Yellowstone’s Kelly Reilly Stuns in First Look at New Crime Drama Under Salt Marsh
Kelly Reilly, best known as the fiery Beth Dutton on Yellowstone, looks almost unrecognisable in her latest role — and fans are already buzzing. The British actress has swapped the grit and glamour of Montana ranch life for the windswept Welsh coastline in Sky’s upcoming six-part thriller, Under Salt Marsh.
From Beth Dutton to Jackie Ellis
In a major departure from her iconic Yellowstone character, Reilly plays Jackie Ellis, a former detective turned teacher whose life is shattered by a cold case that cost her career and her family’s trust. Vulnerable yet determined, Jackie finds herself drawn back into danger when startling new evidence reopens the investigation.
Forced to reunite with her estranged partner Eric Bull (played by Rafe Spall), Jackie must navigate a town haunted by secrets, grief, and suspicion. Together, they race to uncover the truth before an incoming storm washes away crucial evidence.
First Look: A Striking Transformation
The newly released first-look stills showcase a very different side of Reilly. One haunting image shows Jackie braving a storm, torch in hand, her face etched with fear and resolve — a far cry from Beth Dutton’s sharp-tongued swagger.
Another still captures Jackie and Eric’s tense reunion on the Welsh coast, their fractured partnership mirroring the uneasy community they’re investigating.
The shift is striking: Beth Dutton was a force of chaos and control, while Jackie Ellis is portrayed with quiet resilience, vulnerability, and raw humanity.
A Must-Watch Thriller With a Powerful Creative Team
Created, written, and directed by Claire Oakley (Make Up), Under Salt Marsh blends atmospheric crime drama with an intimate exploration of resilience and community. The series promises haunting landscapes, a gripping mystery, and layered performances.
The supporting cast is equally impressive: Jonathan Pryce (The Crown), Harry Lawtey (Industry), Naomi Yang, Dinita Gohil, Brian Gleeson, and Kimberley Nixon.
Reilly’s Busy Post-Yellowstone Era
Under Salt Marsh marks one of Reilly’s first projects since wrapping the fifth and final season of Yellowstone last year. Fans won’t have to wait long to see her back as Beth, though — she’s set to return alongside Cole Hauser in the upcoming spin-off, tentatively titled The Dutton Ranch.
But for now, Under Salt Marsh proves Reilly is more than Beth Dutton. It’s a reminder of her extraordinary range — and a glimpse at the kind of roles that will define her next chapter.
