Throughout Powers’ career, the actress says she “has never neglected her theatrical roots,” appearing in plays both stateside and in the United Kingdom. The actress has appeared in productions of How the Other Half Loves, Under the Yum Yum Tree, Sabrina Faire, View from the Bridge, Oliver, Annie Get Your Gun, Matador, The King and I, Sunset Boulevard, and an off-Broadway production of The Vagina Monologues. She also acted on stage opposite her former Hart to Hart co-star, Wagner, in Love Letters, touring the U.S. with the show and “becoming the cast most associated with the play after over 500 performances.” Though Powers still works in Hollywood, the actress says she only spends part of her time there. She also has a farm on the South Downs in East Sussex, England, and a home in Kenya. In Kenya, she runs the William Holden Wildlife Foundation (WHWF), an organization that promotes conservation and environmental stewardship through educational programs. On her website, she refers to this as a “double life, one in front of the camera or on a stage and one in absolute dedication to the preservation of animals and the natural world.” In a WHWF podcast, Powers shared that “my first step into the complicated world of charitable enterprise was more of a leap of faith than a dainty step.” She formed the organization in 1982 in honor of her longtime partner, Oscar-winning Network actor William Holden, who died after suffering a fall the year prior. Powers shared with Closer Weekly that the couple had bonded over their love of wildlife. “We loved it,” Powers recalled. “Being outdoors, sleeping under the sky, tracking animals. It was sort of a real-life adventure,” she told the magazine. Powers had world-famous on-screen chemistry with Robert Wagner on Hart to Hart and, in a 2019 interview with Daily Mail U.K., she shared that the pair are still close to this day. The actress revealed that she often makes an effort to get together with her former costar when Wagner visits Los Angeles from his home in Aspen.ae0fcc31ae342fd3a1346ebb1f342fcb Though fans often speculated about their onscreen romance continuing offscreen, which Powers calls “absolutely hysterical,” the actress maintains that theirs was akin to a sibling relationship. “Siblings who really like each other—when we were working together, sometimes we would get into laughing fits and they’d have to send us home,” she quipped. “We can still push each other’s buttons today,” Powers told the outlet. “We laugh all the time,” she added. Powers says even she can’t describe the magic of the pair’s chemistry. “If I knew what the ingredients were, I would bottle it and make a fortune,” she said.
