Eleven Missing Days is an upcoming British biographical mystery thriller film. Starring Felicity Jones and Vincent Cassel, the film delivers a fictionalised account of Agatha Christie's real-life eleven-day disappearance in December 1926.
When crime writer Agatha Christie (Jones) goes missing, members of her family and household fall under suspicion. The investigation falls to a retired Belgian detective (Cassel) who happens to resemble Christie's famed character Hercule Poirot.
The film was announced in May 2026, with Fortitude International shopping the project to buyers at the Cannes market.
In June, Oliver Trevena was cast as Agatha Christie's brother. Further cast were unveiled later on June 8, with filming commencing later that week. Haywards Heath was touted as a potential filming location, with London also included.
Filming wrapped in July.
