Published Aug 14, 2026, 10:58 PM EDT Ryan Heffernan is a Senior Writer at Collider. Storytelling has been one of his interests since an early age, with his appreciation for film and television becoming a particular interest of his during his teenage years. This passion saw Ryan graduate from the University of Canberra in 2020 with an Honours Degree in Film Production. In the years since, he has found freelance work as a videographer and editor in the Canberra region while also becoming entrenched in the city's film-making community. In addition to cinema and writing, Ryan's other major interest is sport, with him having a particular love for Australian Rules football, Formula 1, and cricket. He also has casual interests in reading, gaming, and history. The 21st century has been a golden age for horror cinema. From the flurry of experimental low-budget movies of the early 2000s, many of which were inspired by the execution and performance of The Blair Witch Project, to the more socially-minded and cerebral pictures the genre has seen in the past decade, the modern era has been a triumphant time for scary movies and those who adore them. Even with such an extensive list, several noteworthy titles have had to be omitted, from cultural phenomena like Saw and Paranormal Activity to ensnaring cult gems like Talk to Me and The Mist. The movies that do make the cut illuminate not only the utter brilliance of the genre over the past 26 years, but the intense variety of styles, tones, and narrative ideas as well, with everything from subversive supernatural chillers to probing psychological horrors featuring. 25 'The Substance' (2024) Image via Mubi Becoming something of a social media sensation upon release, The Substance combines brutal body horror with timely thematic resonance to be one of the defining movies of the 2020s. Powered by two outstanding lead performances from Demi Moore and Margaret Qualley, it follows a fading actress who injects herself with a serum that promises to restore her to her former glory only to find herself trapped in a waking nightmare when things go horribly wrong. The film gained immediate recognition for how it offers commentary on the superficiality of entertainment culture, the absurd nature of beauty standards imposed on starlets, and even the cultural unease we seem to have with aging naturally. Skewering these ideas with obscene and stomach-churning imagery, The Substance finds an invigorating balance between body horror brutality and dark comic satire that is wickedly enjoyable and visually shocking. 24 'Lake Mungo' (2008) Image via Arclight Films. Australian horror has enjoyed something of a golden era throughout the early part of the 21st century, with everything from Wolf Creek’s slashing violence to Talk to Me’s ghostly intrigue making an impression around the world. However, it is the fiendishly terrifying low-budget gem Luke Mungo that has come to be heralded by many as being the nation’s most impressive and haunting exploit in recent years. An ingenious spin on the found-footage phenomenon of 00’s horror, it unfolds in the aftermath of a young woman’s drowning. As her family struggle to make sense of the strange instances that plague them, they begin to question whether Alice (Talia Zucker) is really gone and pry into her final months, thus revealing a dark secret and a nightmarish supernatural encounter. Powered by the tragic emotional core of the family dynamic and a handful of scenes that make the blood run cold, Lake Mungo is a true cult gem of modern horror. 23 'The Others' (2001) Image via Warner Bros The Others is a forgotten gem of early 2000s horror. Defying the contemporary trend of outright visual terror, it runs more as a classical horror story, an elegant and tightly-plotted descent into haunted house horror that revolves around Grace Stewart’s (Nicole Kidman) relocation with her kids to a remote country house in mid-40s England where she becomes increasingly certain that the place holds malevolent supernatural entities. Alejandro Amenábar’s deft direction leans on old-school horror techniques, using candlelit eeriness and isolation to create an unnerving atmosphere of pressing psychological tension. In lieu of jump scares and special effects, The Others uses precise screenwriting and Kidman’s powerhouse performance as tools to construct horror. Complimented by an unforgettable conclusion, The Others is a stunning display of horror cinema at its most reserved, controlled, and unsettling. 22 'The Cabin in the Woods' (2014) Image via Lionsgate Horror fans have always loved a great send-up of genre conventions, a fun-loving spoof that dissects the machinations of the form while finding subversive ways to deliver some thrills of its own. The Cabin in the Woods has been the best example of this in the 21st century so far, with the cult classic horror-comedy expanding the premise of college kids encountering demonic evil in a remote cabin into a brilliantly conceived satire that is smart, funny, and sharply attuned to genre formalities. Able to toy with clichés while delving into the minutiae of horror cinema, The Cabin in the Woods excels by going far beyond simple scares. While there are a few genuine jolts to be had, the film finds its ethos in its abundance of plot twists, satirical brilliance, and its rich array of enjoyable characters, from the playful parody of caricatures the five college kids embody, to Richard Jenkins' and Bradley Whitford's wickedly delightful mad scientists. 21 'Under the Skin' (2013) Image via A24 Challenging, enigmatic, and strangely human, Under the Skin leans heavily into surrealism as it combines cold and creeping sci-fi with the haunting atmosphere of horror. Featuring a bold and commanding performance by Scarlet Johansson, it transpires in Scotland as a mysterious alien roams the streets, seducing lonely men so she can lure them to a black liquid abyss in which they are decomposed. Director Jonathan Glazer implements several unorthodox methods throughout the film to elevate the predatory nature of the horror with a palpable, voyeuristic unease, including the use of hidden cameras and casting non-actors. However, Under the Skin is no simple alien invasion movie wherein humanity is the victim. Instead, it uses its premise to dissect complex issues of isolation, superficiality in beauty, sexual objectification, and—through Johansson’s stunning work—how hostile, indifferent iciness can shift to empathy and compassion. 20 'A Tale of Two Sisters' (2003) Image Via Cineclick Asia A relentless psychological horror from South Korea that combines ferocious family drama with the piercing terror of a well-executed ghost story, A Tale of Two Sisters is a viciously twisty highpoint of Asian horror in recent decades. Inspired by the Joseon era “Janghwa Hongryeon jeon” folktale, it follows a young girl whose recent release from a psychiatric institution sees her reunite with her sister but also brings about a volatile home life as she deals with her mother’s ghost and the cruel menace of her stepmother. Kim Jee-woon’s suffocating atmosphere allows the eerie suspense to fester, soaking into the viewer’s mind as the haunting tale of hostile tension gradually evolves into a poignant meditation on grief, guilt, and reality. Striking visual design choices and a rich, purposeful color palette only enforce this air of slow-burn unease, making A Tale of Two Sisters a masterpiece of simmering horror that achieves the rare feat of being even more frightful on rewatch. 19 'A Quiet Place' (2018) Image via Paramount Pictures Silence has always been a weapon in horror cinema, a tool that filmmakers can use to conjure suspense and anticipation with profound impact. When it’s used in a scene, it’s effective. When it’s used throughout an entire movie, it’s frightfully unbearable. A Quiet Place proves this point in glorious fashion, unfolding in a post-apocalyptic world where humanity has been decimated by blind alien creatures with acute hearing. The Abbott family survives by communicating through sign language, but the ever-present threat of a single mistake leading to an alien attack weighs heavily on each of them. Masterfully written and directed by John Krasinski, A Quiet Place delivers 90 minutes of ceaseless tension, but it is smart enough to fill the silent dread with plenty of character work. It ensures the movie isn’t merely an exercise in sound design, but an emotionally-charged story of familial connection that audiences care deeply about. 18 'A Girl Walks Home Alone at Night' (2014) Image via Vice Films What is a vampire? Looking beyond the literal meaning, it is a fascinating question to ask in reference to storytelling, one the 2014 Farsi-language film A Girl Walks Home Alone at Night answers in many different ways. Through the perspectives of a poor hard-working man and his drug-addicted father, a prostitute, and a thuggish criminal, the film depicts its nameless vampire (Sheila Vand) as a ruthless killer, a violent savior, a seductive romantic, a hope of escape, and as a force of nature. Even in defiance of the film’s ominous title, it presents vampires as a female fantasy of invulnerability and power, with the vampire roaming the nighttime streets of Bad City with a commanding fearlessness. Bolstered by its captivating black-and-white cinematography and its emphasis on style and atmosphere over narrative drive, A Girl Walks Home Alone at Night is a treat of indie horror as well as a striking directorial debut from Ana Lily Amirpour. 17 'The Descent' (2005) Image via Pathé Distribution A visceral gem of British horror, The Descent offers an impressionable mixture of frightful imagery, claustrophobic intensity, and potent emotional trauma. It focuses on a group of six friends whose spelunking adventure in the Appalachian Mountains turns into a frenzied nightmare when they learn they are lost in an unmapped cave system and find themselves being hunted by flesh-eating, humanoid creatures. While director Neil Marshall is renowned for his bloodthirsty visual horror—and every drop of that gory goodness is on full display here—The Descent thrives as the best example of his command of sickening, squeamish tension. The confined rocky passageways and near-total darkness present an assault on viewers’ sensory fears, while the ghastly design of the creatures evokes a response of raw, primitive terror every time they are glimpsed, making for one of the scariest movies of the 21st century. 16 'Sinister' (2013) Image via Lionsgate Films While it was criticized by some for its use of recycled horror tropes, Sinister has come to be lauded by genre fans as being one of the most frightfully scary movies ever made. It imposes itself from its opening scene—Super 8 footage of a family being hanged—before shifting focus to Ellison (Ethan Hawke), a struggling true crime writer who has moved his unsuspecting family into a murder house hoping he can gain some insight into the Stevenson family killings and revitalize his career. Things take a dark turn when he discovers a series of snuff films tied to a pagan Babylonian god. Scott Derrickson’s ability to weaponize ambient dread is the backbone to Sinister’s horror. The Super 8 footage is incredible at making viewers feel like helpless voyeurs and evoking a sense of stomach-churning unease, a visceral feeling that is brilliantly supported by the unsettling sound design and score. There is no doubt that Sinister uses age-old horror tricks, but it repurposes them wisely, making for a truly terrifying viewing experience that, on occasion, feels as though it has the essence of evil baked into its very existence.
