Demi Moore reveals granddaughter inspired her to back climate documentary 'Groundswell'

Demi Moore is opening up about the deeply personal motivation behind her newest project, a climate documentary, titled 'Groundswell'.Moore, 63, serves as executive producer and narrator of the upcoming documentary that promotes climate activism through a positive lens, focusing on regenerative agriculture and sustainable farming as pathways to healing the planet. Speaking with PEOPLE, she explained how her three daughters with ex-husband Bruce Willis - Rumer, 37, Scout, 34, and Tallulah, 32, and her three-year-old granddaughter Louetta Isley Thomas Willis, drove her commitment to the project."I look at that and I say, 'What am I doing today to leave our planet better for my grandchildren and my grandchildren's children?'" Moore told the outlet. "What we do today, on all levels, creates what our future will look like. I think our planet is clearly crying and hurting."Moore first learned of the filmmakers' work while on a river rafting trip in the Grand Canyon with the film's producer. She was moved by its solution-oriented and hopeful approach, describing it as the kind of storytelling she wanted to be part of.'Groundswell' is the third film in a trilogy by husband and wife filmmakers Josh and Rebecca Tickell, following '2020's 'Kiss the Ground' and 2023's 'Common Ground'. The pair travelled around the world to communities where regenerative agriculture has made a measurable positive impact on the climate, from Uganda to India to Brazil. The ultimate goal of the film is to advocate for the transition of one billion acres of farmland globally to regenerative management.Moore co-narrates the documentary alongside Woody Harrelson, her 'Indecent Proposal' co-star who has served as narrator across all three films in the trilogy and also serves as an executive producer of 'Groundswell'. "I know truly how committed and passionate Woody has been around this subject matter," Moore said. "We both share having three adult daughters, and I think you do feel a greater responsibility as a parent to do whatever part you can to protect this beautiful planet."The film also features Laura Dern, Jason Momoa, Donald Glover and Rosario Dawson among its participants.Moore played a significant role in developing the script and opens up at the end of the film about how becoming a grandmother deepened her commitment to environmental advocacy. Director Josh Tickell described her as a "spectacular" storyteller, recalling how she insisted on returning to the studio to re-record a line she was not satisfied with. "The commitment that she had, we said, 'Let's go back in,'" he recalled. "So we turned the lights on, everybody came back in, got the microphone set up, and we did it until it was right."'Groundswell' debuted at the Cannes Film Festival last month, where Moore also served as a juror. "I can't tell you the excitement that it all aligned. We could not have asked for a better platform for this film to be launched," she said of the timing.Moore's next personal step in her sustainability journey was a simple one, planting her own small garden at home. "The more we are seeking to create that change, just in coming from a more gentle, kind, loving, compassionate place within ourselves to one another, it also then extends outward to our surroundings, our environment," she said. "I really do see it as part of the answer for creating a healing within ourselves and within the ground."'Groundswell' is available to stream from June 5.
