First look at new Welsh crime drama starring Yellowstone actor
Sky’s Under Salt Marsh stars Kelly Reilly – who plays Beth in the Western series Yellowstone on Paramount – as former detective Jackie Ellis, now a teacher after an unsolved case shatters her family and work life.
Welsh actors Sir Jonathan Pryce, best know for The Crown, and Fresh Meat’s Kimberly Nixon also feature in the cast.

The six-part crime drama, that was filmed on Anglesey and across Gwynedd, has been praised by critics ahead of its release at the end of January.
Under Salt Marsh is based in the fictional Welsh town of Morfa Halen – which means Salt Marsh in Welsh.
Aberffraw is one of the settings for the crime drama and can be seen in the show’s trailer, with filming taking place in the village on Anglesey early in 2025.
In Gwynedd, the cast were spotted filming on Barmouth’s promenade in October 2025, with further scenes filmed in Fairbourne and Llanbedr.
Known for playing Prince Philip in Netflix’s The Crown, Sir Jonathan Pryce plays Solomon Bevan.
Also part of the cast are Harry Lawtey, who played Richard Burton in the film Mr Burton, and Welsh actors Dino Fetscher, Rhodri Meilir and Julian Lewis Jones.
The series starts as the town prepares for a once-in-a-generation storm, and Jackie discovers the body of her eight-year-old pupil, Cefin, seemingly drowned.
The community is left reeling and can’t help but be reminded of the unsolved disappearance of Nessa, Jackie’s niece, who went missing three years prior.
Jackie is reunited with her old partner, Det Eric Bull, who has been brought back to lead the investigation and who has something to prove to the residents of Morfa Halen who he failed before.
Netflix is removing The End We Start From, a 2023 British drama starring Jodie Comer as an unnamed new mother who tries to survive when Great Britain is flooded. The last day to watch it on the streamer is this Sunday (18 January).
At the time of writing, it’s not available as part of any other streaming subscription.
Directed by Mahalia Belo (Requiem) and written by Alice Birch (Succession, Anatomy of a Suicide, Normal People), the film is an adaptation of Megan Hunter’s 2017 novel of the same name.
It boasts an impressive cast, with Comer joined by Benedict Cumberbatch, Our Flag Means Death’s Joel Fry, Screw’s Nina Sosanya, Kingsman’s Mark Strong, Alien: Covenant’s Katherine Waterston, Emmerdale and EastEnders’ Phillipa Peak, and SAS Rogue Heroes’ Theo Barklem-Biggs.
And it turns out that the cast weren’t wasted on a duffer, as The End We Start From was very well acclaimed by critics.
