When the movie first came out, it showcased to the world what computer graphics is capable of, especially on the human animation and acting part.
This book provides a nice look into how Final Fantasy The Spirits Within was created.
The concept art included are mainly designs of vehicles, sets, props and storyboards. Since this is a "Making of" book, it talks extensively about how the art is related back to the story. Among them are subjects like creating flames, flares, using motion capture for acting, composition and other general production techniques.
Character design is lacking in the book. Even though several pages are devoted to each character, there wasn't any concept art on how they come up with the characters. All that is included are the bio stats, film stills, and 3D rendered posed models.
This is a great book companion to the movie.
