Grumble Grumble Grumble
Based on one of the early works of Osamu Tezuka (considered the Godfather of Japanese Manga) with a 'Retro Art Deco' anime style, and directed by Rintaro, released back in 2001. The animation was done by Madhouse studios, and was one of the first Anime productions to have a seamless integration of CGI effects with traditional hand drawn animation... A very good movie, (and I like the choice of background music during the movie climax...)

And this is a valid Anime topic... Moving...
