Production is officially in the can on one of the most intriguing literary adaptations in years. Focus Features has confirmed that filming has wrapped on The Bell Jar, Academy Award winner Sarah Polley's adaptation of Sylvia Plath's landmark novel, with Billie Eilish starring as Esther Greenwood in her feature film acting debut.
The shoot, which began June 29, 2026, in Toronto — standing in for 1950s New York — ran through early September, with the wrap announced on September 8 alongside a full cast confirmation. Produced by Plan B Entertainment, STUDIOCANAL, and Joy Coalition, and directed by Polley from her own adapted screenplay, the film has no theatrical release date yet — but it has already become one of the most closely watched productions on the awards-season horizon.
Eilish's leap to leading lady
For Eilish, a two-time Academy Award-winning singer-songwriter (for her contributions to the Barbie and No Time to Die soundtracks), the role of Esther Greenwood is a genuine career pivot: her first leading role in a feature film. She has acted before — a memorable turn in the 2023 Prime Video series Swarm — and appeared as herself on Sesame Street, hosted Saturday Night Live in 2021, and this summer starred in and co-directed (with James Cameron) the 3-D concert film HIT ME HARD AND SOFT: THE TOUR (LIVE IN 3D). But carrying a prestige literary adaptation is a different order of magnitude.
Set photos released in early August showed Eilish in 1950s-style costumes and hairstyles on the Toronto set, and the images traveled widely — an early sign of the cultural attention the film is likely to command. Esther Greenwood, the brilliant young writer whose magazine-internship summer in New York spirals into a confrontation with mental illness amid the suffocating expectations placed on women in 1950s America, is one of the great roles in twentieth-century literature. It is also a role that has defeated filmmakers for decades.
Polley's return behind the camera
If Eilish is the headline, Polley is the reason to take the project seriously. The Oscar winner directs from her own adapted screenplay — her first feature as a director since winning the Academy Award for Best Adapted Screenplay in 2023 for Women Talking. Polley has built a career on intimate, morally serious films about women under pressure, and Plath's semi-autobiographical novel — published in 1963, remaining continuously in print and selling millions of copies worldwide — sits squarely in her territory.
The material's history explains why this adaptation matters. Plath's only novel was previously brought to the screen in 1979, and subsequent attempts — including versions that would have starred Julia Stiles and Dakota Fanning, with Kirsten Dunst at one point set to direct — collapsed in development. That Polley's version actually reached the finish line of principal photography is, by the standards of this particular book, an achievement in itself.
An ensemble built for prestige
The confirmed cast reads like a festival programmer's wish list. Carey Mulligan, whose casting was first reported by Variety in July, plays Esther's mother, Mrs. Greenwood. Danielle Deadwyler plays Dr. Nolan, Esther's psychiatrist; Dylan Hawco plays Buddy Willard, Esther's first boyfriend; Lili Taylor plays Jay Cee, the editor of Ladies' Day magazine; Ella Beatty plays Joan, an old acquaintance who ends up at the same mental hospital as Esther; and Maggie Kuntz plays Doreen, Esther's best friend in New York and a fellow intern.
Rounding out the ensemble: Ike Barinholtz as Lenny, a wealthy New York radio host, and Connor Storrie — the breakout of the hockey-themed series Heated Rivalry — as Marco, the character the novel remembers for a violent encounter at a dance. Storrie's casting had been rumored since July, when a Canadian museum posted about his presence at a filming location, before Focus Features confirmed it with the wrap announcement.
Why the timing matters
Literary adaptations of this ambition level are increasingly rare in a marketplace dominated by franchises — which is precisely why The Bell Jar stands out on the 2027 calendar. Focus Features has a strong track record of shepherding exactly this kind of film through awards season, and the combination of Polley's authorship, Eilish's cultural gravity, and a heavyweight ensemble gives the distributor multiple paths to audiences: prestige cinemagoers, Plath's generations of readers, and Eilish's global fanbase.
The film now enters post-production, and the next milestones to watch are a festival premiere — a slot at Cannes, Venice, or Telluride would be the traditional launchpad — and the announcement of a release date. Given the pedigree involved, expect both to be treated as events. Plath's novel has waited more than sixty years for a definitive screen version. If Polley and Eilish have delivered one, the wait will have been worth it.
A novel that resisted the screen
Plath's novel has one of the most tortured adaptation histories in literature. Published in the UK in 1963 — a month before the author's death — and in the US in 1971, The Bell Jar became a defining text of twentieth-century literature, remaining continuously in print and selling millions of copies. Yet the screen resisted it: a 1979 film version came and went, and every subsequent attempt stalled. Kirsten Dunst spent years developing a version with Dakota Fanning attached to star, at one point planning to direct it herself, before the project fell apart. That context makes the Toronto shoot something of a small miracle: for most of the summer, the city stood in for 1950s New York, with filming running from June 29 through early September and set photos of Eilish in period costume drawing wide attention in August. For a book that has defeated filmmakers for over sixty years, simply reaching the end of principal photography is the story — everything from here is upside.
