We hope he sent a birthday card too, but Michael Douglas shared some sweet wishes for his dad, legendary actor Kirk Douglas, on Facebook, too.

The elder Douglas turned 99 on Wednesday, and his son marked the occasion by sharing a photo showing him kissing his father’s head.

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

Michael Douglas, 71, was seen most recently in Ant-Man as Hank Pym and has said he’s up to return for the sequel, Ant-Man and the Wasp. In 2003, he starred with his famous, Spartacus-starring father (as well as his own son, Cameron Douglas, and mother, the late Diana Douglas) in the film It Runs in the Family.
