I can only recall the it being called "Captain Nemo in outer space" at the time. I've seen production art dated '74 or '75 with a robot that eventually became Vincent.
At least Maximillian doesn't smoke four packs a day.
If you've seen the Tron Legacy trailer, there's a little hint about Disney's next remake project. ;)
Whatever Galactica's true origins, it's a no brainer every studio that turned Lucas down would try to come up with something of their own. Star Wars even played a part in Star Trek's transformation into a big screen movie.
And wasn't it Lucas himself who was quoted saying how he knew people would copy Star Wars, and he would sit down and enjoy the copies?
If the Space Battleship Yamato live action film comes out in the states, you just know some clueless idiot is going to call it an SW rip.
