An emotional Michael Douglas was honored with a star in the Walk of Fame of Hollywood, like his proud father and giant Kirk colleagues who attended.
The actor, known for appearances in films such as Wall Street, Fatal Attraction and Basic Instinct, was recognized for his 50-year career at showbusiness on Tuesday.
Kirk, who will be 102 in December, is a star of the Golden Age of Hollywood, appearing in films like Spartacus. He sat in a wheelchair, just a few meters away from his son's star, as well as his own, which was revealed in 1960.
The veteran actor spoke to the fans, as Michael paid tribute to them.
Before he unveiled his star, Michael, 74, said, "My dad is here." In one month Kirk turns to 102. So, those of you who take the subject, making 80, missed a long time ago.
He returned to his father and said, "I know, no one is celebrating his 50th anniversary in business, it means so much to me that you are here today.
"Thank you for your advice, your inspiration and I will say it with all my heart, I am so proud to be your son."
Also attending the ceremony were Douglas's wife, Welsh actor Catherine Zeta-Jones and their son, Dylan.
Douglas described Zeta Jones, whom she married in 2000, "love of my life."
He added: "Thank you very much for your support, your love and patience. On the occasion of another week, we celebrate our anniversary, our 18th anniversary, thank you for the best 18 years of my life.
Douglas celebrates his 50th year in the showbusiness and is reflected in a successful career that saw him win the best actress for the portrayal of Gordon Gekko in 1987.
He said he was "fortunate enough to be part of both Hollywood and New Hollywood."
He said despite the many changes, "there are traditions that endure. Traditions such as this ceremony, the collective thread that allows us to pay tribute to those from each generation who create the stories that move us.
"For me, the 2,000 stars embedded in these pavements are more than the bronze title. They represent real people, women and men passionately passionate about what they did and to entertain people around the world."
Douglas's star was 2,648 at the Walk of Fame.
