McCallum’s work with The Man From U.N.C.L.E. brought him two Emmy nominations, and he got a third as an educator struggling with alcoholism in a 1969 Hallmark Hall of Fame drama called Teacher, Teacher. He was 90.
McCallum is one of four original cast members whose contracts are up at the end of this season, along with Michael Weatherly, Pauley Perrette and Sean Murray.
