I prefer the Starblazers (english dub)story to Yamato. It is editted a bit differently to focus more on the characters whereas Yamato is on the Space ship itself. Plus the voice work is more entertaining. Desslar, the leader of teh bad guys is generic-old-Japanese-man-voice, but in the English version he has this crazy high pitched English accent going on. Adds a lot more character to him. The live action movie isn't bad either and the ship now looks fantastic! Especially when they use the hadou-hou (wave motion gun). But it does compress the series quite a bit.
What I liked about Yamato though was that the guy looking after the engine of the ship was named Tokugawa. And Yamato was (is?) the 'central race' of Japan. Tokugawa was also the Shogun of Japan (i.e unofficial king of sorts) during the years of isolation and is generally considered the guy who brought the warring states of Japan together into one country. So Tokugawa drives the engines of Japan. </end history lesson>
I remember Battle Angel Alita! i thought that was a great anime!
Also in regards to Akira, at the time (iirc), it was the most expensive film ever made in Japan. Probably now exceeded
