The Woman in Cabin 10 Cast: Full List of Actors and Characters

Mystery fans know the feeling: you’ve finished the book, cleared the evening, and now you’re about to watch a favorite thriller get a very different life on screen. The Woman in Cabin 10 landed on Netflix on October 10, 2025, with Keira Knightley in the lead and a supporting roster that reads like a casting director’s dream. Here’s who plays whom, how the film drifted from Ruth Ware’s novel, and whether the ensemble rescues a bumpy voyage.

Release date: October 10, 2025 · Director: Simon Stone · Starring: Keira Knightley, Guy Pearce, David Ajala, Gugu Mbatha-Raw · Based on: The Woman in Cabin 10 by Ruth Ware · Runtime: 1 h 32 min · Genre: Mystery thriller

Nine rows, one pattern: this is a compact Netflix original built on a proven book title and a heavyweight cast — not a sprawling franchise movie.

Who are the main cast members of The Woman in Cabin 10?

Every adaptation lives or dies by casting, and this one leans hard on its ensemble. The four leads carry the film’s emotional weight, while a dozen supporting names give the yacht its texture.

The four leads

• Keira Knightley as Laura “Lo” Blacklock — the film’s protagonist
• Guy Pearce as Richard Bullmer — the wealthy owner of the yacht
• David Ajala as Ben Morgan
• Gugu Mbatha-Raw as Rowan

The four roles are confirmed by JustWatch’s credit list, and Netflix’s own title-page billing puts Knightley, Pearce, and Hannah Waddingham at the top of the cast list.

Knightley’s Lo is the engine of the film: a journalist whose working voyage turns into a nightmare when a scream comes from the cabin next door. It’s the kind of interior role she has built a career on, and it holds the film together even when the plot starts to drift.

The supporting ensemble

• Hannah Waddingham as Heidi Heatherley
• Art Malik as Dr. Robert Mehta
• Kaya Scodelario as Grace Phillips
• David Morrissey as Thomas Heatherley
• Daniel Ings as Adam Sutherland
• Gitte Witt as Carrie
• Christopher Rygh as Lars Jensen
• Pippa Bennett-Warner as Karla
• John Macmillan as Captain Addis
• Paul Kaye as Danny Tyler
• Amanda Collin as Sigrid Nilssen
• Lisa Loven Kongsli as Anne Bullmer

The full roster above comes from JustWatch’s credit list, which mirrors the film’s official credits carried on major streaming databases.

The faces below the title

• Charles Craddock as First Officer Hewitt
• Ayọ̀ Owóyẹmi-Peters as Izzy, a stewardess
• Síofra Ní Éilí as Orla, a stewardess
• Holly Godliman as Eva, the spa therapist

Metacritic’s credit list adds these names and pushes the named ensemble to 20 roles.

Is The Woman in Cabin 10 based on a true story and why is it different from the book?

No — the film is not a true story. It’s a fictional thriller adapted from Ruth Ware’s novel of the same name, and that distinction matters because the marketing leans into the same claustrophobic realism that made the book a word-of-mouth phenomenon.

Why people keep asking if it’s real

• The film is a fictional novel adaptation, not a true-crime story
• The closed-circle setup — a small luxury yacht in the middle of the sea — creates a locked-room mood that feels uncomfortably plausible
• True-crime fans often find thriller fiction with realistic procedures harder to clock as invented

Six comparison points, one pattern: the movie keeps the novel’s premise and reshuffles the reveal.

Book vs film — where the adaptation shifts

What this means: the film treats Ware’s book as a springboard, not a script. If you know the novel, you’ll recognize the skeleton — but the muscle and the final blow have been rearranged for a streaming audience that wants answers in under 100 minutes.

The pattern: the film uses the novel’s premise but rewrites the resolution, which is why both book fans and newcomers should watch with an open mind.

Where was The Woman in Cabin 10 filmed and was it on a real yacht?

Production specifics for the film are thin in the public record, and the verified sources behind this guide don’t include a detailed location breakdown. What’s been reported points in one direction: the Mediterranean.

Filming locations

• The production reportedly used Malta as its primary filming base
• Mediterranean exteriors give the yacht sequences their bright, isolated look
• Interior cabin scenes were reportedly built on sound stages for the control that night-time thriller coverage requires

The location claims above come from production reporting rather than Netflix’s official materials, so treat them as directional rather than confirmed.

Real yacht or sound stage

• Exterior and deck footage used a real vessel, with the story’s ship named the Aurora
• The claustrophobic cabin interiors were built as sets, which is standard for maritime thrillers that need repeated night coverage

The catch: the practical split between real boat and built sets matters mostly to production nerds and travelers looking for the Aurora’s real-world twin. Netflix hasn’t published an official location note for this title in the materials reviewed, so the honest answer is that the details are partly unconfirmed.

The practical answer to the original question: yes to a real vessel for the drama above deck; yes to a set for the cabin claustrophobia. Either way, the Aurora does its job — it makes you feel like there’s nowhere to run.

Why did The Woman in Cabin 10 get bad reviews and is it worth watching?

The short answer: it hasn’t been a critics’ darling, and the reasons keep circling back to two words — pacing and deviation. The longer answer is more interesting, because the cast is exactly why many viewers are willing to forgive both.

What critics keep saying

• Critical response has been mixed to negative in early roundups, with the cast frequently praised
• Pacing and the degree of deviation from Ruth Ware’s novel are the two recurring complaints
• The review conversation is tracked by Metacritic’s roundup for the film
• The verified sources behind this guide didn’t include a stable Rotten Tomatoes critic score at the time of writing

The audience counterpoint

• Early audience ratings have run slightly higher than critic scores
• Viewers with no attachment to the book tend to respond more positively to the streamlined plot
• The cast — Knightley and Pearce in particular — is the most-cited reason to watch

The catch: the film’s streamlined pace and altered plot may disappoint purists, but for viewers who prioritize performances, Knightley and Pearce deliver.

What is the twist and who is the killer in The Woman in Cabin 10?

This is the part where we do our job and still protect your watch. The film is new, the spoiler-sensitive window is real, and the verified details about the ending are structural rather than name-specific. So: the mechanics, without the who.

The twist, explained without spoilers

• The reveal is built around a case of mistaken identity
• The film’s answer to “who is the killer?” lands on a character the audience is led to trust
• The murderer’s identity reportedly differs from the novel’s, which is the adaptation’s boldest single decision

Spoiler-free summary of how it plays out

• A journalist on a small yacht believes a woman in the next cabin is in danger, and most of the people around her insist nothing happened
• The resolution pulls the mystery back to the yacht owner’s circle, where every passenger turns out to be connected

What this means for thriller fans: the movie is playing a trust game with you. It asks you to bet on the wrong character on purpose, then quietly moves the cards.

Who is the owner of the yacht in The Woman in Cabin 10?

The vessel belongs to Richard Bullmer, and he’s played by Guy Pearce — which tells you how much weight the role carries.

Richard Bullmer, played by Guy Pearce

• Richard Bullmer owns the yacht and hosts the voyage that turns into a mystery
• His wife, Anne Bullmer, is on the passenger list — played by Lisa Loven Kongsli

Both pairings appear in the same credit lists confirmed above: Pearce as Bullmer, Kongsli as Anne Bullmer.

His role in the story

• Bullmer’s presence creates the closed circle on board: guests, crew, and captain all revolve around him
• His character is central to the plot’s resolution, and Pearce’s performance gives the reveal its weight

The pattern: the owner is the story’s gravity well. Everyone on that yacht is connected to Bullmer one way or another, which is exactly why the twist keeps circling back to his cabin and his marriage.

Each of the film’s key data sources tells the same story from a different angle: the cast is confirmed, the roster is deep, and the reception is split.

Keira Knightley, Guy Pearce, and Hannah Waddingham are the names at the top of the cast billing — the clearest signal of who Netflix is selling this thriller on.

Review aggregators are tracking a mixed conversation around the film — a strong cast working inside a plot that struggles to match Ruth Ware’s novel.

— Metacritic (review aggregator), review roundup context

The Woman in Cabin 10 is the rare Netflix thriller where the conversation right now is less about the plot and more about the player list. The cast — Knightley, Pearce, Waddingham, and a 20-name roster around them — is the reason to watch, and the 92-minute run makes the commitment painless. For book purists, expectations should be managed: this is a re-telling, not a translation, and the ending walks its own road. For Netflix, the equation is already settled: Knightley and the cast get the film talked about even when the reviews waver.
