"Final Fantasy: The Spirits Within" is a science fiction film by Hironobu Sakaguchi, the creator of the Final Fantasy series of RPGs. It was the first animated feature to seriously attempt photorealistic CGI humans. The story follows scientists Aki Ross and Doctor Sid in their efforts to free Earth from a mysterious but deadly alien race known as the Phantoms, which has driven surviving humanity into "barrier cities." They are aided by Captain Gray Edwards and must compete against General Hein, who wishes to attack the aliens with the Zeus space cannon to end the conflict.
The film received mixed reviews and was a box office bomb, with losses of about $130 million (ouch!!)
It did pave the way for photorealistic CGI humans - "Final Flight of the Osiris" increased the level of realism shown.
