Born in Scotland and after several roles on British television, McCallum got his big break in America with the 1960s spy series "The Man From U.N.C.L.E.", in which he played agent Illya Kuryakin. He co-starred with Robert Vaughn, who played the spy Napoleon Solo.


McCallum earned a pair of Emmy nominations for the series and worked steadily thereafter. He had, among others, roles in the films "The Great Escape" and "A Night to Remember". He also starred in a memorable episode of the creepy sci-fi anthology series "The Outer Limits," "The Sixth Finger," playing an ordinary man who volunteers to undergo an evolutionary breakthrough at accelerating speed.

McCallum returned to television with a starring role in the 1975 NBC series "The Invisible Man," but the show, despite its then-revolutionary special effects, lasted only one season. His unlikely last act on television was with CBS's "NCIS." McCallum played Chief Medical Examiner Donald "Ducky" Mallard, an eccentric and skilled professional who served as the patriarch of the show's investigators.

McCallum is survived by his wife of 56 years, Katherine McCallum, four children (Paul McCallum, Valentine McCallum and Peter McCallum), daughter Sophie McCallum and eight grandchildren.
