They did a live-action Yamato movie about five years ago. Not that good; they compressed the entire mission into about two hours. The visuals were really good tho, very similar to the Battlestar Galactica reboot.
Then they rebooted the Yamato anime series with a 26-episode run. This is available a few places online, free, but with subtitles. It is truly excellent from both a visuals and a plot/character development standpoint. While it still follows the original year-long mission to Iscandar plot, with many of the same points and devices, it’s very much it’s own creature and much superior to the original Yamato and the edited/Americanized Starblazers.
