“The Substance” is a 2024 body horror film written and directed by Coralie Fargeat. The movie stars Demi Moore as Elisabeth Sparkle, a former Hollywood star who, after being dismissed by her producer (Dennis Quaid) due to her age, turns to a black-market drug that creates a younger version of herself, Sue (portrayed by Margaret Qualley), leading to unforeseen consequences.

Elisabeth Sparkle, once a celebrated aerobics television star, faces ageism in the entertainment industry. In an attempt to reclaim her youth and career, she uses an illicit substance that allows her to transform into a younger version of herself named Sue. The process requires them to alternate existences every seven days, resulting in a complex and ultimately perilous dynamic.

The film delves into themes of societal pressures regarding aging, especially for women in Hollywood, and critiques the relentless pursuit of youth and beauty. Critics have noted its audacious and grotesque imagery, with Rotten Tomatoes stating: “Audaciously gross, wickedly clever, and possibly Demi Moore’s finest hour, The Substance is a gasp-inducing feat from writer-director Coralie Fargeat.”

“The Substance” premiered at the Cannes Film Festival on May 19, 2024, and was subsequently released in the United States and the United Kingdom on September 20, 2024. As of October 2024, the film is available for streaming on Mubi and various Video On Demand platforms.
