Keira Knightley has always had a knack for making neurosis look elegant. In Netflix’s upcoming The Woman in Cabin 10, she takes that talent and wraps it in a fog of paranoia so thick you’d swear the subtitles should come with a flashlight. But behind every trembling teacup and half-lit stare lies a curious inspiration, a little something borrowed from a certain 1974 Warren Beatty quirk.

Only Knightley could turn a Beatty tic into a psychological weapon, proving once again that madness, in the right hands, can be an art form, preferably framed in Netflix’s moody grayscale.

Keira Knightley is working on a thriller project, The Woman in Cabin 10, in which she plays Laura Blacklock, a journalist who witnesses a murder on a luxury yacht that no one believes actually occurred. To prepare for the role, director Simon Stone encouraged her to watch classic 1970s paranoia thrillers, including films starring Gene Hackman, Warren Beatty, and Robert Redford, as per Variety. This influence likely shaped her performance, bringing a sense of calm tension reminiscent of those iconic films, especially The Parallax View. In essence, Knightley did not exactly copy Warren Beatty’s quirk but used it as a starting point to craft her own unique performance.

According to Variety, Keira Knightley adapted her acting style for The Woman in Cabin 10 by taking inspiration from 1970s thriller stars, including Warren Beatty’s calm and measured performance in The Parallax View. Director Simon Stone encouraged Knightley to move beyond mere imitation, instead finding a nuanced and intense portrayal for her character, Laura Blacklock. This approach enabled Knightley to convey a sense of paranoia and tension in the role while maintaining a calm exterior.

The movie’s plot is as captivating as the acting transformation of Keira Knightley, viewers have just explored.

The Woman in Cabin 10 centers on Lo Blacklock, a struggling journalist assigned to cover the maiden voyage of a luxurious cruise ship in the frigid North Sea. Her professional opportunity quickly devolves into a nightmare when she witnesses what she believes is a body being thrown overboard from the neighboring cabin. The critical problem arises when a headcount confirms every passenger and crew member is accounted for, making her the sole, highly unreliable witness.

Laura Blacklock’s (Keira Knightley) persistent investigation into the vanishing woman is complicated by her own emotional fragility and the cruise ship’s confined, claustrophobic environment. As she struggles to prove the murder was real, the people around her begin to question her sanity, suggesting her mind is playing tricks on her. This setup creates a deeply unsettling psychological thriller in which the protagonist must fight for the truth while simultaneously struggling to maintain her own grasp on reality.
