Hollywood veteran David McCallum has reportedly died at the age of 90. He was known for his role as Dr. Donald "Ducky" Mallard on the hit drama series "NCIS." 

But McCallum first hit fame as Illya Kuryakin in the 1960s hit spy drama "The Man From U.N.C.L.E."

According to reports, McCallum passed away due to natural causes in New York City. He is survived by his five children, Peter, Val, Jason, Sophie, and Paul McCallum.

After the death of the actor, his son Peter McCallum has shared a statement where he paid tribute to his late dad.

He said, "He was the kindest, coolest, most patient, and loving father. He always put family before self. He looked forward to any chance to connect with his grandchildren and had a unique bond with each of them. He and his youngest grandson, Whit, 9, could often be found in the corner of a room at family parties having deep philosophical conversations."

Peter continued, "He was a true Renaissance man — he was fascinated by science and culture and would turn those passions into knowledge. For example, he was capable of conducting a symphony orchestra and (if needed) could actually perform an autopsy, based on his decades-long studies for his role on NCIS."

He spoke about his father's relationship with his mother: "After returning from the hospital to their apartment, I asked my mother if she was OK before she went to sleep. Her answer was simply, 'Yes. But I do wish we had had a chance to grow old together.'"

Peter continued, "She is 79, and dad just turned 90. The honesty in that emotion shows how vibrant their beautiful relationship and daily lives were, and that somehow, even at 90, Daddy never grew old."

The executive producers of "NCIS," Steven D. Binder and David North, also shared a statement following the death of McCallum, where they reminisced on their memories of working with the actor on the show.

Binder and North said, "For over twenty years, David McCallum endeared himself to audiences around the world playing the wise, quirky, and sometimes enigmatic, Dr. Donald' Ducky' Mallard."

Their statement continued, "But as much as his fans may have loved him, those who worked side by side with David loved him that much more. He was a scholar and a gentleman, always gracious, a consummate professional, and never one to pass up a joke."

"From day one, it was an honor to work with him and he never let us down. He was, quite simply, a legend. He was also family and will be deeply missed," the duo concluded.
