FROM NETFLIX:

There’s nothing more relaxing than a trip on a super yacht — unless you happen to witness a murder. That’s the predicament facing Keira Knightley in The Woman in Cabin 10, a new thriller coming to Netflix Friday October 10, 2025. While on a luxury yacht for a travel assignment, a journalist witnesses a passenger tossed overboard late one night, only to be told that she must have dreamed it, as all passengers are accounted for. Despite not being believed by anyone onboard, she continues to look for answers, putting her own life in danger.

Based on the bestselling novel by Ruth Ware, the film is directed by Simon Stone (The Daughter, The Dig), who also co-wrote the script with Joe Shrapnel and Anna Waterhouse (Snake Eyes: G.I. Joe Origins). Even though the movie’s source material came out 10 years ago, Ware believes it’s still resonant because “the fear of not being believed is perennial, unfortunately, Cabin 10, at its heart, is about a woman who experiences something wrong, reports it truthfully, and isn’t taken seriously because of who she is. Too many people know what that feels like and I think we want vindication for ourselves as much as Lo.”

“I am not imagining this,” Lo Blacklock (Keira Knightley) insists in the trailer for The Woman in Cabin 10. A journalist assigned to cover the story of a luxury superyacht’s first voyage, Lo has just seen a woman fall to her death — but no one believes her. Not Richard Bullmer (Guy Pearce), the superyacht’s wealthy owner, nor her fellow passengers, played by the likes of Kaya Scodelario and Daniel Ings. Nevertheless, as you can see in the trailer below for this adaptation of Ruth Ware’s bestselling novel of the same name, Lo refuses to back down. She’s determined to uncover what happened to this mysterious woman even at the risk of her own life. What was supposed to be a cushy assignment for work turns into a twisty and thrilling excursion on the high seas.

Even though Lo is surrounded by naysayers on the boat, writer and director Simon Stone is adamant that there’s no ambiguity here: Something on this yacht isn’t quite right. “You never question whether or not she saw what she saw, you agree completely with her. It’s her struggle against the conspiracy.” You can get a glimpse at a few of the yacht’s other guests in the trailer. In addition to Pearce’s Bullmer, there’s gossipy Heidi (Hannah Waddingham), influencer Grace (Scodelario), media fortune heir Adam (Ings), and Lo’s photographer ally Ben (David Ajala), to name a few. “It’s an incredibly stacked cast,” Stone says. “Keira has led in an extraordinary way, and Guy as well. But the entire ensemble has been amazing.”

As touchpoints for the film, Stone looked at classic ’70s thrillers like Marathon Man, Klute, The Conversation, and Three Days of the Condor. He also cites the work of Alfred Hitchcock — the Master of Suspense’s film The Lady Vanishes shares a great deal of DNA with Ware’s original novel. “Finding that tradition, but with a different gender and a different energy, has been really exciting,” Stone adds.

The Woman in Cabin 10 stars Knightley, Pearce, Ajala, Art Malik, Gugu Mbatha-Raw, Scodelario, David Morrissey, Ings, Waddingham, Gitte Witt, Christopher Rygh, Pippa-Bennett-Warner, John MacMillan, Paul Kaye, Amanda Collin, and Lisa Loven Kongsli.

Will Lo uncover the answers she’s looking for and make it back to shore alive? You’ll have to watch The Woman in Cabin 10 when it sails onto Netflix on Oct. 10.
