In the shadows of one man’s mind lurks a horde of monsters, each more unpredictable than the last. Split redefines terror by turning the human psyche into a battlefield.
James McAvoy’s chilling portrayal of a man harbouring 23 distinct personalities in M. Night Shyamalan’s Split (2016) catapults psychological horror into uncharted territory, blending clinical realism with supernatural dread. This film not only revives Shyamalan’s reputation but also sparks vital conversations about mental illness, trauma, and the blurred line between victim and villain.
- McAvoy’s transformative performance as Kevin Crumb, embodying over two dozen personalities, stands as a masterclass in acting versatility and physicality.
- Shyamalan masterfully dissects dissociative identity disorder (DID), weaving real psychological insights with genre-defying twists that challenge perceptions of monstrosity.
- The film’s legacy endures through its influence on the superhero-horror hybrid, culminating in the Glass trilogy, while igniting debates on ethical portrayals of mental health in cinema.
Unleashing the Horde: Split’s Descent into a Fractured Psyche
The Sinister Abduction: A Nightmare Unfolds
Three teenage girls—Claire (Haley Lu Richardson), Marcia (Jessica Sula), and Casey Cooke (Anya Taylor-Joy)—are thrust into unimaginable horror when they are kidnapped from a car park by a seemingly mild-mannered man named Kevin Wendell Crumb. What begins as a routine birthday outing spirals into a claustrophobic ordeal as they awaken in an underground labyrinth of locked rooms and bizarre rituals. Kevin, however, is no ordinary captor; he is a vessel for 23 distinct personalities, each with its own voice, mannerisms, and agendas. The film opens with disorienting close-ups and shaky camerawork, immersing viewers in the girls’ panic while subtly introducing McAvoy’s chameleon-like transformations through fragmented glimpses.
Casey’s backstory emerges gradually, revealing a childhood marred by abuse at the hands of her father, which parallels Kevin’s own fractured history. Flashbacks, rendered in desaturated tones, underscore themes of inherited trauma, positioning Casey not merely as prey but as a survivor with her own dissociative tendencies. Shyamalan’s direction excels here, using tight framing to amplify confinement, where every creak of a door or shift in Kevin’s posture signals an impending personality switch. The narrative builds methodically, eschewing jump scares for a slow-burn tension that grips like a vice.
Production notes reveal that the film’s underground lair was constructed on practical sets in Philadelphia, allowing for authentic acoustics that heighten the sense of isolation. Cinematographer Mike Gioulakis employs shallow depth of field to blur backgrounds, forcing focus on faces—especially McAvoy’s—which contort with eerie precision. This sequence sets the stage for the psychological cat-and-mouse game, where survival hinges on understanding the captor’s internal chaos.
Portraits in Madness: The 23 Personalities Dissected
At the heart of Split lies its audacious depiction of dissociative identity disorder, formerly known as multiple personality disorder. Kevin’s alters range from the flamboyant fashion designer Barry to the childlike Hedwig, who speaks with a pronounced limp and innocence masking danger. Patricia, the matriarchal figure, imposes order, while Dennis and Barry engage in ritualistic cleansing to appease the emerging Beast—a superhuman entity promising apocalypse. Shyamalan consulted psychologists to ground these portrayals, drawing from real case studies while amplifying for horror effect.
Each personality manifests through meticulous physicality: Hedwig’s oversized glasses and Swedish accent, Dennis’s rigid posture and obsessive cleaning. McAvoy’s research involved shadowing DID patients and therapists, resulting in performances that feel unnervingly authentic. Critics have praised this as a breakthrough, yet the film courts controversy by linking DID to superpowers, a trope that mental health advocates decry as stigmatising. Nonetheless, it provokes thought on how trauma births these ‘protectors’ within the mind.
The Horde, as the personalities collectively call themselves, operates like a dysfunctional democracy, with ‘the light’—Kevin’s core self—suppressed by dominant alters. Scenes of internal boardroom meetings, visualised through surreal dissolves, humanise the horror, suggesting a psyche in perpetual civil war. This structure echoes real DID therapy techniques, where integration is key, but Shyamalan twists it into a powder keg primed for explosion.
One pivotal sequence sees Casey manipulating Hedwig via shared drawings, a nod to art therapy’s role in DID treatment. The innocence of crayons contrasts the grim reality, symbolising fractured innocence. Such details elevate Split beyond schlock, inviting viewers to empathise with the monster.
Tension in the Shadows: Shyamalan’s Directorial Sleight of Hand
M. Night Shyamalan, once hailed as a prodigy, reinvented himself with Split after a string of commercial disappointments. His signature style—long takes, domestic settings twisted into nightmares—shines through. The zoo sequences, intercut with Casey’s memories, use natural light filtering through enclosures to evoke primal cages, mirroring the characters’ mental prisons. Sound design, courtesy of West Dylan Thoms, layers whispers, echoes, and discordant strings to simulate auditory hallucinations synonymous with DID.
Shyamalan’s economy of storytelling avoids exposition dumps; instead, Dr. Karen Fletcher (Betty Buckley), Kevin’s therapist, pieces together the puzzle via phone sessions. Her sessions, filmed in sterile offices, provide clinical counterpoint to the visceral captivity, grounding the supernatural in pseudo-science. The director’s restraint in reveals—saving the Beast for the finale—builds unbearable suspense, reminiscent of his Signs era but refined.
Critics note influences from Hitchcock’s Psycho, particularly the maternal alter Patricia echoing Norman Bates. Yet Shyamalan infuses modern relevance, touching on societal neglect of mental health. The film’s 18-month shoot faced budget constraints, forcing innovative practical effects over CGI, which lends a gritty tangibility absent in many contemporaries.
Beast from the Id: Trauma’s Monstrous Evolution
The Beast’s emergence marks Split‘s genre pivot, transforming psychological thriller into body horror. Rendered through McAvoy’s contortions—no prosthetics, just yoga-honed flexibility—and subtle practical enhancements like elongated limbs via forced perspective, it embodies Freud’s id unleashed. Porphyria, the real disorder cited, causes photosensitivity and strength, mythologised here as evolutionary superiority.
Casey’s confrontation with the Beast atop Philadelphia skyscrapers fuses superhero spectacle with intimate dread. Her scars, bared vulnerably, symbolise shared victimhood, culminating in a mercy that blurs predator-prey lines. This arc critiques vigilante justice fantasies, questioning if trauma forges heroes or horrors.
The film’s coda, linking to Unbreakable via David Dunn’s sighting, retroactively elevates both, birthing the Eastrail 177 Trilogy. This meta-layer rewards rewatches, revealing foreshadowing like newspaper clippings fans dissected post-release.
Survivor’s Gaze: Casey’s Unbreakable Spirit
Anya Taylor-Joy’s Casey Cooke anchors the film, her wide-eyed intensity conveying quiet resilience. Orphaned and abused, Casey’s hunting skills—honed with her uncle—become tools of defiance. Her interactions with alters reveal empathy born of pain, subverting final girl tropes by humanising the antagonist.
Flashbacks, directed with handheld intimacy, expose patriarchal violence, linking personal trauma to broader societal ills. Casey’s choice to spare Kevin echoes therapeutic forgiveness, though ethically fraught. Taylor-Joy’s performance, honed from The Witch, cements her as horror’s new scream queen.
Effects Mastery: Practical Nightmares
Split‘s practical effects wizardry, led by SFX supervisor Chris Murphy, prioritises illusion over excess. Personality shifts rely on McAvoy’s makeup tweaks—scars appearing via contouring—and camera tricks for the Beast’s ascent up walls. No green screens mar the authenticity; rain-slicked exteriors were shot guerrilla-style for raw energy.
The Beast’s purge scenes, with ingested toxins granting abilities, use pyrotechnics and wirework seamlessly. Critics lauded this old-school approach amid CGI dominance, evoking The Thing‘s metamorphoses. Budgetary ingenuity amplified impact, proving less yields more in terror.
Sound effects amplify mutations—cracking bones, stretching sinews—synced to a score blending orchestral swells with industrial clangs, immersing audiences in corporeal horror.
Legacy of Controversy: Horror Meets Reality
Split grossed over $278 million on a $9 million budget, revitalising Shyamalan’s career and spawning discourse. Mental health groups criticised its supernatural DID link, yet defenders argue artistic license spotlights ignored disorders. Its influence permeates Glass (2019) and echoes in shows like Legion.
Culturally, it probes identity in fragmented digital age, where social media personas mimic alters. Box office success spurred Universal’s Blumhouse partnership, reshaping low-budget horror viability.
Ultimately, Split endures for forcing confrontation with inner demons, reminding that true horror resides not in shadows, but synapses.
Director in the Spotlight
Manoj Nelliyattu “M. Night” Shyamalan was born on 6 August 1970 in Mahé, Puducherry, India, to Malayali parents. His family relocated to Philadelphia when he was an infant, where he grew up immersed in American culture while cherishing Indian roots. A child prodigy, Shyamalan began filmmaking at age eight with a Super 8 camera, producing over 45 short films by high school. He studied biology at New York University’s Tisch School of the Arts but dropped out to pursue cinema full-time, supporting himself with odd jobs.
His feature debut Praying with Anger (1992) drew from autobiographical experiences, followed by Wide Awake (1998), a family drama starring Rosie O’Donnell. Breakthrough came with The Sixth Sense (1999), a ghost story grossing $672 million worldwide, earning six Oscar nominations and cementing his twist-ending trademark. Unbreakable (2000) explored superhero realism with Bruce Willis, while Signs (2002) blended alien invasion with faith, both box office hits.
The mid-2000s brought misfires: The Village (2004) divided audiences with its twist; Lady in the Water (2006), a fairy tale, underperformed; The Happening (2008) was panned for eco-horror.

Pivoting to television, he executive-produced Wayward Pines (2015-2016) and Servant (2019-present).
Split (2016) marked his Blumhouse resurgence, followed by Glass (2019) concluding the trilogy. Recent works include Old (2021), a beach-time horror; Knock at the Cabin (2023), an apocalyptic thriller; and Trap (2024), a serial killer concert chase. Shyamalan’s influences span Hitchcock, Spielberg, and Indian mythology; he often writes, directs, and produces via Blinding Edge Pictures. Married to Dr. Hai Xia Chu with three daughters, he resides in Philadelphia, blending family life with genre innovation. Awards include Saturns, Emmys for Tales from the Crypt, and a star on the Hollywood Walk of Fame.
