Coralie Fargeat's new film, 'The Substance,' stars Demi Moore as Elisabeth Sparkle, a fitness instructor who turns to an experimental treatment to regain her lost youth and beauty after being fired on her 50th birthday. This body horror film explores the destructive obsession with beauty and the resulting self-hatred that permeates Hollywood. The treatment allows Elisabeth to create a younger doppelganger, Sue, but comes with gruesome consequences and a disturbing cycle of identity. The film blends dark humor with horror, creating a visceral experience that critiques societal pressures regarding beauty. Fargeat's visual style is both grotesque and vibrant, drawing audiences into a surreal interpretation of aging and relevance in a youth-obsessed industry. Ultimately, 'The Substance' serves as a chilling reminder that the pursuit of beauty can lead to one's own downfall.
