Keira Knightley’s Netflix thriller turns dream cruise into deadly mystery

Netflix has unveiled new images and an official release date for The Woman in Cabin 10, a psychological mystery thriller starring Keira Knightley that transforms a luxury cruise into a claustrophobic nightmare. Based on Ruth Ware’s bestselling novel, the film lands on Netflix October 10 and with its high-stakes paranoia and star-studded cast, it’s already one of the platform’s most anticipated thrillers this fall.

Knightley plays Lo, a travel journalist assigned to cover a boutique cruise in the North Sea. But when she witnesses a woman being thrown overboard in the middle of the night, her reporting instincts kick in. There’s just one problem: no one else onboard believes her. According to the ship’s manifest, no one is missing. Gaslit and isolated, Lo launches her own investigation, risking her credibility, and safety, to find the truth.

Netflix’s new stills offer a tense glimpse at the slow unravelling of Lo’s mental state, as well as key characters aboard the ship. The cast includes David Ajala, Guy Pearce, Hannah Waddingham, David Morrissey, and Gugu Mbatha-Raw, each of whom may be hiding something beneath their polished surface.

Directed by Simon Stone, known for his emotionally layered films The Dig and The Daughter, the movie is expected to focus as much on internal dread as external danger. Co-written with Joe Shrapnel and Anna Waterhouse, the script adapts the novel’s themes of disbelief and female isolation in closed spaces, a fear that author Ruth Ware says still feels relevant today.

Ware noted, “Cabin 10 is about a woman who reports the truth and isn’t taken seriously because of who she is. Too many people know what that feels like.”

The trailer is still under wraps, but with its mix of glamour, mystery, and psychological tension, The Woman in Cabin 10 promises a slow-burn thriller that lingers.
