Douglas died of cancer at a motion picture industry retirement home in Los Angeles, according to an obituary from Michael Douglas’s production company, Further Films.
Douglas appeared in a number of films and TV shows, from the Steve Martin film Planes, Trains and Automobiles to TV shows Dallas, ER, The West Wing and Days Of Our Lives.
She is survived by her third husband, Donald Webster. The couple had been married for 15 years.
Born Diana Love Dill in Bermuda, the actress moved to New York to study at the American Academy of Dramatic Arts, where she met Kirk Douglas.
In May 1943, she appeared on the cover of Life magazine as a model, which her future husband saw.
“Kirk Douglas, by then serving in the Navy during World War II, saw her on the cover and told his shipmates he would marry her,” the obituary read.
The couple were married in November that year and had two sons, Michael and Joel, before divorcing in 1951.
Douglas married her second husband, actor Bill Darrid, in 1956. The couple were together until his death in 1992.
Douglas remained on good terms with her first husband and starred alongside him in a number of films. Her last film, It Runs In The Family, released in 2003, starred Kirk and her son Michael, and her grandson Cameron.
