After memorably portraying some of television’s most unsavoury characters—Timothy Ratliff in The White Lotus and Lucius Malfoy in the Harry Potter series—British actor Jason Isaacs has taken on a decidedly gentler role in The Salt Path. Based on the 2018 memoir by Raynor Winn, the film follows a real-life couple who lose their home and business, then embark on a 1,000-kilometre trek along England’s South West Coast Path. In his first “good guy” turn, Isaacs stars as Moth Winn, a man confronting homelessness and a devastating medical diagnosis with courage, compassion—and, surprisingly, humour.
From Villain to Virtuous Hiker
“I didn’t know if the audience would accept it,” Isaacs admits of his casting as one half of a devoted couple. Having built a reputation as a menacing presence on screen, he found it “a challenge to play a nice guy.” Yet the script’s blend of adversity and hope, paired with Isaacs’s rapport with co-star Gillian Anderson, made the leap irresistible. To capture the authenticity of his character, Isaacs spent hours in video calls with the real Michael “Moth” Winn. “He was so generous,” Isaacs recalls. “Even describing the darkest moments—feeling suicidal, ashamed of letting his family down—he’d find a way to make me laugh.” This openness helped Isaacs internalize the unseen struggles behind Moth’s ever-present optimism.
Plot Synopsis: Love, Loss, and the Long Walk
Raynor (Anderson) and Moth Winn lose their farm and savings to a failed investment. Shortly thereafter, Moth experiences debilitating shoulder pain. Initial suspicions of arthritis give way to a grim diagnosis: corticobasal degeneration (CBD), a progressive neurological disease. In defiance of destitution, the couple decide to walk the South West Coast Path—an arduous 1,000 km trail stretching from Minehead in Somerset to Poole in Dorset. Penniless, they wild-camp in a tattered tent, subsisting on pot noodles and fudge bars. Yet, amid freezing nights and constant hunger, they rediscover resilience: “One of the characters in this film is…this extraordinary coastline,” Isaacs says. “It was a huge part of their recovery.”
Themes of Homelessness and Human Kindness
As Ray and Moth travel, not everyone greets them with kindness. “When people saw middle-class folk wandering, they’d think, ‘How lovely,’” Isaacs explains. “But when they learned they were homeless, some recoiled or even hurled abuse.” The film highlights society’s ambivalence toward those without homes, reminding audiences that homelessness can strike anyone. Yet compassion prevails in unexpected moments. Locals offer spare beds, food, or simple conversation, underscoring “the choices available to us: to be generous or to slam our doors,” Isaacs notes. This duality—cruelty and kindness side by side—deepens the narrative beyond a mere survival trek.
A Portrait of Enduring Love
Isaacs calls Ray and Moth “madly in love.” Having shared over three decades of marriage and raised two children, they finish each other’s sentences and care for one another in equal measure. When Moth’s body betrays him, Ray lifts him from bed, tends his personal needs, and walks alongside him on rugged cliffs—a testament to devotion rarely portrayed so tenderly on film. Beneath Moth’s cheerful exterior lies profound fear. Isaacs reveals that, in real life, Winn contemplated ending his suffering: “He hid that from Ray. She didn’t know he was suicidal because he spent every day trying to cheer her up.” This poignant contradiction—private despair masked by public cheer—drives Isaacs’s nuanced performance.
Contrasting with Timothy Ratliff
Isaacs draws a clear distinction between Moth and Ratliff, his brittle White Lotus persona. “Tim couldn’t bear humiliation; he spent his life feeling superior,” the actor explains. “Moth, by contrast, never felt better than anyone else. Even with nothing left, he shared what little he had.” This comparison underlines Isaacs’s fascination with “unpacking human behavior” and underscores his versatility.
Behind the Camera: A Theatre Director’s Film Debut
Based on her acclaimed theatre work—including War Horse and The Curious Incident of the Dog in the Night-Time—director Marianne Elliott makes her feature debut with The Salt Path. To navigate challenging locations, she enlisted veteran cinematographer Hélène Louvart. Filming rugged coastlines presented logistical hurdles. Louvart deployed remote camera rigs, allowing the crew to shoot multi-angle sequences from safe distances. “We felt alone on the hillside,” Isaacs recalls. “We didn’t know where the frame ended. That isolation helped us fully embody Ray and Moth’s experience of being cut off from the world.”
The Actor’s Journey: Physical and Emotional Demands
Isaacs admits the production was gruelling: “Sleeting rain, freezing cold…we felt very sorry for ourselves at times.” Unlike Hollywood sets offering creature comforts, the cast endured sodden tents and heavy sleeping bags, a reality mirrored in their characters’ nightly struggles.
Eschewing a traditional three-act arc, The Salt Path unfolds as a chronicle of real events. “It’s a journal,” Isaacs says, “where scenes simply follow what happened, significant or not.” This unconventional storytelling demands that audiences invest in the minutiae of everyday hardship, creating a raw, lived-in authenticity.
Conclusion
In portraying Moth Winn, Jason Isaacs has not only expanded his dramatic range but also illuminated a story of love, resilience, and social empathy. The Salt Path invites viewers to reconsider their assumptions about homelessness, to marvel at the healing power of nature, and to witness a marriage tested by loss and illness yet strengthened by shared adversity. As Isaacs and Anderson guide us along the windswept cliffs and hidden coves of England’s southwest coast, they deliver a film that is at once intimate, unflinching, and ultimately triumphant—a true story made all the more extraordinary by the humanity at its heart.
