Billie Eilish has undergone a striking mid-century transformation for her feature-film acting debut in The Bell Jar. Newly released photographs from the Toronto set show the Grammy and Oscar-winning musician dressed as Esther Greenwood, the ambitious young writer at the centre of Sylvia Plath’s influential 1963 novel.
The first-look images replace Eilish’s familiar oversized silhouettes and contemporary styling with carefully structured 1950s clothing, pearl jewellery, red lipstick and neatly arranged brown hair. The visual change is dramatic, but it also offers the first meaningful indication of how director Sarah Polley intends to translate Plath’s psychologically complex story to the screen.
According to People’s first look at The Bell Jar set, production is underway in Toronto, with Eilish filming exterior scenes surrounded by performers dressed in similarly period-appropriate clothing.
Eilish’s 1950s Makeover Introduces Esther Greenwood
In one group of photographs, Eilish wears a scarlet short-sleeved knit top with a checked A-line skirt, pearl earrings and a strong red lip. Her shoulder-length brown hair is styled with a controlled side part that immediately places the character within the conservative visual world of the early 1950s.
Other set images reportedly show Eilish wearing a modest blue dress layered over a pink skirt. The clothes appear intentionally conventional, reflecting the polished expectations placed on young women during the period rather than the provocative or exaggerated appearance often used for celebrity transformations.
Vogue’s examination of Eilish’s Bell Jar costume notes how sharply the fitted knitwear, pearls and structured skirt contrast with the loose streetwear and boxy suits frequently associated with her public image.
That contrast has made the photographs immediately attention-grabbing. However, the styling is more than a celebrity makeover. Esther begins the novel as an academically successful young woman entering a glamorous professional environment while privately struggling with identity, ambition and worsening psychological distress. The neat exterior therefore carries narrative significance because it conceals the growing disorder Esther experiences internally.
The Set Photos Appear to Capture Esther’s New York Period
The Bell Jar follows Esther after she receives an opportunity to work at a women’s magazine in New York. The experience should represent professional achievement, but she becomes increasingly disconnected from the glamorous life surrounding her.
The Toronto street scenes appear designed to reproduce this early-1950s New York environment. Eilish is shown among groups of formally dressed women, with the production using costumes and street details to create the tightly controlled social world Esther encounters during her magazine assignment.
The precise scene being filmed has not been officially identified. Still, the costumes suggest that the adaptation will give significant attention to the contradiction between the attractive professional opportunities available to Esther and the restrictive expectations attached to them. The novel examines a world in which an intelligent young woman is encouraged to succeed while simultaneously being directed toward a narrow version of marriage, femininity and acceptable ambition.
Eilish’s transformation captures that contradiction visually. She appears composed, appropriately dressed and capable of belonging within the environment, but readers familiar with the novel know that Esther’s sense of control is already beginning to weaken.
‘The Bell Jar’ Marks Billie Eilish’s First Feature-Film Role
The adaptation represents a substantial career change for Eilish. Although she has appeared in music videos, documentaries and concert films, The Bell Jar will be her first acting role in a feature-length narrative film.
Her most significant previous dramatic performance came in Donald Glover and Janine Nabers’ series Swarm. Eilish played Eva, the quietly unsettling leader of a women’s group, in a performance that demonstrated she could create tension through stillness and controlled speech rather than relying on her identity as a musician.
Eilish is also a two-time Academy Award winner for songs created with her brother Finneas. The pair won for the James Bond theme “No Time to Die” and the Barbie song “What Was I Made For?” Her movement into a demanding literary adaptation therefore extends an existing connection with cinema while placing her under an entirely different kind of scrutiny.
The role of Esther will require more than recreating the character’s period appearance. Much of the novel’s impact comes from Esther’s internal voice, including her sharp observations, dark humour, detachment and inability to understand why a life that appears successful feels increasingly impossible to inhabit.
Translating that perspective into a screen performance will be one of the film’s defining challenges.
Sarah Polley Makes the Casting More Intriguing
Eilish’s casting might have appeared like a risky celebrity-led decision under a less experienced filmmaker. The involvement of Sarah Polley gives the project considerably greater dramatic credibility.
Polley is adapting the screenplay and directing the film, which will be her first feature as a director since Women Talking. That film earned her the Academy Award for Best Adapted Screenplay and examined women attempting to make life-changing decisions within a restrictive community.
Her work has frequently focused on memory, trauma, female autonomy and the difficulty of expressing private experiences. Those interests make her a logical filmmaker for a story in which the protagonist’s public identity and inner reality become increasingly separated.
Variety’s report on the project identifies Focus Features as the studio, with Plan B Entertainment, Studiocanal and Joy Coalition involved in producing the adaptation.
Polley’s presence also suggests that the film is unlikely to reduce Esther’s experience to a visually attractive period drama or a simplified story of celebrity breakdown. The novel’s humour, anger and criticism of gender expectations are as essential as its depiction of mental illness.
Carey Mulligan Will Play Esther’s Mother
The supporting cast is also beginning to take shape. Carey Mulligan has joined the production as Mrs. Greenwood, Esther’s mother.
Mrs. Greenwood has a difficult role within the story. She wants her daughter to become practical and independent, but she often struggles to understand the seriousness of Esther’s condition. Their relationship combines affection, misunderstanding, frustration and the wider generational expectations placed on women.
Mulligan’s casting gives the adaptation another performer experienced in emotionally restrained period dramas. Her previous work in films including An Education, Suffragette, Promising Young Woman and Maestro has regularly involved characters negotiating social pressure and private dissatisfaction.
Variety confirmed Mulligan’s reported role while noting that Connor Storrie has also been associated with the developing ensemble. Further character details have not been formally announced.
Adapting Sylvia Plath Requires Considerable Care
The Bell Jar was Sylvia Plath’s only novel. It was originally published under the name Victoria Lucas and drew partly from her experiences as a young writer, including a magazine placement in New York and treatment for severe depression.
The story is frequently described as semi-autobiographical, but Esther should not be treated as a direct documentary representation of Plath. She is a fictional character shaped through satire, symbolism and carefully constructed narration.
The Academy of American Poets’ biography of Sylvia Plath identifies The Bell Jar as one of the writer’s central works and notes its original publication under a pseudonym. The Poetry Foundation’s Plath archive also places the novel within a wider body of writing concerned with identity, artistic ambition and psychological experience.
Any modern adaptation must portray Esther’s mental-health crisis without turning suffering into a fashionable aesthetic. The novel contains painful material involving depression, suicidal thoughts and psychiatric treatment, but it is also observant, socially critical and frequently darkly funny.
The first photographs cannot reveal how successfully Polley and Eilish will manage that balance. They show only the visible surface of a story built around the instability beneath visible surfaces.
The Transformation Creates Interest, but the Performance Will Decide Everything
Eilish’s appearance as Esther is convincing enough to generate immediate curiosity. The period styling separates her from her stage identity and allows the audience to begin seeing a character rather than a pop star playing dress-up.
That is an encouraging beginning, not proof that the performance will work. Esther Greenwood is a demanding role because the character often withdraws rather than explaining herself openly. Her emotional decline must become understandable without being made theatrical merely for the camera.
Eilish’s controlled performance in Swarm suggested an ability to communicate unease with relatively little dialogue. Polley’s direction may provide the structure needed to expand that ability across a full-length film.
No official release date has been announced. Filming began in Toronto during the summer of 2026, meaning audiences may have to wait before seeing footage or a trailer.
For now, the set photographs have achieved their purpose. They reveal a complete visual departure for Eilish, establish the film’s mid-century atmosphere and suggest that the adaptation is treating Esther’s external world with careful attention.
The greater transformation will have to occur onscreen. Eilish must make audiences forget the famous musician beneath the pearls and red lipstick and believe in Esther Greenwood as a brilliant young woman struggling to breathe beneath the expectations surrounding her.
