Agatha Christie Eleven Missing Days brings one of literary history’s most baffling mysteries back into the spotlight, exploring the baffling disappearance that left the world searching for answers.
According to Deadline, two-time Oscar nominee Felicity Jones (The Theory of Everything and Train Dreams) will play the role of legendary suspense thriller writer Agatha Christie. Other cast members include Nicole Elizabeth Berger (He’s Watching You), Oliver Trevena (The Gorge), Ryan McParland (Say Nothing), Alfie Allen (Game of Thrones), Ben Hardy (The Conjuring: Last Rites), and Stacy Martin (The Brutalist).
Bertie Ellwood will be directing from a screenplay by Ernesto Foronda, directly based on the book Agatha Christie and Eleven Missing Days, authored by Christie scholar Jared Cade. Range Select has the US distribution rights. Reports added that Fortitude International introduced the film to the buyers at the Cannes Film Festival.
Producers of the film include Tatiana Kelly from Serena Films, Jim Young from Animus Films, Lucas Jarach from Green Light Pictures, Nadine de Barros from Fortitude International, Joshua Harris from Peachtree Media Partners, and James Cinningham from Object & Animal.
Plot details of Eleven Missing Days
The official synopsis of the film states that in December 1926, Agatha Christie went missing under unknown circumstances from her home. The film is an investigative exploration of her missing case and what led to her mysterious disappearance. Vincent Cassel will play the role of the investigator.
Was anyone involved in the case, or did she herself go somewhere for some time? Her disappearance made national and international headlines and captured public attention, including that of politicians and fellow writers as well. Arthur Conan Doyle was also drawn into the investigation.
Several people speculated that it could be due to a car crash or the result of some kind of trauma and depression, but no clear details have been revealed as of today.
Agatha Christie Eleven Missing Days: Is the new film based on a true story?
Yes, one of the most famous unsolved mysteries in literary history is the real-life story of Christie, nowhere to be found, leaving behind an abandoned car and a few clues about her whereabouts. For nearly two weeks, police officers, volunteers, and every person possible whose help could be used were involved in the search for the celebrated author.
She was later found at a hotel in Yorkshire, where she had checked in under a different name. The reason for her disappearance still remains unknown. Why did Christie not tell the reason for leaving, and what she was doing in the hotel with no contact with anyone?
Christie herself never opened up to what actually happened during those eleven days. The speculations kept rising, giving way to fictional interpretations. The film is the dramatization of those unanswered questions, offering the audience the retelling of one of the most intriguing episodes from real life.

Some historians argue that it could have been possible due to her mother’s recent death and difficulties in her marriage. Others have theories about her likely mental breakdown, leading to an uncurbed desire for some time alone to escape personal pressures.
The film’s appeal remains high as it is related to a mystery story writer becoming one of the mysteries herself. Not only her historical significance but also the enduring uncertainty surrounding the case counts the film among the most-awaited ones.
Certainly, the film could take creative liberties for dramatic purposes; the foundation of the case remains the same. Introducing the story of one of the highly famed authors to the new generation would be world-changing for them, as it would open doors to discovering the woman behind crime mysteries.
Coming from an era when there was no internet and no social media platform to claim viral content, to an era dominated by true-crime documentaries and viral internet mysteries, bringing Christie’s story to the screen would help preserve her legacy, filled with the intrigue of pending questions for the new generation.
