Yellowstone’s Kelly Reilly Steps Into Dark New Crime Drama Under Salt Marsh
Kelly Reilly, best known as the fierce Beth Dutton in Yellowstone, is returning to British television in a gripping new crime series. She will co-lead Under Salt Marsh, a Sky Original drama set to premiere in the UK in 2026. First-look images have already sparked excitement among fans.
Reilly is no stranger to the genre. Many will remember her as Detective Constable Anna Travis in ITV’s Above Suspicion. Now, she takes on a very different role. In Under Salt Marsh, Reilly plays Jackie, a woman forced to reunite with her estranged police partner, Eric Bull, played by Timothy Spall.
The synopsis teases a story full of tension: Jackie and Eric dive into a haunting investigation in the fictional Welsh coastal town of Morfa Halen. Their search uncovers secrets and grief buried deep within the community, all while a violent storm threatens to erase the truth forever.
The newly released images capture the show’s moody atmosphere. One shot places Jackie on a rain-soaked night, her face marked with exhaustion and resolve. Others show Jackie and Eric combing through the coastline, hinting that the beach will play a central role in the mystery.
What This Role Means for Reilly After Yellowstone
Under Salt Marsh marks Reilly’s first major TV project since Yellowstone ended in 2024. Unlike the ruthless, fiery Beth Dutton, Jackie seems far more vulnerable. The character is desperate, grief-stricken, and possibly broken, offering Reilly a chance to reveal a new side of her craft.
This return to British television feels like a natural homecoming. Reilly has worked in crime and mystery before, including her role in Kenneth Branagh’s A Haunting in Venice. But Under Salt Marsh promises a darker, more layered performance.
Why Under Salt Marsh Could Be a British TV Hit
British crime dramas excel at telling sharp, emotional stories in just a few episodes. From Broadchurch to Sherwood and Karen Pirie, the best series blend present-day mysteries with old wounds, showing how violence reshapes entire communities. Under Salt Marsh looks ready to join that tradition, combining a tense investigation with deeply personal stakes.
For Kelly Reilly, it’s more than a new role—it’s a chance to redefine herself beyond Beth Dutton. And for viewers, it’s another reminder that few do crime drama quite like the Brits.
