After appearing in The Man From U.N.C.L.E., David McCallum appeared in numerous films and shows. The original "N.C.I.S." crew has always had McCallum, even though it has spun off into several different iterations, from Hawaii to New Orleans. McCallum is now known to a whole new generation as "N.C.I.S." "N.C.I.S." introduced McCallum to a whole new generation in 2003 by portraying Dr. Donald Mallard, the chief medical examiner.
As it turns out, McCallum played Ducky in two episodes of "J.A.G." and "N.C.I.S." before the show became its franchise. The RadioTimes reported that McCallum's character Ducky has appeared in only two episodes of this season, so he may be ready to say goodbye to the show soon. There is no indication whether these episodes will appear this season or the next. However, Ducky's appearance in Season 20 has yet to meet our expectations.
The show feels different from other shows
