Leading actress Sian Reese-Williams commented that the series was more of a "personal drama" than a crime series, because of the multiple human stories involved, including those of the victims, the families of the victims, and the criminal protagonist.[2]

Filming and releaseEdit

Filming took place in 2017 in Bangor and Snowdonia.[3] The series was the second project on which Andrew and Talfan collaborated, following Hinterland. It was first broadcast as Craith, in Welsh, on S4C on 7 January 2018 and aired weekly.[4] A bi-lingual version of the series aired, mainly in English, on BBC One Wales and BBC Four in June 2018 under the title of Hidden.[5][6][2]

Hidden was renewed for a second series in February 2019.[7] It broadcast first on S4C on 17 November 2019.

In January 2021, the BBC announced that a third series had been commissioned to air later in the year, with Sian Reese-Williams and Siôn Alun Davies returning in their roles of, respectively, DCI Cadi John and DS Owen Vaughan. The number of episodes comprising the series was unspecified.[8]

The Guardian compared Hidden favourably to the Swedish Scandi-noir drama The Bridge, describing it as one of the "current powerhouse run of Wales-set dramas", with "scenes in Welsh to provide that sweet Nordic subtitles hit".[9] It went on to say "Hidden is perhaps the most confidently stylish and stylised yet. As well as a gorgeously gothic credits sequence, it features handsomely brooding landscapes, offbeat interior locations that go far beyond the usual bland corridors/offices of cop drama, and an ominous, skin-prickling soundtrack skilfully employed to heighten the sense of dread."[9]
