New S4C Crime Drama Begins Filming

S4C has begun filming for the new six-part crime drama Cleddau/The One That Got Away.

The show combines a murder mystery with a love story. From BlackLight (a Banijay UK company) in collaboration with Banijay Rights, the series is being filmed in Welsh for S4C for broadcast in late 2024, while an English-language version will also be produced for international audiences.

The series is written by Catherine Tregenna (The Bench) and stars Elen Rhys (The Mallorca Files, Craith/Hidden), Richard Harrington (Y Gwyll/Hinterland) and Rhian Blythe (Y Golau/The Light in the Hall, Craith/Hidden). All six episodes are directed by Carmarthenshire-born Sion Ifan (Y Gyfrinach/The Secret).

Both the English and Welsh versions of the show will be distributed globally by Banijay Rights.

Treganna said: “I’m so excited to create and write my own series and share it with S4C audiences, as that’s where my television career began. It’s a privilege to write in the voice and accents that are part of my childhood and bring to bear what I’ve learnt in over 25 years of writing crime thrillers.”

Gwenllian Gravelle, S4C drama commissioner, added: “We’re delighted to be working alongside Banijay and BlackLight on such a suspenseful series. We can’t wait for our viewers to watch this tense, gripping crime thriller, which never once loses momentum. With a stellar Welsh cast and a fabulous location, it’s going to be a real treat.”

Phil Trethowan and Ben Bickerton, executive producers at BlackLight, said: “We are thrilled to be making Cleddau/The One That Got Away with S4C, Banijay Rights and Creative Wales. It is a gripping thriller that will keep the audience guessing until the end, delivered by the very best Welsh writing, directing and acting talent.”

Simon Cox, executive VP of content and acquisitions for Banijay Rights, commented: “Set against the backdrop of the beautiful West Wales coast, Catherine Tregenna’s superbly crafted crime story is a fantastic addition to the Banijay Rights catalogue—marking our foray into the burgeoning Welsh noir genre. We are excited to partner with BlackLight and S4C on the dual language versions of Cleddau and take this gripping drama to audiences worldwide.”
