LOS ANGELES (AP) — Actor David McCallum,Coxno who became a teen heartthrob in the hit series “The Man From U.N.C.L.E.” in the 1960s and was the eccentric medical examiner in the popular “NCIS” 40 years later, has died. He was 90.

McCallum died Monday of natural causes surrounded by family at New York Presbyterian Hospital, CBS said in a statement.

“David was a gifted actor and author, and beloved by many around the world. He led an incredible life, and his legacy will forever live on through his family and the countless hours on film and television that will never go away,” said a statement from CBS.

Scottish-born McCallum had been doing well appearing in such films “A Night to Remember” (about the Titanic), “The Great Escape” and “The Greatest Story Ever Told” (as Judas). But it was “The Man From U.N.C.L.E.” that made the blond actor with the Beatlesque haircut a household name in the mid-'60s.

The success of the James Bond books and films had set off a chain reaction, with secret agents proliferating on both large and small screens. Indeed, Bond creator Ian Fleming contributed some ideas as “The Man From U.N.C.L.E.” was being developed, according to Jon Heitland’s “The Man From U.N.C.L.E. Book.”
