Denis Arndt, the veteran actor best known for his memorable role questioning Sharon Stone in the iconic Basic Instinct scene, has died at the age of 86.

His family confirmed the news in an online obituary, stating that Arndt passed away earlier this week at his home in Ashland, Oregon, according to TMZ.

Arndt’s acting career began in 1974 with a role in The Magical World of Disney, following his service in the Vietnam War. He went on to perform in more than a dozen seasons at the Oregon Shakespeare Festival, earning respect as a skilled stage actor.

Despite his many roles, Arndt is most widely recognized for playing Lieutenant Phil Walker in Basic Instinct, a part that left a lasting impression in pop culture history.

On television, Arndt had recurring roles in series such as L.A. Law and Picket Fences, and made guest appearances on shows like Grey’s Anatomy, The Practice, and Supernatural per PEOPLE.

Per his obituary, he died peacefully in his bed at his beloved cabin home of nearly 50 years in Ashland, Oregon.

Born in 1939—the same year The Wizard of Oz brought color to the big screen—Arndt lived a life full of color, adventure, and passion. A decorated Vietnam War veteran, he served as a helicopter pilot and was awarded the Purple Heart twice. After flying in Alaska, he transitioned into acting, landing a lead role in his very first audition in Seattle. From there, his second career took off.

Arndt became a respected stage actor with multiple seasons at the Oregon Shakespeare Festival and eventually found success in Hollywood. He gained widespread recognition for his role in Basic Instinct and received a Tony Award nomination for his performance in Heisenberg on Broadway.

He is survived by his wife of 45 years, Magee Downey; their three children, Bryce, McKenna, and Tanner; four children—Scott, Tammy, Laurie, and Kirsten—from a previous marriage; many grandchildren, great-grandchildren, and great-great-grandchildren; and his niece, Beth.

Known for his charm, wit, rebellious spirit, and love for sailing, Denis Arndt lived with spontaneity and passion. A private memorial service will be held for the immediate family. In his memory, the family encourages everyone to “grab life by the balls and follow your passion.”
