Keira Knightley dazzles at The Woman in Cabin 10 premiere with floral gown and lace ruff

Keira Knightley exuded elegance on Thursday night as she greeted her co-star Hannah Waddingham at the premiere of The Woman in Cabin 10 at BAFTA Piccadilly. The 40-year-old actress arrived in a vintage-inspired olive-green gown that was embroidered with flowers, beaded and finished with sparkling diamond details. Belting the waist with two brown leather straps, Knightley added a quirky lace ruff at the neck and completed the look with black lace-up boots and makeup that highlighted her refined, classic glamour on the red carpet.

Hannah Waddingham, 51, matched the evening’s glamour in a plunging denim dress that showcased her figure, featuring black beaded details on the pockets. The duo shared a warm hug as they posed for photographers, with Waddingham also exchanging a smile and a moment with co-star Guy Pearce. Pearce appeared in a velvet tuxedo jacket paired with navy trousers and a white T‑shirt, while Daniel Ings joined in a smart black blazer over a collared shirt and grey tailored trousers. Norwegian actress Gitte Witt brought contemporary glamour in a fashion-forward take on the little black dress, with off-the-shoulder styling and dramatic sleeves. David Ajala added a bold touch in a royal blue jacket with canvas trim and matching trousers.

Keira Knightley stars as travel journalist Laura “Lo” Blacklock in Netflix’s The Woman in Cabin 10, due for release in October. The psychological thriller is adapted from Ruth Ware’s 2016 novel and follows Laura as she goes on a travel assignment aboard a luxury yacht. Late one night she witnesses a passenger being tossed overboard, but is told she must have dreamt the incident as all passengers are accounted for. The film builds on a premise of doubt and danger that keeps viewers questioning what really happened on board.

In addition to Knightley and Waddingham, the premiere highlighted a star-studded cast that also includes Kaya Scodelario, Art Malik, David Morrissey, Paul Kaye and John Macmillan. The ensemble’s presence underscored the high profile nature of Netflix’s thriller as it gears up for an autumn release. The production has drawn attention for its adaptation of Ware’s novel and for the performances of a cast described by producers and readers alike as bringing depth to a claustrophobic, suspenseful setting.

Ruth Ware spoke to Tudum about the enduring relevance of Cabin 10 a decade after first writing the suspenseful story. She noted that the fear of not being believed remains perennial, and she praised the film’s cast and crew for bringing Lo and her world to life. “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,” Ware said. “Too many people know what that feels like and I think we want vindication for ourselves as much as Lo.” She emphasized the collaborative effort behind adapting the book for the screen, saying it takes a village to realize a story on film.

As the premiere and the ensuing promotional circuit unfold, Netflix fans and thriller audiences alike will be watching to see how Cabin 10 translates to the screen and whether the film can deliver the tense, unraveling mystery that Ware’s novel laid out. The red-carpet moment at BAFTA Piccadilly offered a stylish preview of the tone and mood the movie aims to deliver, with Knightley’s refined look and Waddingham’s bold styling signaling a confident start to the film’s rollout.
