Demi Moore revealed that her portrayal in Coralie Fargeat's visceral and haunting thriller, "The Substance," necessitated embracing a profound "level of vulnerability and rawness" regarding her on-screen physique. She unreservedly bared all for the film, a grotesque yet campy satire that skewers beauty standards, toxic masculinity, and female self-loathing. The movie's frequent and prominent nudity, coupled with its gruesome violence, garnered immense attention following its world premiere in Cannes.
In the film, Moore stars as Elisabeth Sparkle, a renowned actress who transitions into a celebrity host of a popular daytime exercise program. However, when she is usurped by a younger, more alluring star (Margaret Qualley), it ignites a fierce confrontation between the two women. One of the most graphic scenes in the movie showcases a naked and unforgiving bloodbath between Moore and Qualley, leaving the Cannes audience thoroughly enthralled and giving the film a thunderous reception on Sunday night.
