Yamato 2520 was Yoshinobu Nishizaki's attempt at a sequel to Space Battleship Yamato, set several hundred years after the original series. However, Nishizaki was sued by Leiji Matsumoto for breach of copyright. Ultimately, Yamato 2520 was left unfinished after only three episodes (of planned ten) were released. The episodes came out on VHS and LaserDisc for home media. (Source: Wikipedia)
