David McCallum (the actor) has a new WikiTree profile.
Do you remember Illya Kuryakin from The Man from U.N.C.L.E.? No? How about Lieutenant Commander Eric Ashley-Pitt in the 1963 flm 'The Great Escape'? (if you are English, that film was on every Christmas. Christmas just wasn't Christmas without 'The Great Escape'...)
How about Doctor Donald "Ducky" Mallard from NCIS?
McCallum also appeared in Colditz, Sapphire & Steel, Murder, She Wrote, seaQuest DSV, and Babylon 5.
And he's here on WikiTree!
