TIL - For his role as medical examiner "Ducky" on NCIS, he actually learned how to perform an autopsy.
Ah no way! I have fond childhood memories of watching re-runs of "The Invisible Man" and "The Man from U.N.C.L.E", and it was nice to see a seasoned and matured McCallum as "Ducky" in NCIS.
Childhood memories too of the Invisible Man and disappointment at Sapphire & Steel as it was a bit inscrutable to me. Never got into NCIS, but will take a look
You need to start with JAG, as both Gibbs & Ducky started there before they spun off NCIS as a separate show.
