Legend of the Galactic Heroes: Overture to a New War

Legend of the Galactic Heroes: My Conquest Is the Sea of Stars
What they share
Both films are directed by Noboru Ishiguro, and they both carry the cerebral, epic, foreign gem mood tags, and they sit in Animation / Science Fiction / War territory. If that's the register that drew you to Legend of the Galactic Heroes: Overture to a New War, the second film will land in a comparable space — through a different lens.
What Legend of the Galactic Heroes: My Conquest Is the Sea of Stars is
You command a fleet in the Alliance’s last throw at the Empire’s wall and already know the charge is doomed. Then a young noble from the Empire and a disillusioned tactician from the Alliance begin outmaneuvering everyone above them.
