Demi Moore on "The Substance" and resisting a toxic beauty culture

Demi Moore has lived in her home since 2005. "It's had some interesting incarnations," she said. "It was a house with three kids, and now it's just me and my silly pack of dogs."

It's hard to think of Moore as a grandmother who lives alone, but here she is, and doing what some are calling the best work of her career. Her latest film, "The Substance," is about an aging TV star who finds a sinister-looking potion that can give her a younger, more perfect version of herself, but at a terrible price.

"I put so much pressure on myself," she said, when discussing the value she had placed on her attractiveness in the past. "And I did have experiences of being told to lose weight. And all of those, while they may have been embarrassing and humiliating, it's what I did to myself because of that."
