Once a colossal movie star of the 1980s and ’90s, Demi Moore had largely retreated from the acting spotlight during the 2000s and 2010s. However, in 2024, she experienced a remarkable comeback with the film “The Substance.” This psychological body horror thriller not only captivated audiences but also served as a commentary on Hollywood’s tendency to quickly discard its older female stars in favor of younger talent. The film explores the desperate measures these seasoned actresses might resort to in order to stay relevant.

“The Substance” received the longest standing ovation at that year’s Cannes Film Festival and was subsequently nominated for several Oscars, including best picture, best director, best actress, and best original screenplay. It won the award for best makeup, solidifying its status as a landmark film. It was immediately recognized as Demi Moore’s finest film, also shining a spotlight on Margaret Qualley, known for her prowess in psychologically intense roles. Released just in time for the Halloween season, “The Substance” debuted on HBO Max and promptly climbed to the top of the streaming service’s most-watched movies list.

The transformation of Moore into a monstrous figure for “The Substance” is intriguing, but if you haven’t watched it yet and are unaware of what type of monster it involves, it’s best not to delve deeper. This film is most enjoyable when approached with minimal prior knowledge. If you’re familiar with the basic premise and can handle some of the most visceral body horror seen in recent times — akin to what’s usually found in low-budget B-movie camp — then you’re ready to experience “The Substance.”

Beyond their striking physical likeness that convincingly portrays them as the same character at different ages, Demi Moore and Margaret Qualley deliver outstanding performances, representing different facets of the same person grappling with conflicting decisions and their devastating consequences. The culmination is a body horror spectacle that divided audiences, yet writer-director Coralie Fargeat deserves commendation for her daring vision and execution.
