Michael Douglas honored his father Kirk Douglas on the first anniversary of his passing. The Kominsky Method star, 76, took to his Instagram on Friday, Feb. 5, to pen a moving tribute for the late Hollywood star. “Can’t believe it’s been a year since you left us,” Michael captioned a photo of himself with his dad. “At 103, you picked a good time to check out. I love you with all my heart! #KirkDouglas.”

Catherine Zeta-Jones commented on her husband’s post writing: “Love you Pappy🙏🏻😘.” Michael’s oldest son Cameron, who recently welcomed his second child, also paid tribute to Kirk on the one-year anniversary of his death. “A year you’ve been gone...Your influence and your Love continue to permeate my Life. I do deeply miss your presence though Pappy,” Cameron penned alongside a solo portrait of his paternal grandfather.

Kirk, who was born in 1916, died last February. Following his father’s death, Michael released a statement that read: “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.”

“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,” the Oscar winner continued. “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. 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. #KirkDouglas.”
