Douglas’ wife of 65 years, Anne Buydens, who arrived in a wheelchair, led the mourners at the Pierce Brothers Westwood Village Memorial Park and Mortuary in Los Angeles, according to People.com, which ran photographs before the service.

The “Sparticus” stars’ three surviving sons, actor Michael Douglas, Peter and Joel, were in attendance along with Michael Douglas’ wife Catherine Zeta-Jones.

Director Steven Spielberg, who thanked Douglas for his “fatherly advice” following the actor’s death, was in attendance wearing dark sunglasses and a dark suit, according to TMZ.

It was Michael Douglas who broke the news of his father’s passing with a post on Instagram, just days after his 103 birthday. “It is with tremendous sadness that my brothers and I announce that Kirk Douglas left us today at the age of 103. To the world, he was a legend, an actor from the golden age of movies who lived well into his golden years, a humanitarian whose commitment to justice and the causes he believed in set a standard for all of us to aspire to.”

Michael continued, “But to me and my brothers Joel and Peter he was simply Dad, to Catherine, a wonderful father-in-law, to his grandchildren and great grandchild their loving grandfather, and to his wife Anne, a wonderful husband.”

“Kirk’s life was well lived, and he leaves a legacy in film that will endure for generations to come, and a history as a renowned philanthropist who worked to aid the public and bring peace to the planet,” Michael added. “Let me end with the words I told him on his last birthday and which will always remain true. Dad- I love you so much and I am so proud to be your son.”
