A tense trailer that teases paranoia, danger, and disbelief.

Intrigued by the way thrillers turn the ordinary into the uncanny, I was immediately drawn to the trailer for The Woman in Cabin 10.

Netflix’s psychological drama casts Keira Knightley as Lo, a travel journalist whose dream trip on a luxury yacht unravels when she claims to witness a murder. The crew insists nothing happened, but the trailer makes it clear: Lo refuses to be silenced. Streaming begins 10 October.

Gaslighting on the High Seas

The set-up is simple yet unnerving: a witness no one believes and a woman determined to prove her sanity. Knightley leans into the paranoia, repeating "It was real."

Around her is a strong supporting cast — Guy Pearce, Hannah Waddingham, Gugu Mbatha-Raw among others — adding weight to the mystery. Haven’t we all known what it’s like not to be taken seriously?

Behind the Curtain

Director Simon Stone adapts Ruth Ware’s bestselling novel with Joe Shrapnel and Anna Waterhouse. Ware herself notes the story is about women not being believed — a theme that resonates today.

With producers Debra Hayward and Ilda Diffley and Netflix backing it, The Woman in Cabin 10 could be more than just a glossy thriller. It might even mark Knightley’s sharpest role in years.
