Neil Dudgeon has joked he is worried Midsomer Murders fans won't recognise the latest episode of the show - as the opening scene couldn't be less provincial.

The hit ITV crime drama has teamed up with stars from Danish shows Borgen and The Killing for special episode The Killings Of Copenhagen, to celebrate its 100th episode.

Neil, who plays DCI John Barnaby, told the TV Times: "I'm pretty certain the previous 99 episodes have opened in a cottage or a country church, whereas this one begins in a hotel in Radhuspladsen, the square in front of Copenhagen's City Hall.

"I think some viewers will think they've tuned in to the wrong programme!"

The episode sees a Midsomer biscuit factory owner found poisoned in Copenhagen.

DCI Barnaby and his sidekick Detective Sergeant Charlie Nelson (Gwilym Lee) will team up with Copenhagen cops DCI Pulsen, played by The Killing's Anna Eleonara Jorgensen and Detective Sergeant Degn, played by Borgen's Birgitte Hjort Sorensen, to investigate.

Neil revealed: "They're like a female Barnaby and Nelson whom we are seconded to for the investigation."

And Gwilym revealed Nelson's plans to impress their new colleagues, by learning some Danish phrases, does not go down as well as he planned.

He explained: "The language doesn't sound anything like what it looks on paper. I think they have about three sounds that don't even exist in English."
