Wikipedia Overview

The Return of the Man from U.N.C.L.E.: The Fifteen Years Later Affair is a 1983 American made-for-television action-adventure film based on the 1964–1968 television series The Man from U.N.C.L.E. starring Robert Vaughn and David McCallum reprising the roles they had originated on that program. Several of the crew from the series also worked on the film, which was produced by Viacom rather than Metro-Goldwyn-Mayer and/or Turner Entertainment. Leo G. Carroll had died in 1972, so Patrick Macnee was recruited to appear as an entirely different character, Sir John Raleigh, who had presumably taken over as Number 1 of Section I, the Director of U.N.C.L.E., after Alexander Waverly had died, and Carroll's photograph was displayed prominently in many scenes that featured Macnee's Sir John.
