# Hinterland (TV series)

Hinterland — Y Gwyll (Welsh for 'the dusk') in the original Welsh language version — is a Welsh Language noir police procedural series broadcast on S4C in Welsh from 29 October 2013. The main character, DCI Tom Mathias, is played by Richard Harrington. On 27 November 2013, a second series was announced by S4C. The English-language version, with brief passages of Welsh dialogue, aired on BBC One Wales. When it was shown on the BBC in 2014, it was the first BBC television drama with dialogue in both English and Welsh. A third series of the show began filming in January 2016 and debuted on S4C on 30 October.
The programme is set in Aberystwyth, Ceredigion, Wales, and the three series were filmed in and around the town, often in rural locations. The critical reaction to Hinterland was favourable. Wales Arts Review wrote: "Y Gwyll has been shot with real intelligence; simple, subtle and with both eyes focused on the feeding of the atmospheric cloud over the piece." Hinterland was subsequently shown in 150 countries.

## Production

The series reflects the commitment made in April 2013 by the Director of BBC Cymru Wales, Rhodri Talfan Davies, to show more Welsh language, life, and culture on the mainstream BBC channels.
On a tight budget, funds that took two and a half years to raise, the total production cost was £4.2 million. The programme-makers received £215,000 in repayable business funding from the Welsh Government, and the first series was mainly filmed in Aberystwyth and the surrounding county of Ceredigion on the west coast of Wales, over a 124‑day period in 2013. The show was filmed in both Welsh and English, with the location-based production offices contained within the former Ceredigion Council offices Swyddfa'r Sir, which also acts as the exterior of the show's police station.
Each scene was filmed twice, in the English and Welsh languages, apart from a few scenes where Welsh with subtitles is used for the English version.
The Welsh version was broadcast (in eight parts) on S4C in October 2013, with the bilingual version (in four parts) broadcast on BBC One Wales in January 2014 and on BBC Four later that year. Danmarks Radio (DR), acquired the rights in 2012 to broadcast the show in Denmark, before filming had commenced.

As the investigation draws DCI Mathias into the heart of the close-knit community, he discovers that Reynolds was having an affair with the wife of the local pub landlord, and was taking the son of one of his co-workers deep into the forest to visit an hermetic villager, who some years previously had torched his own home and nearly killed his estranged wife and two children. ||||||

As Mathias begins to grow close to the girl's grieving mother, he finds the investigation has missed one key suspect, Iwan Thomas.
