Billie Eilish is stepping into a completely new creative era. The Grammy- and Oscar-winning musician has been photographed in costume for the first time on the Toronto set of The Bell Jar, marking her feature film acting debut.
Eilish will play Esther Greenwood, the ambitious young writer at the centre of Sylvia Plath’s celebrated 1963 novel. Directed and adapted by Academy Award winner Sarah Polley, the film explores identity, ambition, mental health and the pressures placed on women navigating rigid social expectations.
A striking 1950s transformation
The first set images reveal a dramatic visual departure from the oversized silhouettes and dark colour palettes long associated with Eilish’s public image.
For the role, the singer appears with auburn-brown hair styled in a polished mid-century look, bright red lipstick and pearl earrings. One outfit combines a red pointelle sweater with a checkered pleated skirt, matching T-strap heels and a coordinated handbag.
Other photographs show Eilish walking through streets recreated to resemble 1950s New York, surrounded by women in colourful period clothing. In another scene, she is drenched by rain while wearing a vintage green shirtwaist dress layered over a pale patterned skirt and simple dark flats.
The transformation immediately positions costume as an important part of the film’s storytelling. Esther’s carefully constructed exterior reflects the polished expectations surrounding young women of the era, while the story itself gradually reveals the emotional conflict beneath that surface.
Billie Eilish enters Sylvia Plath’s world
First published in 1963, The Bell Jar follows Esther after she earns a prestigious magazine internship in New York City. What initially appears to be an exciting step towards the life she imagined soon gives way to disillusionment and an increasingly severe mental health crisis.
The semi-autobiographical novel became one of the most influential literary works about female identity, creative ambition and psychological isolation. Its themes of feminism, conformity and emotional pressure remain deeply relevant more than six decades later.
Casting Eilish brings an intriguing contemporary dimension to the role. Much of her music has explored vulnerability, anxiety, fame, isolation and the tension between public identity and private experience — themes that closely echo Esther Greenwood’s inner world.
A major cast joins the adaptation
Eilish will be joined by Carey Mulligan, who plays Esther’s mother, Mrs. Greenwood. The cast also includes Connor Storrie in a role that has not yet been disclosed.
The project marks Sarah Polley’s first feature as a director since Women Talking, which earned her the Academy Award for Best Adapted Screenplay. Focus Features is backing and distributing the film, with production having begun in Toronto in late June 2026.
For Polley, whose work frequently centres on women’s interior lives, memory and social power, Sylvia Plath’s novel feels like a natural continuation of her cinematic interests.
From music to cinema
Although The Bell Jar is Eilish’s first feature acting role, it is not her first experience on screen. She previously appeared in the 2023 series Swarm, where her performance offered an early glimpse of her ability to create a quietly unsettling character.
Her connection to cinema is already substantial. Alongside her brother and longtime collaborator Finneas, Eilish has won two Academy Awards for the songs “No Time to Die” and “What Was I Made For?” from Barbie. Her concert documentary Billie Eilish: Hit Me Hard and Soft also brought her creative world to the big screen.
This time, however, she is not performing as herself. She is entering one of modern literature’s most emotionally demanding roles, leaving behind the visual identity audiences know and stepping fully into another woman’s world.
The Bell Jar does not yet have an official release date, with filming expected to continue in Toronto throughout summer 2026. Still, the first images already suggest that Billie Eilish’s transition from global music star to dramatic actress may become one of the most closely watched screen transformations of the year.
