Demi Moore has finally come clean -“I’m here to define who I really am at almost 62, and I don’t need to play by any rules that have existed up until now.” After decades of trying to control… See more

Demi Moore’s new movie, “The Substance,” which opens Sept. 20, is a dark comedy about the horrors of getting older as a woman in Hollywood. But it’s also a literal body-horror film — the basic premise is that Moore’s character, an aging actress-turned-celebrity-fitness-instructor named Elisabeth Sparkle, takes a strange elixir (the substance) that allows her to create a younger, more perfect version of herself.

And you see that creation in bloody, visceral detail. The movie kind of grossed me out, to be honest, but I couldn’t stop thinking about it afterward. And it was fascinating to see Moore, who has been open about her own struggles with her body image and has lived most of her life in the public eye, play this role.

I’ve been mesmerized by Moore for decades, starting in 1985 with “St. Elmo’s Fire,” when her husky voice and bold onscreen persona — in this instance, a kind of wildness that made her seem both alluring and destructive — first broke through. There was a period when it felt as if every movie Moore starred in was an event — “Ghost,” “A Few Good Men,” “G.I. Jane,” “Striptease,” “Indecent Proposal.” She eventually became the highest-paid actress in Hollywood, and also an early advocate for pay equity in the industry, long before the issue was part of the national discourse.

But even though Moore was such a visible celebrity of my teenage and early adult years, I never felt I knew much about her until reading her revealing 2019 memoir, “Inside Out,” which opens at the lowest point in her life, with the end of her marriage to Ashton Kutcher and her relapse into alcoholism. Moore’s struggles started early as the child of a mentally ill, alcoholic mother. But much of the book is about the extreme lengths she went to during her prime Hollywood days to control her body through disordered eating and exercise. Now in her 60s and a grandmother, Moore tells me she has finally grown comfortable in her own skin and, with “The Substance” and this stage of her career, is hoping to upend expectations about what it means to be an aging woman in an industry that both embraced and judged her harshly. (And a note: I asked Moore how her former husband Bruce Willis, who’s living with frontotemporal dementia, is doing, and she said he’s stable and OK, all things considered.)Megyn Kelly Said “F You, Taylor Swift” After The Singer Endorsed Kamala Harris And Tim Walz, And Here’s Why This Outburst Is A Problem:
