I wasn’t sure, at first, if this Youtube film clip is genuinely from 1969, or just made to resemble one of that period, but this is pretty cool! The narrator sounds very familiar.
Plenty of discussion points in this one!
Update: That sure does look like Marj Dusay (who stole “Spock’s Brain” in “Star Trek”) as the ummm, housewife. The Youtube comments say her husband is played by Wink Martindale, later to become a game show host. The narrator is probably Vic Perrin or Edward Everett Horton. (Suggestions welcomed.) I also found the segments of the same footage, in black/white, incorporated into a similarly-dated French video (1969). Amazing!
