Eleven Missing Days: Felicity Jones Becomes Agatha Christie in 2026's Most Intriguing Thriller
TL;DR: Felicity Jones will play Agatha Christie in the noir mystery-thriller Eleven Missing Days, co-starring Vincent Cassel as a retired Belgian detective. The film dramatizes Christie's real 1926 disappearance and is currently in pre-production, set to shoot in the UK this summer. No streaming platform or release date has been confirmed yet.
Eleven days that stumped an entire nation — and now they're getting the film treatment they deserve
Eleven days. That's how long one of the most famous authors in human history simply vanished from the face of the earth. December 1926. Agatha Christie — already a bestselling name, already the woman who invented Hercule Poirot — walked out of her life and didn't come back for nearly two weeks. No note. No clear explanation. And to this day, no consensus on what actually happened. That gap, that baffling eleven-day void, is the engine powering one of the most compelling film projects announced at the 2026 Cannes market: Eleven Missing Days, a noir mystery-thriller starring two-time Oscar nominee Felicity Jones and César winner Vincent Cassel, with Fortitude International launching the project to buyers this week on the Croisette.
What we know about the film, the cast, and the summer shoot
Confirmed by Deadline on May 11, 2026, Eleven Missing Days is based on Jared Cade's extensively researched book Agatha Christie and the Eleven Missing Days, which has long been considered one of the most thorough accounts of the incident. The screenplay was written by Ernesto Foronda, whose credits include Better Luck Tomorrow, and the film will be directed by Bertie Ellwood, known to television audiences from the Apple TV+ series Silo.
Here's what the production slate looks like right now:
- Lead cast: Felicity Jones as Agatha Christie, Vincent Cassel as a retired Belgian detective, Nicole Elizabeth Berger and Oliver Trevena in supporting roles
- Director: Bertie Ellwood (Silo)
- Writer: Ernesto Foronda (Better Luck Tomorrow)
- Source material: Agatha Christie and the Eleven Missing Days by Jared Cade
- Production status: Pre-production, scheduled to shoot in the UK in summer 2026
- U.S. rights: Represented by Range Media Partners
- Market launch: Cannes 2026, via Fortitude International
The producers are a broad coalition — Tatiana Kelly of Serena Films, Jim Young of Animus Films, Lucas Jarach of Green Light Pictures, Nadine de Barros of Fortitude International, Joshua Harris of Peachtree Media Partners, and James Cunningham of Object & Animal. The project has, notably, been in development for roughly a decade. That kind of slow burn usually signals either a passion project that couldn't get traction, or one that everyone was waiting to get exactly right. Given the casting, it's starting to look like the latter.
Why a decade-old project suddenly feels urgent in 2026
The thing nobody mentions when they talk about Christie adaptations is how thoroughly the market has already mined her fictional work. Kenneth Branagh's Poirot trilogy, BBC's And Then There Were None, The ABC Murders — streaming platforms have been running Christie's plots through their content machines for years. What hasn't been dramatized with this kind of prestige-film weight is Christie herself. The woman, not the detective. The crisis, not the crime.
That's where Eleven Missing Days finds its opening. It's not another Poirot mystery. It's a film about the person who invented Poirot, and what it looks like when her real life starts to resemble one of her own plots — everyone a suspect, no clear motive, a solution that may never fully arrive.
The timing also makes commercial sense. Biopics and real-event thrillers have proven reliable draws across streaming and theatrical: Spencer, Blonde, The Crown, Oppenheimer — audiences have shown consistent appetite for dramatized true stories about iconic figures caught in moments of private collapse. Eleven Missing Days sits comfortably in that lineage. Hard to say if it'll land as a theatrical release or go the premium VOD route, but with Cannes market buzz and this caliber of cast, theatrical seems like the play.
Movie OTT tracks these kinds of prestige acquisitions closely — particularly as international distributors pick up rights out of festival markets and streaming windows get negotiated in the months following. Worth bookmarking.
The synopsis frames Christie's disappearance as a real-life whodunnit — and that's the smart move
According to the official synopsis, the film follows the investigation into Christie's disappearance, treating it structurally as a mystery where "everyone in her life became a suspect" — a framing that's almost poetically on-brand. Cassel's character is described as a retired Belgian police detective drawn into the case. That's an unmistakable nod to Hercule Poirot — Belgian, methodical, retired — without the film being legally or creatively bound to the Christie estate's fictional character.
As noted in coverage at 221B Mag, the film draws from Cade's book, which explored theories ranging from amnesia following a car accident to a dissociative "fugue" state triggered by emotional trauma. Christie's husband Archie had recently asked for a divorce. Her mother had died. The disappearance happened at one of the lowest points of her personal life, which makes the story considerably more complex than a simple publicity stunt — a theory that floated for years.
What's striking is how the film's framing resists the urge to solve the mystery definitively. That's the right call. Any version of this story that lands on a clean answer would feel dishonest.
(Disclosure: Movie OTT reached out to Fortitude International for additional comment on the production timeline; no response was received before publication.)
What the producers have said about bringing Christie's disappearance to screen
The film's synopsis, released through Fortitude International at Cannes, describes the project as "a case of life imitating art" — a whodunnit that "explores the investigation behind her disappearance, strangely resembling an Agatha Christie novel itself where everyone in her life became a suspect."
That's not just marketing copy. It's actually a precise description of what made the 1926 disappearance so culturally electric — the spectacle of a mystery writer becoming the subject of her own genre. Leading politicians mobilized. Arthur Conan Doyle, creator of Sherlock Holmes, was reportedly drawn into the search. Over 1,000 police officers and 15,000 volunteers scoured the English countryside. Christie was eventually found at a hotel in Harrogate, registered under a false name. She never offered a complete public explanation.
Jared Cade's book, reviewed in depth at Savidge Reads, spent years piecing together the most credible account from available evidence. That research forms the backbone of Foronda's screenplay.
How this plays for Indian audiences — and where it might stream
For Indian viewers, this one's squarely in the prestige-international lane. Christie's work has maintained a devoted readership in India for decades — her novels are fixtures in school libraries and railway bookstalls alike — so the built-in name recognition is real. A film about the woman herself, especially one with this level of talent attached, should travel well.
In terms of streaming availability, nothing has been confirmed for Indian platforms as of May 2026. Given the Cannes market launch and the involvement of Fortitude International, the most likely routes would be:
- Netflix India — which has aggressively acquired Cannes market titles and has an existing appetite for British-set prestige content
- Amazon Prime Video India — another active buyer in the international prestige space
- Apple TV+ — particularly relevant given director Bertie Ellwood's Silo connection to the platform
- Theatrical release — possible through PVR Inox or Cinepolis for limited-run prestige programming
Movie OTT's streaming tracker will be updated as Indian distribution rights are confirmed. No Hindi or regional-language dub has been announced, though given the source material's popularity in India, that conversation will likely happen once a distributor is locked.
Jones, Cassel, and Ellwood: what each brings to this project
Felicity Jones earned her first Oscar nomination for The Theory of Everything (2014), playing Jane Hawking opposite Eddie Redmayne's Stephen. She's built a career on exactly this kind of role — real women, documented lives, emotional precision under period-film constraints. Her most recent work in Train Dreams, an acclaimed Paul Dano-directed adaptation, has drawn strong notices. She's the right choice here. Full stop.
Vincent Cassel is one of European cinema's most reliable prestige players. His César win traces back to La Haine (1995), but his range has expanded considerably since — Black Swan, Eastern Promises, Mesrine. He'll next appear in a new installment of HBO's The White Lotus, which keeps him firmly in the prestige television conversation. Playing a Poirot-adjacent Belgian detective is, if anything, a bit of fun for an actor of his caliber.
Bertie Ellwood is the relative newcomer in this trio. Silo gave him a large-scale science-fiction canvas; Eleven Missing Days is a sharper, more intimate proposition. The jump from dystopian Apple TV+ drama to 1920s British noir isn't as strange as it sounds — both require a precise sense of atmosphere and dread. Movie OTT will be watching his approach closely.
What happens next, and when to expect a trailer
With a summer 2026 UK shoot on the schedule, post-production would realistically push a theatrical or festival release into late 2026 at the earliest — more likely early-to-mid 2027. A Venice or Toronto 2026 premiere feels ambitious but not impossible if production moves quickly. A Sundance 2027 slot would make more sense given the timeline.
Range Media Partners is actively selling U.S. rights out of Cannes this week, so a North American distribution announcement could come within weeks. That deal will tell us a lot about whether Eleven Missing Days is headed for wide theatrical or a streaming-first model. For the latest confirmed streaming availability across all regions as announcements land, Movie OTT has the current picture updated in real time.
Keep this one on your radar. It's been a decade in the making — and it's starting to look like the wait was worth it.
