Denis Arndt, who starred opposite Sharon Stone in Basic Instinct, has died aged 86. The Washington-born actor’s death is believed to have been unexpected, but no cause has been given.

An obituary shared online by his family confirmed that Arndt passed away earlier this week at his home in Oregon.

“It is with a heavy heart that I announce the passing of our dad, Denis Leroy Arndt,” it read.

“He died peacefully in his bed in his beloved cabin home of almost 50 years in Ashland, Oregon; he wouldn’t have had it any other way.”
