Mike Stone, the eldest brother of Oscar-nominated actress Sharon Stone, has died at 74 after battling a prolonged illness, the “Casino” star announced May 13, 2026.
The 68-year-old actress broke the news through an Instagram post that featured a photo of her late brother. “Mike Stone, my oldest brother,” Sharon wrote in the tribute. “Has passed away. Following an extended illness. We wish him peace.”
Sharon’s three sons — Roan Joseph Bronstein Stone, 25, Laird Vonne Stone, 21, and Quinn Kelly Stone, 19 — joined their mother in signing the emotional message, highlighting how deeply the loss has affected the entire family.
A Family Marked by Repeated Tragedy
This latest death adds to a devastating series of losses that have struck the Stone family in recent years. Sharon’s younger brother Patrick Stone died of a heart attack at 57 in 2023, a tragedy that followed the 2021 death of his 11-month-old son River, who died from organ failure.
The family’s grief continued when Sharon’s mother, Dorothy Marie Stone, died at 91 on March 26, 2025. After Patrick’s death, Sharon acknowledged the crushing weight of so much loss, telling supporters, “Yes, we’ve had a tremendous amount of loss in these last couple of years, as so many of you also have.” She encouraged followers to “continue to be kind,” a message she has emphasized repeatedly.
Sharon’s younger sister Kelly and numerous nieces and nephews, including Sharon’s three sons, survive Mike Stone.
An Actor Who Shunned the Spotlight
While Mike Stone pursued an acting career like his famous sister, he maintained a low profile throughout his time in the industry. His film work in the 1990s included a role in the 1996 Arnold Schwarzenegger action vehicle “Eraser,” along with appearances in the horror film “Malevolence” and three episodes of the daytime soap “The Bold and the Beautiful.” He continued working in recent years, appearing in the 2022 film “Destinos Opostos.”
The 1995 Sam Raimi western “The Quick and the Dead” gave Mike his most memorable role, allowing him to appear alongside Sharon and Gene Hackman in the stylized shoot-’em-up that later became a cult favorite among fans of the genre. The film remains a treasured piece of the Stone family’s shared legacy.
Despite his Hollywood connections, Mike lived most of his life away from the cameras, serving as a steady private presence in his sister’s life, a quiet counterpoint to her global fame.
Hollywood Friends Rally Around Sharon
Fellow actors rushed to offer condolences as news of Mike’s death spread. “The Princess Bride” actor Cary Elwes wrote, “Sorry for your loss, Sharon,” while “Younger” star Debi Mazar offered, “My condolences Sharon.”
The flood of sympathetic messages in the comments section reflected the deep respect Sharon commands in Hollywood circles and recognition that her family has endured extraordinary heartache.
Sharon’s Resilience in the Face of Loss
The actress has been candid about her own health struggles, including a near-fatal brain hemorrhage in 2001 that profoundly reshaped her perspective on mortality and family. She has channeled much of her energy into painting, philanthropy and advocacy work in recent years while continuing to take on selective acting roles.
Sharon’s openness about loss has become a defining theme in her public life, with friends and fans praising her willingness to discuss hardship — a quality that has helped countless followers facing their own grief feel less alone.
Her brief Instagram message wishing her brother peace now stands as the family’s official farewell, as first reported on the evening of May 13.
