 During the final season, David McCallum (I) (qv) guest starred as  a Russian villain named Ivan who was once partnered with General  Stockwell (Robert Vaughn (I) (qv)). This reunited the two former  _"Man from U.N.C.L.E., The" (1964)_ (qv) stars. The episode, "The  Say Uncle Affair", was formatted in the same manner as an episode of  _"Man from U.N.C.L.E., The" (1964)_ (qv), complete with "chapter  titles", the word "affair" in the title, and similar scene  transitions. It is thus far the last time that the two actors have  worked together.
