So everybody knows the original Battlestar Galactica was a ripoff of Star Wars, right?
Well, in its “look” (and title), sure. In its plot, not especially. But in at least one instance the borrowing seems to have gone the other way:
Baltar: What of our bargain? My colony was to be spared!
Imperious Leader: I now alter the bargain.
(Battlestar Galactica pilot, 1978)Lando Calrissian: That wasn’t the deal!
Darth Vader: I am altering the deal. Pray I don’t alter it further.
(The Empire Strikes Back, 1980)
I think Leigh Brackett imporved on the original line though. Thank God George Lucas didn’t write Empire.
