Storied film actor Kirk Douglas celebrated his 99th birthday on Wednesday, and he marked the occasion with sweet well-wishes from his son.

Michael Douglas shared a red carpet photo with the legendary Spartacus star on Facebook in honor of his father’s big day.

In the image, Michael, 71, gives his father a sweet forehead kiss.

“Happy 99th Birthday Dad,” Michael wrote. “I love you.”

Michael has previously praised his father’s illustrious career, while thanking him for letting him forge his own path in the industry.

Michael’s wife, Catherine Zeta-Jones, echoed her husband’s sentiments in a sweet birthday post Wednesday.

“Happy Birthday to my dearest Father in Law, Kirk. 99 years young today. I love you with all my heart.”

Although Kirk has clearly lived a long life, the Honorary Academy Award winner recently told PEOPLE about how he nearly was a passenger on Elizabeth Taylor‘s husband’s private plane, which crashed and killed everyone aboard in 1958.

The actor’s longtime wife, Anne Buydens, wouldn’t let Kirk join on the plane ride – and thankfully so, as the Lucky Liz suffered engine failure.

“Why was I spared? I was so grateful,” Kirk told PEOPLE. “My wife has saved my life many times.”
