Set in a retro-futuristic alternate world where the entire planet is divided between two opposing alliances, "Casshern" is at once visually entertaining and dramatically profound. The earth is left diseased and polluted through a "great war." The geneticist Dr. Azuma vies for support from the government for his "neo-cell" treatment which can rejuvenate the body and regenerate humankind. His appeals for funding is turned down by the government leaders who fear that the new technology will threaten their entrenched powers. Driven to complete his work by a desire to save the life of his beloved wife, Dr. Azuma accepts an offer from a sinister militaristic faction. However, Azuma's "neo-cell" cloning experiment goes haywire after an accident, and a race of mutant humans (quasi-androids) is unleashed upon the world. Tetsuya, Azuma's son, volunteers to be reborn as the bionic warrior Casshern in an attempt to save the world, and to clear the name of his father. Casshern valiantly sacrifices his own humanity in order to attain the powers needed to defeat mankind's powerful enemies. Haunted by the memories of his slain mother and having to deal with the super robot that has absorbed his father's consciousness, Casshern must put aside his own emotions in a desperate bid to save the human race. Veteran photographer and music video director Kazuaki Kiriya makes his feature directorial debut with this film loaded with high-voltage eye candy. Includes two bonus disc containing the director and production crew interviews, and a making of featurette(s).
