Keira Knightley shimmers in floral olive gown as The Woman in Cabin 10 premiere brings star power to BAFTA Piccadilly

Keira Knightley was the picture of sophistication on Thursday night as she shared a delighted embrace with co-star Hannah Waddingham at the premiere of their Netflix thriller, The Woman in Cabin 10, at BAFTA Piccadilly. Knightley, 40, wore a vintage-inspired olive-green gown richly embroidered with flowers, with beading and diamond accents. She cinched the waist with two brown leather belts and added a quirky lace ruff at the neck, finishing the look with black lace-up boots and understated, radiant makeup.

Hannah Waddingham, 51, arrived in a plunging denim dress that emphasized her curves, featuring a corseted silhouette and black beaded details on the pockets. The Ted Lasso star posed with Knightley, sharing a warm hug as photographers captured the moment. Other attendees included Guy Pearce in a velvet tuxedo jacket and navy trousers, Daniel Ings in a sharp black blazer with gray tailored pants, and Norwegian actress Gitte Witt in a modern little-black-dress variant with voluminous sleeves. Keira Knightley stars as travel journalist Laura "Lo" Blacklock in The Woman in Cabin 10, which is due for release in October. The psychological thriller is adapted from Ruth Ware’s 2016 best-selling novel and follows Laura on a voyage aboard a luxury yacht after she witnesses a passenger being tossed overboard, only to be told she must have dreamed it because all passengers are accounted for.

The star-studded cast also includes Kaya Scodelario, Art Malik, David Morrissey, Paul Kaye and John Macmillan. Waddingham appears as Heidi, with Daniel Ings in the role of Adam, Gitte Witt as Carrie and David Ajala as Ben. The film’s ensemble also features remarks from Ruth Ware about the adaptation’s resonance a decade after the book’s publication. Ware told Tudum that the fear of not being believed remains a universal experience and praised the on-set collaboration, saying that while the story is hers, it required a village to bring it 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," she said, adding that she was heartened by the cast and crew and the sense that the characters were "in good hands."

Ware’s reflections underscore a broader appreciation for the adaptation’s ensemble and the producers’ commitment to staying true to the source material while delivering a tense, contemporary thriller. The film, shot across a stylish luxury yacht setting, is poised to join Netflix’s October lineup as audiences anticipate a modern twist on the classic locked-room mystery. The premiere at BAFTA Piccadilly offered a high-gloss backdrop for the movie’s release ahead of its formal debut on streaming, with Knightley and Waddingham among the most photographed on the night.}
