The 5 Best Mystery Movies Released in 2026 So Far

Did you grow up solving “Clue” — or “Cluedo,” depending on where you live — and trying to identify the killer before anyone else? Maybe Nancy Drew and the Hardy Boys were constant companions, or perhaps you have an uncanny knack for spotting the culprit in every murder mystery you watch. Either way, you’ve come to the right place: this is our guide to the best mystery movies of 2026 so far.

This year’s lineup takes a wonderfully unconventional approach to the genre. (Rian Johnson’s “Wake Up Dead Man: A Knives Out Mystery,” the third entry in his acclaimed series of elegant, delightfully convoluted whodunits, premiered in late 2025 and therefore doesn’t qualify.) The movies below include an alien thriller that examines humanity, a feverish tale involving a pop star and a dressmaker, and a murder investigation conducted by sheep. There are also, rather notably, several films starring Anne Hathaway — 2026 may well be her year. One final note: the titles appear in alphabetical order rather than by rank, and we’ll continue updating this list as the year’s best mysteries arrive. With that in mind, here are 2026’s standout mystery movies so far.

Steven Spielberg’s hugely entertaining and surprisingly thoughtful summer spectacle, “Disclosure Day,” opens with cybersecurity whistleblower Dr. Daniel Kellner (Josh O’Connor) barely escaping a pursuit led by technology executive Noah Scanlon (Colin Firth). Alongside his girlfriend, Jane Blankenship (Eve Hewson), Daniel steals a device that appears to hold enormous importance. At first, his story seems unrelated to that of Margaret Fairchild (Emily Blunt), an on-air meteorologist at an NBC affiliate in Kansas City. Then Margaret begins suffering bizarre symptoms. During a live broadcast, she speaks in clicks and other incomprehensible sounds before collapsing. Later, while hospitalized with her boyfriend Jackson (Wyatt Russell), she escapes just before agents from Scanlon’s ominous company, Wardex, can abduct her while posing as FBI officials.

Margaret and Daniel eventually discover that they are central figures in a sweeping conspiracy created by the U.S. government and Wardex to conceal proof of extraterrestrial life. The cover-up goes far beyond hiding aliens from the public: both organizations have also subjected them to decades of physical abuse. As the pair races to expose — or “disclose” — the existence of alien life, they uncover startling truths about themselves and the parts they have played in this vast mystery. “Disclosure Day” works as a carefully constructed sci-fi thriller, revealing its secrets piece by piece, while also serving as a dark examination of human nature and our seemingly limitless willingness to destroy whatever stands in our way.

David Robert Mitchell, the filmmaker behind the inventive horror hit “It Follows,” was always likely to deliver an unusual mystery. What makes “The End of Oak Street” such a surprise is that this latest puzzle arrives in the form of a dinosaur-filled summer blockbuster. Mitchell’s gloriously strange story follows the Platt family: Greg (Ewan McGregor), Denise (Anne Hathaway), Audrey (Maisy Stella), Brian (Christian Convery), and their dog, Starbuck. The family is already under strain, with Greg and Denise’s conflict becoming increasingly obvious to their children. Greg is working as a pizza delivery driver after losing his job, while Denise secretly dreams of becoming a successful novelist. Their lives are troubled but recognizable — until a bizarre storm transforms the neighborhood into a prehistoric jungle packed with ravenous, deadly dinosaurs.

The film’s advertising did little to prepare audiences for just how grisly “The End of Oak Street” becomes. Beneath the mountains of blood and gore, however, lies a genuine mystery that both the Platts and viewers must piece together. Even after the final credits, several questions remain deliberately unresolved. That lingering uncertainty is part of the film’s appeal, leaving you to ponder how the impossible events actually unfolded long after you’ve left the theater.

Na Hong-jin’s “Hope” arrived at the Cannes Film Festival to near-universal praise, quickly establishing itself as one of 2026’s essential thrillers. Na wrote and directed the film, bringing together a remarkably international ensemble. South Korean stars Hwang Jung-min, Zo In-sung, and Jung Ho-yeon appear alongside Michael Fassbender, Taylor Russell, Cameron Britton, and Alicia Vikander. But what exactly is “Hope,” and what makes it stand out in an especially strong year for thrillers?

At its core, “Hope” is a monster movie. Ko Bum-seok (Hwang), the police chief of Hope Harbor — a community near the demilitarized zone separating North and South Korea — becomes alarmed when cows begin turning up dead under increasingly strange conditions. He fears that the isolated town, whose residents are largely elderly, is facing a much greater threat. His concerns prove justified when an exceptionally powerful creature unleashes terror across Hope Harbor. The film piles on twist after twist, sometimes to the point of overwhelming the viewer, but that disorientation appears intentional. By the time Na brings his startling, wholly original mystery to its terrifying conclusion, “Hope” leaves you rattled in the best possible way.

With genre-defying films such as “The Green Knight,” “The Old Man and the Gun,” and “A Ghost Story” on his résumé, David Lowery has become one of independent cinema’s most compelling directors. His 2026 release, “Mother Mary,” further confirms that reputation. Anne Hathaway plays the titular pop superstar, who is attempting a major comeback with an enormous performance after an onstage incident damaged her career. Dissatisfied with the costumes available to her, Mary seeks out an old friend for a custom design. That friend is Sam Anselm (Michaela Coel), a reclusive designer with a deeply complicated history with Mary: the two were once lovers.

“Mother Mary” refuses to settle into a single category. It is a psychosexual drama about estranged former partners who still care for each other, a story of artistic transformation and reinvention, and a horror thriller in which ghosts embody the distance separating them. It is also a gripping mystery, powered by the electric performances of Hathaway and Coel. Both actors are magnetic, and together they help make Lowery’s ambitious film one of 2026’s finest genre-bending mysteries.

“The Sheep Detectives” ranks among 2026’s best mysteries — and, quite possibly, among the year’s best films in any genre. Directed by Kyle Balda and written, surprisingly, by “Chernobyl” and “The Last of Us” showrunner Craig Mazin, the movie stars Hugh Jackman as George Hardy, a shepherd living in a remote cabin outside the quiet English village of Denbrook. Each night, George reads murder mysteries to his devoted flock. What he doesn’t realize is that the sheep understand every word. They also adore George, whose kindness and generosity make his sudden death on the property all the more devastating.

Lily (voiced by Julia Louis-Dreyfus) assumes command of the flock and draws on the herd’s extensive knowledge of detective fiction to identify George’s killer. She is joined by Sebastian (Bryan Cranston), Cloud (Regina Hall), Mopple (Chris O’Dowd), and Zora (Bella Ramsey), among others. The human cast also features Nicholas Galitzine, Nicholas Braun, Molly Gordon, Hong Chau, and the legendary Emma Thompson. Beneath its playful premise, “The Sheep Detectives” delivers a surprisingly moving story about grief: the sheep must uncover the truth about George’s death while learning what death itself means. The result is warm, funny, and unexpectedly profound. If you haven’t seen it yet, this delightful mystery deserves to be your next watch.
