I'm not really quite sure what this new Japanese movie, Casshern, is all about. From the looks of the trailer, I would say that the movie looks quite cool. Here is a summary:
In a world with an alternate history, a great war finally comes to an end leaving the earth diseased and polluted. The geneticist Dr. Azuma vies for support from the government for his neo-cell treatment that he claims can rejuvenate the body and regenerate humankind. The government leaders, guarding their own deeply entrenched powers, turn down the professor. Driven to complete his work, Dr. Azuma accepts a secret offer from a sinister faction of the powerful military. After an incident occurs in Dr. Azuma's lab, a race of mutant humans known as the Shinzo Ningen are unleashed upon the world. Now only the warrior known as Casshern, reincarnated with an invincible body, stands between the Shinzo Ningen and a world on the brink of annihilation.

So, it's apparently based off of a 1973 anime of the same name ... but this time, the theme song is by (oh, god) Utada Hikaru ...
The film sounds like it'd be fun to see, if nothing else, so if anyone has news about it, please tell me!
