Michael Douglas, 82, wrote in his new memoir that he had an affair during the 1992 shoot of “Basic Instinct” with Jeanne Tripplehorn — not with Sharon Stone.
The actor’s memoir, “One Helluva Ride,” runs roughly 500 pages and was published Oct. 6, 2026. His answer upends the long-running rumor of an on-set romance between him and Stone, a decades-old Hollywood version of the story.
Paul Verhoeven directed the cat-and-mouse thriller, which pitted Douglas’ detective against Stone’s murder suspect. The film’s incendiary scenes made it a box-office sensation, and the heat between its two leads fueled years of speculation about a real-life romance. Douglas writes that all that attention landed on the wrong pair.
Douglas wrote: “The truth is, I fell very hard for Jeanne despite our nearly 20-year age difference.”
A Secret Kept in San Francisco
Tripplehorn, now 63, played a police psychologist and the love interest to Douglas’ detective. She was 28 and unmarried when the movie opened. Douglas was 47 and still married to his first wife, Diandra Luker.
The production filmed in San Francisco, and by Douglas’ account the two spent long stretches talking and getting to know each other away from the set. He went to considerable lengths to keep the relationship from the cast and crew, he writes.
Tripplehorn was at first unwilling to become involved with a married man, according to Douglas. She changed her position, he writes, after he told her that he and Luker had formally separated, that each was seeing other people and that the marriage was finished.
Douglas writes that he was prepared to leave his wife for Tripplehorn. What stopped him, he writes, was his recognition that another serious commitment right after nearly two decades of marriage would be the worst move available to him.
The affair lasted through production, and the two went their separate ways after the shoot. Douglas recalls Tripplehorn warmly, both as a performer and as a person. “With Jeanne, the passion you see onscreen reflects the genuine passion of our brief affair,” he added in the memoir.
Douglas told Page Six that he talked with Tripplehorn before putting the affair in the book and that she was fine with it. He has not seen her in years, he told Page Six. The point of such chapters, he said, is not merely the affairs but the significant friendships he formed through work.
Tripplehorn later starred in “Waterworld.” The actor Leland Orser, now 66, became her husband in 2000, and that same year Douglas wed Catherine Zeta-Jones, 57. The divorce petition came from Luker in 1995, though the split was not finalized until 2000. Dylan and Carys are the two children Douglas and Zeta-Jones share.
Zeta-Jones has joked about the book. She told NBC’s “Today” that she has “no intention of reading about him,” then told “The View” days later: “I’m going to read it.”
The Punch Douglas Denies
Douglas also takes on a second piece of “Basic Instinct” lore: the persistent story that he punched his director. He denies it in the memoir.
A heated argument set off the episode, after Douglas accused Verhoeven of giving Stone preferential treatment. Blood poured from the director’s nose as the two stood face to face, Douglas writes, describing a burst artery and a hemorrhaging Verhoeven. The production lost several full shooting days while the director recovered, and he returned on a reduced schedule under doctor’s orders.
Turner and a 40-Year Secret
The Tripplehorn disclosure is the second confession pulled from the book in a matter of days. An excerpt published before the memoir’s release revealed a relationship between Douglas and Kathleen Turner while the two made “Romancing the Stone” in 1984. Douglas kept it quiet for 40 years to shield Luker and the couple’s son, Cameron.
Turner responded to People: “Good heavens, what a fuss about something 40 years ago!”
Douglas writes of the “Romancing the Stone” period that he and Luker “were both having extramarital affairs, including my recent romance with Diane Thomas,” the film’s screenwriter.
Cocaine addiction, a cancer battle and a marriage to Zeta-Jones that included a brief separation all turn up elsewhere in the book, each of them recounted by Douglas.
Bonding Over Sons’ Addictions
Douglas describes bonding with Rob Reiner over their sons’ addictions. “We both had sons with serious drug issues and we both, at times, had been at the end of our rope,” he wrote. “It was a heartbreaking confessional for us, but I know we gave each other some measure of comfort during the hard times.”
The screen legend Kirk Douglas, his father, gets a chapter of his own in the memoir, which traces their complicated bond and the career choices that put it under strain. One of those choices required him to tell his father he would not play Randle P. McMurphy in “One Flew Over the Cuckoo’s Nest,” a role Kirk Douglas had been promised. Jack Nicholson took the part instead and won an Oscar for it.
Douglas said in an interview with the Associated Press that he probably would not have written the memoir while his father was alive, citing Kirk Douglas’ physical abuse. “I was very uncomfortable talking about the early years and his physical abuse,” he said.
He added: “He was of a generation that hit; my mother used the hairbrush. He was tough. That was also one of the reasons why it took a little time to warm up as we got older, and to forgive him.”
Douglas has worked more than five decades in the film industry. He has won two Academy Awards, best actor for “Wall Street” and a producing prize for “Cuckoo’s Nest.”
