Essentially, they had seven of us describe our favourite characters and attributes of TNG. Here are a few screenshots from Promo #1:
Ian: "Data, the android... He wants to be human more than anything else."
Scene from "Encounter at Farpoint"; Wesley Crusher's voice over: "Wow!"
Scrolling text at base of screen: "Australian Star Trek fans discuss Star Trek: The Next Generation."
(Nine Network Australia, 1990.)
Pretty cool, eh? I must learn how to upload to Youtube some day...
