McCallum is known for playing a pathologist in CBS’s hit TV series NCIS, which spawned several spinoffs.

On Monday, the Scottish-born actor passed away in New York. Natural causes caused his death.

He was described as a gifted actor and author who was loved around the world by CBS.

His legacy will forever live on through his family and the countless hours he spent on film and television.”

The Man from U.N.C.L.E. – in which he played a Russian agent – won him many fans, especially young women.

In 1968, the series ended, but he received several Emmy and Golden Globe nominations for his role as Illya Kuryakin.

He has appeared in films such as The Great Escape, The Greatest Story Ever Told, and A Night to Remember.

As a guest star, he appeared on Perry Mason and The Outer Limits. The son of classical musicians, he initially pursued a career in music before becoming an actor.

In addition to his role on NCIS, he also appeared on JAG, which led to the NCIS spinoff. After NCIS, other NCIS shows were produced, including NCIS: Los Angeles and NCIS: New Orleans.

Also, McCallum worked as a voice actor for children’s cartoons and video games.

His family described him as a “true Renaissance man”.

“He was the kindest, coolest, most patient, loving father. He always put his family first,” Peter McCallum said.

He was fascinated by science and culture and turned his passions into knowledge.

Based on his decades-long studies for his role on NCIS, he could conduct a symphony orchestra and (if necessary) perform an autopsy.”
