Gillian Anderson’s coastal-trek drama The Salt Path has become entangled in a factual dispute after The Observer alleged major omissions in Raynor Winn’s memoir, the source material for the film.
Investigators claim Winn, legally Sally Walker, once repaid £64,000 to avoid criminal charges over embezzlement—money later secured against the couple’s farmhouse, whose repossession she attributes in the book to a failed investment. Records also show the Walkers retained an unmortgaged property in southwest France during the period they present as homeless.
The book’s medical narrative is under scrutiny as nine neurologists told The Observer that husband Tim “Moth” Walker’s 2013 corticobasal-degeneration diagnosis would not normally allow the apparent recovery depicted.
Winn responded through Substack writer Anna Wharton, insisting the memoir “truthfully recounts a transformative journey” and accusing critics of “weaponising personal hardship.” Publisher Penguin said it is “reviewing new material” but continues to list the title as non-fiction.
The dispute surfaced five weeks after The Salt Path opened on 525 screens, expanding to 603 as word-of-mouth pushed it into the U.K.–Ireland top ten. Box-office services put its global haul at $16 million to date. The Guardian had lauded the film’s rugged cinematography and Anderson’s pared-down turn as Winn. Critics at The Independent noted a “tidy” treatment of homelessness but praised the leads’ chemistry.
Number 9 Films declined comment; a Black Bear marketing representative said the company “stands by the filmmakers” but added that audience trust is “paramount” as the picture prepares for July launches in Australia and North America. Industry analysts warn the row could chill awards momentum yet might equally boost ticket sales by drawing fresh curiosity.
