Anyway, the starship in that movie bears a resemblance to an Imperial Star Destroyer.... but the movie is from 1974, predating Star Wars by several years.....

I'm sure this is nothing but a mere coincidence, but it's quite interesting.
There's also the fact that Yuuzhan Vong crab armour looks strikingly like the armour worn by the Dark Eldar of Warhammer 40K, but I'm not sure whether how many people would pay attention to that...
