Coralie Fargeat’s The Substance is like a facelift gone horribly, hilariously wrong. What starts as a dream of eternal youth quickly spirals into a nightmare of identity theft—only this time, it’s your own skin that’s doing the stealing. Demi Moore is perfect as Elizabeth Sparkle, a washed-up fitness queen desperate enough to inject herself with the titular “substance” that promises beauty in the form of a second self, played by the striking Margaret Qualley. This isn’t just a cautionary tale about vanity—it’s a blood-soaked ballet of body horror that’ll have you squirming and laughing in equal measure.
Moore and Qualley deliver electrifying performances, perfectly embodying the duality of Elizabeth Sparkle and her youthful alter, Sue. Moore’s portrayal of Elizabeth is a powerful mix of vulnerability and steely desperation. As a former TV star clinging to the remnants of her fame, she skillfully captures the emotional torment of a woman past her prime in an industry obsessed with youth. Whether she’s wiping away makeup in front of a mirror in frustration or grappling with the grotesque consequences of her choices, Moore brings depth to Elizabeth’s tragic unravelling.
Margaret Qualley, on the other hand, radiates seductive confidence as Sue. She plays the embodiment of every desire Elizabeth craves—young, beautiful, and magnetic—but beneath the surface, there’s a chilling undercurrent. Qualley transforms Sue from a fantastical beauty queen into a dangerously impulsive and unhinged character, making her descent into chaos as compelling as it is terrifying.
Together, Moore and Qualley mirror the internal and external conflicts of a woman at war with herself. Their performances elevate The Substance, turning it into a gripping commentary on self-worth, vanity, and the brutal cost of chasing eternal youth.
Dennis Quaid is surprisingly excellent, tapping into his infamous public image to play Harvey, a sleazy, larger-than-life TV exec who embodies everything toxic about Hollywood’s obsession with youth and beauty. Quaid’s performance is delightfully grotesque—his character is loud, flashy, and unapologetically predatory, pushing Elizabeth out of the spotlight and drooling over the younger, more marketable Sue. His over-the-top antics, paired with his moustache-twirling charm, are simultaneously revolting and fascinating, making Harvey the perfect personification of the industry’s ruthless exploitation of women.
One of The Substance‘s most striking features is how its vibrant, almost candy-coloured visuals starkly contrast with the gruesome body horror unfolding beneath the surface. Director Fargeat bathes scenes in bold, neon hues—bright pinks, electric blues, and blinding whites—that evoke the glitzy allure of Hollywood’s glamorous façade. These vivid backdrops serve as a stunning visual counterpoint to the visceral, grotesque transformations happening to Elizabeth and Sue. The bubbly, surreal aesthetic intensifies the horror as perfect bodies are ripped apart and stitched together, making the viewer squirm in discomfort while being seduced by the beauty.
This sharp juxtaposition highlights the film’s critique of the entertainment industry, where surface-level perfection masks a darker, exploitative reality. The contrast between the colourful, almost satirical sets and the terrifying bodily distortions elevates the horror, creating a dissonance that keeps audiences entrancingly horrified.
The Substance is a dazzling, grotesque thrill ride that stands out as one of the best horrors of the year. With sharp social commentary, outstanding performances from Demi Moore and Margaret Qualley, and a masterful blend of vibrant visuals and gore, Coralie Fargeat has created a film that is both beautiful and terrifying. Its biting satire on Hollywood’s obsession with youth and beauty makes it a must-see. ★★★★
