Hyakumannen Chikyuu no Tabi Bander Book

Space Firebird 2772
Was sie teilen
Both films are directed by Osamu Tezuka, and they both carry the surreal mood tag, and they sit in Animation / Science Fiction territory. If that's the register that drew you to Hyakumannen Chikyuu no Tabi Bander Book, the second film will land in a comparable space — through a different lens.
What Space Firebird 2772 is
A gleaming lab. The hiss of sterile birth. Born in glass, raised by machines. The boy climbs through perfect skies, guided by Olga’s cold hands, until the horizon cracks. He traces the seams of a world that shouldn’t fit. A mid-period Tezuka meditation, pushing animation toward existential limits.
