Speaking to HELLO! at the show’s London premiere in January, Kelly revealed what drew her to the role. “I was moved by it when I read it. I found it incredibly haunting,” she said.

“When you see in the news about a child being taken when they were five, six years old, and 30 years later the parents are still wondering what happened to them, it’s incredibly devastating.”

What have viewers said about the show?

After just two episodes, viewers are already glued to their screens. One person wrote: “Gripped by #UnderSaltMarsh. Clever, plotty, brilliant Welsh drama. Need all episodes now – so good,” while another compared the series to ITV’s hit drama Broadchurch, adding: “This has a Broadchurch feel to it. So far so good.”

A third viewer penned: “Under Salt Marsh is a superb addition to Sky Atlantic’s crime drama catalogue and one that deserves serious attention. Tense, emotionally rich, and beautifully shot, this is slow-burn television done right,” while another praised the performances as “superb”, adding: “the moody Welsh atmosphere has me hooked.”

It’s no surprise that viewers are loving the series. Not only does the show boast a seriously impressive cast list, but it comes from Little Door Productions (The Pact) and Sky Studios, which is known for its impressive list of original dramas, including Gangs of London and The Lazarus Project.
