Good for a reunion show that deserves special allowances for auld lang syne that otherwise would not fly for a regular show, a time to reminisce on the impossibility of twenty years flying by! and even worse another twenty since that yet again to 2006! Will someone quit turning the calendar instead of the second hand! Though McNee was truly good as Sir John, the sorrowful part was the loss fourteen years before, in '72, of inestimable and quite irreplaceable stellar veteran Leo G. Carroll/Mr. Waverly they were kind enough to acknowledge. What wasn't mentioned in other descriptions of the film was how Sir John's entrance into the fray was due to the death of Mr. Waverly whom he was replacing (I believe he was supposedly killed in a THRUSH attack, which while stretching the bonds of credibility that they only just now managed to kill him after so many years is still a well-deserved tribute to dear old Leo G.). As sharp as Carroll was, he deserved a larger role had the oversexed dolts of that age not been such abysmal failures at appreciating the treasure in their midst, though perhaps Vaughn & McCallum may have.
A fascinating connection most don't realize, including me, until today, thanks to the IMDb, is that in the '50s show Topper in which Carroll starred as Cosmo Topper, Robert Sterling played George Kerby, the debonair husband of the ghost couple that could be so frustrating for Cosmo, wife Anne Jeffreys playing Mrs. (Marion) Kerby, but Sterling also later played Captain Lee Craine in the Irwin Allen's movie, Voyage to the Bottom of the Sea, the part later taken by David Hedison in the TV version as Richard Baseheart took Walter Pigeon's place! Interesting connection: Man from UNCLE and Voyage to the Bottowm of the Sea by way of Topper! What Topper!
