The Woman in Cabin 10

A Voyage Into Mirrors

There is a particular kind of luxury that feels like a trap. It’s the kind where the thread count of the linens is high enough to suffocate you, and the champagne is so cold it makes your teeth ache. In Simon Stone’s adaptation of Ruth Ware’s *The Woman in Cabin 10*, that trap is literalized on the deck of the *Aurora*, a ship so polished it reflects the moral rot of its inhabitants. I spent most of the film wondering if the boat was moving at all, or if it was just a gilded cage floating in a digital void, waiting for its passenger—a travel journalist named Lo Blacklock—to finally snap.



Simon Stone is a director who loves a crumbling interior, having previously dismantled the bourgeois family unit in *The Dig* and his theater work. Here, he pivots toward something pulpier, leaning into the Hitchcockian trope of the unreliable witness. But where Hitchcock had the luxury of a slow-burn paranoia, Stone feels like he’s fighting against the inherent slickness of the streaming age. The cinematography is crisp—maybe too crisp. Every pane of glass, every polished brass railing on the *Aurora* feels like it’s screaming, "Look at the budget," which occasionally distracts from the claustrophobia Lo is supposed to be feeling. It’s hard to feel trapped when the world looks like a high-end catalogue shoot for a watch brand.

Keira Knightley, playing Lo, is the film's only anchor. She has spent her career mastering a specific kind of internal turmoil—the wide, searching eyes that suggest a mind running three sentences ahead of her mouth. Here, that intensity is weaponized. Watch her in the scenes where she’s interrogated by the ship's security; she doesn’t shrink. She has a way of holding her chin, a slight tremor in her hands as she clutches a wine glass, that tells us she knows she’s being gaslit, even if she can’t prove the reality of the body she saw go overboard.



It’s in the quiet, stuttering interactions between Lo and the ship's enigmatic owner, played by Guy Pearce, where the film actually breathes. Pearce, an actor who has perfected the art of the charming sociopath, plays his scenes with a terrifying stillness. He doesn’t need to raise his voice to make you feel like the walls are closing in. There’s a scene about halfway through—the dinner where the facade begins to crack—that is genuinely unsettling. The camera lingers on Pearce as he cuts a piece of steak, the sound of the knife against the china exaggerated in the mix, turning a simple meal into a surgical procedure. It’s a moment of pure tension, the kind that reminds you why we still bother with the mystery genre in the first place: not for the "whodunit," but for the "can I trust my own senses?"

However, the film struggles to maintain that precision. As the mystery deepens, the plot leans heavily into the melodramatic beats that feel cribbed from airport thrillers. There are moments where the logic of the investigation becomes… flimsy. You have to suspend your disbelief so high you might get altitude sickness. The *Guardian*’s review noted that the film "often mistakes pacing for panic," and there’s truth there. Whenever the story needs to move forward, it sacrifices character consistency for a plot twist. It’s the classic error of the "page-turner" translated to film—what works in a novel when you’re skimming to find out *what happens next* doesn't always translate to the screen, where we are forced to sit and look at the faces of people making terrible, inexplicable decisions.



Ultimately, *The Woman in Cabin 10* is a movie about the cost of being the "hysterical woman." It’s a theme that feels tired, yet Knightley’s performance gives it enough weight to keep the whole thing from drifting out to sea. I wanted more of the psychological disintegration and less of the "cat and mouse" game. I left the theater not thinking about the mystery itself—which, let’s be honest, unravels into a bit of a knot—but about the look on Knightley’s face when she realizes that nobody, not even the people who claim to love her, is actually listening. Maybe the real horror isn't the murder on the boat. It’s the realization that you can be surrounded by a thousand people, all drinking and laughing and dressed in their best, and still be entirely, utterly alone.
