Where would they have gone with this?
If The Lieutenant hadn't been cancelled in the spring of '64, would the show wind up sending him to Vietnam and would it have been a Vietnam version of Combat!. Or would he somehow have remained at Camp Pendxleton, training troops, so they could keep the show a mix of military and other themes?
Also, considering all the war movies that came out during World War II and even Korea, it seems strange that there wasn't a Vietnam version of Combat while the war was on. I guess it was too controversial a war, (although Korea, was, too). If you watch TV series of the late 60's and early 70's, it's kind of hard to tell that a war is going on.
The past is a series of presents. The present is living history we are privileged to witness
