RELEASE DATE: January 17, 2012
Kei, the college boy, has become a stern warrior in the service of Gantz, a black sphere that brought him and Masaru inexplicably back to life after a fatal encounter with an oncoming subway train. He and others among the newly dead accumulate points by killing aliens on missions assigned to them by Gantz. With 100 points, they can either escape their limbo and lose all memory of their time there or return another person to life.
The original live action Gantz is currently available. Check out the trailer to Gantz 2: Perfect Answer here.
