Just watched the first 3 "pilot" episodes of the 1978 Battlestar Galactica.
Wow. Talk about Superstellar Disco Party.
Where's a 'fro smiley when you need one?
I was really amazed at the little details in it that they kept from 1978 to today's BSG series. In particular, there were two civilian ships, the Astral Queen and the Rising Star, that look identical from 1978 to today. Some of the utilitarian cargo ships that look like they carry shipping containers strapped to a central axis are eerily identical. Obviously Galactica herself is very similar, too...
The font at the beginning though, and the way the words just zoom out of space straight at the screen... total Star Wars ripoff. The gun belts and coats of the viper pilots screamed "Han Solo," also. As well as the laser special effects, the ship model construction for fly-by shots, and the design and flight characteristics of the vipers. They were very similar to X-wing fighters.
What's funny, though... LucasArts came back in about 2000-2002 or so and did a dirty to the 1978 BSG: They obviously stole those cargo container ships as a design for their X-Wing Alliance game. I seriously wonder if that's part of why Universal chose to re-imagine BSG after their cease-and-desist from Fox studios 20-some years ago. I also wonder if some of the other BSG ships haven't been stolen elsewhere in sci-fi.
The mining ship from BSG-78 looks a lot like the mining ship that Ellen Ripley lands on that unfortunate rock in Alien.
Frankly, Galactica herself looks a lot like an Alliance Dreadnaught from Star Wars... which wasn't imagined until at least Return of the Jedi... I'm not completely certain that I even saw a dreadnaught in that movie. Which means that the dreadnaught-class LucasFilms ship was adapted from BSG, too. The earliest concrete example of a dreadnaught I know of is in the Timothy Zahn Star Wars books that came out in the mid-90's...
Even "wookieepedia" confirms the similarity.
