a degree in psychology and his approach to his work comes from his interest in criminals and why they do what they do. He plays his cards close to his chest and adapts his persona to get results, even if it means he has to look weak or silly. He is also quite direct and has a likeable black sense of humour, which helps him get through the darker moments.’.

Commenting on the locations, Neil added: ‘The locations are vital, seeing all the beautiful English countryside, vast stately homes and sweet little cottages.’

In the same interview Gwilym revealed a bit more about Charlie too: ‘DS Nelson is from the city and he finds village life and the pace a bit different; it’s daunting how everyone knows everyone else’s business. He comes in with lots of police jargon and tends to talk too much. He likes green tea and is a bit of a health freak, getting up at 6am to go for a run. He’s a modern guy – he can cook and keep the house tidy and look after himself.’

So, now you can add a little story and background to the characters, while you’re enjoying the story and background on screen.
