All 10 Best Ella Purnell Movies Ranked (Best to Worst)

Mark Romanek's adaptation of Kazuo Ishiguro's novel stands as an exquisitely calibrated study of quiet human devastation. Bathed in faded sepia tones and scored with haunting restraint by Rachel Portman, the story tracks clones bred purely for organ donation, exploring their futile attempts to grasp love and self-determination against a bleak mid-century British backdrop. The film succeeds because it treats monumental ethical horror as an accepted bureaucratic mundane fact. Playing the young Ruth alongside Carey Mulligan's younger counterpart, Purnell handles fragile, defensive mannerisms with startling intuition. She plants the exact psychological seeds of insecurity and possessiveness that Keira Knightley later harvests, marking an astonishing early milestone in her career.

Frank Hall Green's independent drama strips away conventional road movie tropes to deliver an unflinching portrait of trauma across the rugged expanse of Denali National Park. The film works through patient, tactile immersion, juxtaposing brutal emotional abuse with the overwhelming, indifferent beauty of the Alaskan wilderness. When an abandoned teenager forms a hesitant bond with an aging backpacker, the narrative avoids easy sentimentality in favor of genuine psychological healing. Purnell delivers an absolute tour-de-force performance here as Mackenzie. Carrying virtually every frame with raw defiance and trembling vulnerability, she commands the quiet spaces between survival and grief, establishing her credentials as a world-class dramatic protagonist.

Tim Burton crafts a signature blend of macabre fairy-tale design and kinetic adolescent fantasy inside this adaptation of Ransom Riggs's popular novel. Filled with stop-motion monstrosities, temporal loops, and exquisite mid-century seaside art direction, the narrative charges forward with gleeful, gothic pulp momentum. It remains Burton's most visually coherent fantasy adventure of the 2010s, balancing bizarre set pieces with genuinely affectionate oddball camaraderie. Floating above it all as the aerokinetic Emma Bloom, Purnell grounds the surrounding visual madness with earnest warmth and retro elegance. Her chemistry with Asa Butterfield anchors the fantastical stakes, lending emotional gravity and old-Hollywood charm to an otherwise dizzying spectacle.

Gustavo Ron's adaptation of Sally Nicholls's novel charts the daily life of an inquisitive eleven-year-old boy fighting terminal leukemia, relying on wit, scrapbooks, and unflinching childhood curiosity rather than manipulative clinical misery. The direction remains nimble and tender, sidestepping cheap tearjerker cliches by focusing intently on how youth navigates existential finality through imagination. The ensemble handles difficult subject matter with buoyant grace. As Kayleigh, the protagonist's cousin who provides an anchor of relatable teenage normality amid hospital visits, Purnell shows her innate gift for unforced, organic realism. She offers subtle dramatic support that balances the production's emotional peaks, proving her intuitive grasp of nuanced kitchen-sink drama early on.

Zack Snyder's blood-splattered, neon-soaked romp reconstructs Las Vegas as a walled-off quarantine zone populated by organized, mutating undead legions. Packing massive firearm choreography, explosive heist tropes, and grim sun-baked cinematography into an expansive ensemble adventure, the narrative thrives on uninhibited genre indulgence. Despite the relentless body count and CGI carnage, the central dynamic rests upon broken family reconciliations inside the apocalyptic playground. Purnell steps in as Kate Ward, the moral heartbeat of the mercenary crew who refuses to prioritize dirty cash over abandoned refugees. Facing down Dave Bautista's hulking patriarch, she projects fierce independence and grounded empathy, cutting cleanly through the chaotic blockbuster noise.

Unfolding entirely in real-time within the claustrophobic confines of a teenager's bedroom, this intense British thriller examines modern adolescent vulnerability in the social media era. Director Ben Chanan builds relentless, ticking-clock momentum as an anonymous hacker weaponizes digital footprints to systematically dismantle a high schooler's reputation. While the narrative squarely centers on Maisie Williams's panicked lead, the surrounding web of schoolmates illuminates the insidious cruelty of peer pressure and cyber harassment. Purnell appears as Megan, an estranged close friend whose past interactions trigger critical plot developments. Her brief, urgent presence injects sharp social consequence into the drama, magnifying the stakes of this chilling digital chamber piece.

Ryan Eslinger approaches the classic extraterrestrial mystery not through bombastic invasions, but via dense mathematical theory, audio frequencies, and college-level orbital mechanics. Anchored by Alex Sharp's hyper-fixated math prodigy and Gillian Anderson's watchful professor, the film constructs an intellectually patient puzzle around a bizarre sighting at the Cincinnati airport. It favors lecture halls, chalkboard formulas, and understated bureaucratic surveillance over flashiness. In this cerebral environment, Purnell plays Natalie, a grounded girlfriend who anchors the protagonist's spiraling academic obsession. While the script underutilizes her dramatic ceiling, her practical warmth lends crucial human balance to an otherwise hyper-analytical, algorithm-heavy procedural.

Chronicling the short, kinetic life of artist and photojournalist Dan Eldon, this biopic captures the chaotic optimism of young activists chronicling civil strife in late-twentieth-century East Africa. Director Bronwen Hughes injects vibrant collages, diary sketches, and percussive pacing to mirror Eldon's artistic sensory overload, although the film occasionally slips into well-worn romanticized tropes of Western aid work. Purnell features as Marine Harrison, a bright, spirited connection to the protagonist's London roots. She brings effortless charm and effortless period flair to her scenes, offering a brief glimpse into the personal life Eldon leaves behind, even as the narrative shifts focus toward frontline conflict.

Set against the tense 48-hour countdown to the D-Day landings, this historical drama sidelines broad military skirmishes to examine Winston Churchill's stubborn resistance to Operation Overlord. Brian Cox gives an explosive, gravelly turn as the Prime Minister, wrestling with his painful memories of Gallipoli while butting heads with Dwight Eisenhower and King George VI. The stagey staging often feels emotionally repetitive, yet several individual character exchanges maintain crackling energy. Purnell portrays Helen Garrett, Churchill's timid but observant newly appointed secretary. Despite the film's melodramatic excesses, her nervous dignity opposite Cox provides humanizing counterweight, turning brief secretarial dictations into surprisingly moving generational friction.

Juan Carlos Fresnadillo's psychological chiller bridges parallel storylines across England and Spain, tracking two terrified children stalked by a faceless entity dubbed Hollow Face. Boasting gloomy, atmospheric lighting and Clive Owen's committed parental anguish, the production struggles under the weight of an unconvincing psychological twist that deflates its early supernatural tension. The creature design and fragmented storytelling never fully synthesize into a coherent dread. Even with the muddled tonal direction, Purnell turns in an expressive performance as Mia, the troubled daughter whose discovered storybook unearths buried family nightmares. She conveys genuine primal fright, standing out as a bright spot in an otherwise disjointed exercise.
