There are actually two promos in the following video. The first has Batman executive producer/narrator William Dozier extolling the value of his latest acquisition, The Green Hornet. Well, we all know how that ended, don't we? Anyway, the 2nd clip is from the ABC 1966 Fall Preview Special, narrated by Dick Tufeld (Lost in Space, Hollywood Palace), which, as Dozier would say on Batman, "we have already seen":
Yes, Dozier is on the set of Batman, particularly in the office of Commissioner Gordon. Come to think of it, he does look like Neil Hamilton's younger brother, doesn't he?
