5 Must-Watch Mystery Movies of the 21st Century, Ranked

Few film genres are as endlessly inviting as mystery. From classic whodunnits to more unconventional puzzles, mysteries have been a cinematic staple for generations, and the 21st century has delivered its share of outstanding entries. Here, we’re ranking five of the best mystery movies released since 2000.

Of course, the boundaries between mystery, thriller, crime drama, and related genres can be difficult to define. For this ranking, the mystery must be central to the story — the characters and audience should be focused primarily on identifying a culprit or decoding a complicated chain of events. Films such as “Oldboy” and “Fight Club” may contain powerful mysteries, but they ultimately belong more firmly to other genres.

The list of honorable mentions is extensive, though Kenneth Branagh’s recent Hercule Poirot films deserve particular recognition. Each one combines drama, eccentricity, and ensemble appeal, and while none quite made the final ranking, they helped bring the traditional murder mystery back into the mainstream. Interestingly, the five films selected here come from just three directors, with two filmmakers appearing more than once.

With those guidelines in place, let’s begin the countdown.

Few filmmakers have done more to revive the classic whodunnit in the 21st century than Rian Johnson, and his 2022 mystery sequel “Glass Onion” is only one example of his contribution. Following the enormous success of 2019’s “Knives Out,” the Netflix film once again features Daniel Craig as the irresistibly eccentric detective Benoit Blanc. This time, Blanc travels to the private island of tech billionaire Miles Bron (Edward Norton), where an elaborate murder mystery weekend takes a deadly turn.

Although “Glass Onion” did not generate quite the same cultural phenomenon as its predecessor, it displays the same confident command of the genre. Its characters draw from familiar whodunnit archetypes while also serving as sharp targets for the film’s commentary on wealth, privilege, and modern society. The result is a mystery that remains colorful, witty, and full of surprises, with Janelle Monáe delivering one of the movie’s standout performances.

Johnson has now gone three for three with his “Knives Out” mystery films, all of which deserve a place among the genre’s finest modern examples. Still, the original has a slight edge over “Glass Onion” — more on that soon.

David Fincher is widely regarded as one of contemporary cinema’s defining thriller directors. While many of his films lean toward crime, horror, or psychological suspense rather than traditional mystery, he has repeatedly demonstrated a remarkable command of the form. “Gone Girl” is a prime example: a sleek, unsettling story of resentment, desire, and emotional cruelty built around an absorbing disappearance case.

When Amy Dunne (Rosamund Pike) vanishes, public suspicion quickly turns toward her husband, Nick (Ben Affleck). The investigation exposes a maze of deceit, infidelity, and manipulation, suggesting that both sides of the marriage may be hiding something. Through a shifting timeline, the film gradually reveals new perspectives on the couple’s past and the circumstances surrounding Amy’s disappearance.

Nonlinear storytelling was hardly new to mystery cinema when “Gone Girl” arrived in 2014, but Fincher executes it with such precision and polish that the structure feels freshly powerful. Rosamund Pike’s ferocious performance is equally essential, establishing her as a major star. Among the films on this list, “Gone Girl” places the least emphasis on the mystery itself, yet that mystery provides the perfect lens through which to examine a deeply disturbing relationship. At its core, the film is about marriage, resentment, and the lengths people may go to hurt someone they once claimed to love — making it one of the most memorable mystery movies of the last 26 years.

The second David Fincher film on this list takes the bronze medal, despite being one of the director’s most underappreciated works. “Zodiac” is not discussed as often as “Fight Club” or “Se7en,” and it earned less at the box office than “Gone Girl.” Released in 2007, the film also received no Oscar nominations, reportedly in part because of its late arrival during awards season. Given its acclaimed cast — including Jake Gyllenhaal, Robert Downey Jr., Mark Ruffalo, and Brian Cox — and Fincher’s reputation, that Academy shutout remains difficult to explain.

Inspired by the real Zodiac Killer investigation, “Zodiac” was built on extensive research. Fincher, screenwriter James Vanderbilt, and the production team studied police files and re-interviewed people connected to the original murders. The film presents the case with painstaking detail while also exploring the psychological toll it takes on investigators, journalists, and law enforcement. Most importantly, “Zodiac” embraces an ambiguous conclusion that reflects the unresolved nature of the real case — and of countless mysteries throughout history.

One could argue that “Zodiac” is the greatest mystery film ever made because it is ultimately less interested in solving one particular case than in examining what happens when a mystery may never be solved. That idea is more philosophical than the traditional “the butler did it” formula, but third place feels like a fitting compromise.

For anyone seeking a classic murder mystery with a modern sensibility, it is difficult to top “Knives Out.” Impeccably paced, cleverly constructed, and filled with memorable performances, Rian Johnson’s film is a near-perfect example of the contemporary whodunnit. Daniel Craig’s first appearance as Benoit Blanc played a major role in moving him beyond his James Bond image, while Ana de Armas gives a deeply affecting performance as Marta Cabrera. The ensemble is just as impressive, with sharp turns from Jamie Lee Curtis, Chris Evans, and Michael Shannon, among others.

What makes “Knives Out” especially effective is its ability to celebrate the genre without turning into a parody. The film is self-aware but never dismissive, functioning as both a love letter to classic mysteries and a clever reinvention of their familiar conventions. Without spoiling the experience, Johnson’s decision to reveal the answer early and then surround it with twist after twist is one of the movie’s great pleasures. Numerous small details also gain new significance on repeat viewings, adding to the satisfaction of this exceptionally entertaining ensemble mystery.

Beyond its elegant narrative machinery, the film has plenty to say about class and cash as they pertain to the social order — a theme that would continue to resonate through the “Knives Out” sequels. For the most traditional mystery viewers, this could have easily held the number-one spot, but we went with something a bit older for the gold medal.

It feels blasphemous to say, given his modern superstardom, but Christopher Nolan may well have made his greatest film in 2000. “Memento” is the ultimate mystery movie. The film itself is a mystery the audience must uncover, about a character trying to solve a mystery as he struggles against a mental condition that turns every moment of his life into its own small mystery. Psychologically, it’s a story about the gnawing sensation of leaving something unsolved, as well as the often insufficient satisfaction of finally finding the answer. By the end of “Memento,” the mystery itself evolves into something different entirely.

So many of the cinematic signatures that would become Nolan’s calling cards are here: the nonlinear narrative, black-and-white sections, the repetition of language and scene, the long-con sub plot, and so on. And those all work pretty well in his later, bigger films, but they are especially affecting here, in a film with essentially three characters, shot in three or four locations.

The limitations are the strength of “Memento.” Guy Pearce is a powerhouse as Leonard, a man so traumatized by the murder of his wife that his brain has ceased to form new memories, forcing him to tattoo the clues of his murder investigation on his own skin in order to find the killer. Carrie-Anne Moss and Joe Pantoliano are similarly excellent in the two main supporting roles, and Nolan smashes this small handful of players together in the most interesting of ways, making a mystery film that’s both riveting on the first watch and incredible on every subsequent visit.
