Trevena's casting represents a major career milestone, positioning him alongside Oscar-nominated talent like Jones while he steps into the shoes of one of history's most fascinating real-life figures in Monty Collins Christie.
Sources close to production hint that Trevena's rapid-fire slate of films—spanning action with Liam Neeson and prestige projects with Harvey Keitel—isn't coincidence. The Rome Film Festival Breakout Actor award apparently opened doors faster than anyone expected.
The film is based on Jared Cade's book 'Agatha Christie and the Eleven Missing Days' and will shoot summer 2026 in the U.K., with Bertie Ellwood directing from Ernesto Foronda's screenplay. Trevena was honored at Rome Film Festival by Gerard Butler.
Christie's disappearance has all the makings of a classic whodunnit—and now someone's actually making it one. With Trevena's recent awards buzz and this stacked cast, 'Eleven Missing Days' might be the project's trajectory from festival curiosity to awards contender.
Oliver Trevena is stepping into one of history's most deliciously mysterious roles: Monty Christie, brother to the Queen of Crime herself. The "Plane" and "The Bricklayer" actor has officially joined Felicity Jones and Vincent Cassel in "Eleven Missing Days," a noir mystery-thriller that tells the unsettling true story of Agatha Christie's 11-day disappearance in 1926. Bertie Ellwood is directing from a screenplay by Ernesto Foronda, adapted from Christie scholar Jared Cade's book "Agatha Christie and the Eleven Missing Days." The film puts Jones at center stage as she portrays the legendary author during the period when she vanished from her home under bizarre circumstances—becoming front-page news across Britain.
Trevena will play Monty, Christie's brother who, in a delicious irony befitting this project, becomes one of the suspects in his own sister's disappearance. The timing couldn't be more interesting for Trevena, whose career has been on an undeniable upswing. He was recently honored by the Rome Film Festival with a Breakout Actor award, presented personally by "Plane" co-star Gerard Butler at the premiere of action-thriller "The Paradox Effect." That film stars him opposite Harvey Keitel and Olga Kurylenko—talent that doesn't typically share screen space with emerging actors.
He also produced and starred alongside Kurylenko in "Misdirection," demonstrating he's building a portfolio beyond just acting credits. His recent filmography reads like a who's-who of established A-listers: "Hotel Tehran" with Liam Neeson and Zachary Levi, TIFF selection "The Cut" opposite Orlando Bloom, "Mermaid" with Mel Gibson, the comedy "Skinemax" alongside Rory Culkin and Paris Jackson, and "Ice Fall" with Joel Kinnaman—a project where he also served as executive producer.
The breadth of these connections suggests Trevena has positioned himself as someone studios trust with high-profile collaborations. Currently in pre-production with U.K. filming scheduled for summer 2026, Range Select is handling U.S. rights distribution. For Christie fans who've long speculated about those eleven missing days—whether she was hiding from her husband's affair, suffering a breakdown, or something darker—the film promises to explore every uncomfortable corner of her life and marriage.
With Cassel in the cast as well, this isn't just a literary biopic; it's a potential powder keg of secrets, suspicion, and scandal that would make Miss Marple proud. Repped by Untitled Entertainment, Independent Talent Group, and law firm Rosenfeld, Meyer & Susman, Trevena's casting here represents his most high-profile role yet—placing him directly in the orbit of Oscar-nominated talent while he inhabits a character whose real-life counterpart spent nearly two weeks as Britain's most wanted woman.
