William Smith is a flesh and blood writer who hasn't seen natural sunlight in months. He spends every waking hour at his laptop producing content to satisfy the cruel algorithm and to give those who spend their time in the comments section something to criticize.

Who doesn't love a mystery movie? They engage audiences and ask them to become participants in their plots, doling out clues so they can attempt to solve them alongside the protagonist. Even a bad mystery movie can be mildly diverting for an afternoon's worth of entertainment. The great mystery movies, the ones with perfect mysteries, are one of the most enthralling and enticing forms of cinema. Whether they're true crime thrillers, like Zodiac, or comedic whodunits, like Clue, they offer audiences a more interactive entertainment experience.

There are plenty of popular mystery movies, classics of the genre that have been praised up and down and continually listed among the best, but there are also many truly perfect ones that audiences have forgotten. These are the mystery crime thrillers whose cases have gone cold and the slick sleuth protagonists that have slipped through the system. These perfect mystery movies encompass everything from neo-noir, hacker heists, road thrillers and even cosmic horror. Despite their differences, they all share in plots filled with twists and turnabouts to keep audiences guessing along the way. No two mysteries are the same in any of these films, and they all have different approaches to how they solve them and protagonists that are at varied levels of eccentric and cynical. The only mystery these perfectly puzzling movies share is why they've all been forgotten.

'Sneakers' (1992)

The main cast stands outside in a line looking concerned in Sneakers — River Phoenix, Dan Aykroyd, Sidney Poitier, Robert Redford, & David Strathairn standing in line & looking confused in Sneakers

Sneakers is a perfect little crime caper comedy with lots of mystery elements within its then-modern hacker plot. It was generally well-reviewed when it was released, but most treated it as light entertainment. If only critics knew how good they had it back then, they might have been kinder to the film, since most now would kill for something as effortlessly entertaining and breezy, with a cast half as good. This movie is stacked top to bottom with talent. Led by Robert Redford, the cast includes fellow screen legend Sidney Poitier, consummate character actor David Strathairn, comedy icon Dan Aykroyd, the often underutilized Mary McDonnell, Oscar-winner Ben Kingsley, and the gone-too-soon River Phoenix in one of his last film appearances. Behind the camera is Phil Alden Robinson, directing from a script co-written by acclaimed producer Walter F. Parkes. It's also got an incredible score by the late James Horner to punctuate its perfect popcorn entertainment value.

Redford leads a team of hackers and security specialists, all of whom have checkered pasts. They are approached by the NSA to steal a mysterious black box from a mathematician in exchange for having their records wiped clean, but after the success of their heist, they find themselves knee-deep in government conspiracies and criminal activities. The cast is having an absolute ball with the material, with none of them phoning it in, even though they could all perform their roles in their sleep. Sneakers comes from an era where explosive action scenes weren't a prerequisite for every tentpole movie, and it manages to be just as entertaining as any bombastic blockbuster with simple scenes of its characters sorting through garbage. It's a classic caper with more than enough mystery in its plot to keep the intrigue high while hanging out with its characters.

'Devil in a Blue Dress' (1995)

Don Cheadle and Denzel Washington as Mouse and Easy in Devil In A Blue Dress

Devil in a Blue Dress is a stylish neo-noir directed by the underrated Carl Franklin and starring Denzel Washington in another commanding lead performance as Easy Rawlins. The character comes from a series of crime novels by Walter Mosley, and in a just world, audiences would've gotten a series of film adaptations of these starring Washington. It's set apart from its crime contemporaries by the mere presence of a Black protagonist, but the significance of that is more than just skin-deep, as the film is steeped in the racial politics of its post-World War II Los Angeles setting. In addition to Washington, the film has stand-out supporting performances from Jennifer Beals, Tom Sizemore, and especially Don Cheadle as a trigger-happy associate of Easy's. Devil in a Blue Dress belongs right alongside the other neo-noir mystery classics of the '90s, like L.A. Confidential.

As Rawlins, Washington is approached by Sizemore's slimy private investigator to help track down a missing woman. Like any good noir, it doesn't take long for the investigation to take some dark twists and turns, with Rawlins getting implicated in a murder and uncovering some very dark secrets involving a political candidate. It's appropriately sordid and stylized, and the mysteries are fundamentally connected to racial identity and societal prejudice. Whether that makes the plot more resonant to some viewers than others has no bearing on how effective the other pulp elements of it are. Devil in a Blue Dress is an immaculately crafted crime thriller, with Washington giving one of his most underrated lead performances and Cheadle stealing scenes as he did in every '90s film he appeared in. It's an essential neo-noir that deserves far more recognition.

'Breakdown' (1997)

Most road thrillers are more concerned with taut suspense scenes than with tangled webs of mystery. Movies like Duel, The Hitcher, and Road Games are all effective at ratcheting up the tension, but their greatest mysteries are mostly relegated to the identities of their homicidal antagonists. The perfectly paced action-thriller Breakdown, however, adds a layer of mystery to its plot proceedings in its terrific first act. The movie quickly unravels its conspiracy so that it can get to the proverbial white-knuckle suspense, and it gets a lot of mileage out of its early moments of mystery. It also benefits from a terrific lead performance by Kurt Russell, who is equally adept at playing an everyman who is out of his depth as he is an unhinged madman pushed to the absolute edge of reason.

Russell plays a man traveling cross-country with his wife, played by Kathleen Quinlan, when their car breaks down in the Arizona desert. The wife hitches a ride with a kindly truck driver (J.T. Walsh) to a nearby diner to call a tow truck. When the wife never returns with said tow-truck, Russell tracks down the truck driver, who insists he never saw him or his wife before. It's a nightmare scenario for any spouse, and while the movie isn't interested in a Twilight Zone-esque breakdown of reality, the mystery gives it just enough fuel before it turns into a lean, mean thrill ride. Director Jonathan Mostow would go on to more middling efforts like U-571 and Terminator 3: Rise of the Machines, but Breakdown is still a perfect mystery thriller.

'Brick' (2005)

Writer-director Rian Johnson is best known now for his Benoit Blanc mystery films in the Knives Out franchise, but his career kicked off with an equally eclectic mystery thriller. Brick has all the hardboiled hallmarks of a noir detective story, from its pulpy plot to its punchy dialogue, but with a unique approach to the genre due to its high school setting. As with all of Johnson's filmography, Brick subverts its genre expectations while fully embracing them. While its premise could very easily devolve into cheap parody or an empty gimmick, Johnson's script finds fresh avenues of the genre to explore and cleverly mixes archetypes from both noir and teen movies together. It's also got a wicked mystery that would make Dashiell Hammett proud.

Joseph Gordon-Levitt, in a key performance that helped him graduate from teen roles to more mature fare, plays high school student Brendan, whose ex-girlfriend Emily (Emilie de Ravin) dies under mysterious circumstances. Brendan then plunges himself into investigating her murder, and finds himself deep in an underworld of drugs and teenage angst. Brick features everything that Johnson has become known for. It breaks genre expectations and even the expectations of what one might expect from the film itself, given its unusual premise. It was a bold calling card for the director and is still one of the most refreshingly original mystery movies of the 21st century.

'Resolution' (2012)

Two men sitting on the floor in Resolution — Chris Daniels (Vinny Curran) sits handcuffed on a mattress with a despondent demeanour while his friend Michael Danube (Peter Cilella) sits opposite him in a dingy shack in 'Resolution' (2012).

Justin Benson and Aaron Moorhead have contributed some of the most intriguing genre films of the last couple of decades. Their films, The Endless, Spring and Synchronic, are all idiosyncratic and filled with more ideas than some entire studio's yearly output. Those films all share a loose continuity together that also includes their otherwise forgotten first feature, Resolution. It's small-scale but has big ideas, which help it transcend its low-budget trappings. Combining character drama with thriller and cosmic horror elements, the film is also endlessly mysterious, with a plot that twists in directions so unexpected it's near-impossible to know where it will lead next.

The film begins with Michael (Peter Cilella) visiting his friend Chris (Vinny Curran) at a remote cabin. Chris suffers from substance abuse, and Michael is intent on getting him clean by any means necessary. He handcuffs Chris in an effort to sober him up, but it soon becomes apparent that the men have greater threats to contend with. In addition to violent criminals and cultists, some unseen entity is also stalking the surrounding woods, and what it hungers for, they don't know. Like so many low-budget horror films before it, Resolution makes up for its budgetary limits with smart writing and ingenuity. Benson and Moorhead operate on a wavelength all their own, and for those who haven't discovered their filmography, there's no better place to start than this magnificent mystery movie.

'The Kid Detective' (2020)

Released during the COVID era, it's no mystery as to why The Kid Detective is basically nonexistent in the cultural conscience. That's a damn shame because it's a clever mystery movie of surprising darkness and depth, and one of the absolute best of the 2020s. Despite its deceptively cute title and the fact that it was inspired by children's mystery novels like Encyclopedia Brown, the film has a genuinely unsettling mystery and a flawed but compelling protagonist. Adam Brody has scarcely been better than he is here, managing to perfectly balance the film's darkly comedic tone with its underlying tragedy.

Brody plays Abe Applebaum, a former child detective haunted in his adulthood by the disappearance of his childhood friend, who was never found. Now a struggling private investigator with substance abuse issues, Abe sees a chance at redemption when he's approached by a high schooler who asks for his help to solve the murder of her boyfriend. The investigation is hampered by Abe's comically amateurish tactics, but he also uncovers dark secrets with deep roots. The only thing more surprising than the resolution to the film's mystery is the unexpected emotional territory it charts. The Kid Detective hasn't gotten half the praise it deserves, and just like the secrets central to its plot, it deserves to be rediscovered.
