Shirow Masamune's manga, this film is entirely CG, but doesn't look it. They cel shaded motion-capture data, so it's kind of like Final Fantasy with anime drawn over all of the people. In other words, it is way better than Final Fantasy because the chartacters get the super-realistic movement of motion-capture without having to convince us they're human. This isn't your grandmother's anime!
And as a bonus, check out the teaser trailer for the Speilberg/Cruise modern-day adaptation of H. G. Wells' The War of the Worlds.
