Final Fantasy: The Spirits Within is a 2001 science fiction film directed by Hironobu Sakaguchi, creator of the Final Fantasy franchise. It was the first photorealistic computer-animated feature film and the most expensive video game-inspired film until the release of Prince of Persia: The Sands of Time in 2010. It features the voices of Ming-Na Wen, Alec Baldwin, Donald Sutherland, James Woods, Ving Rhames, Peri Gilpin and Steve Buscemi.
The film follows scientists Aki Ross and Doctor Sid in their efforts to free a post-apocalyptic Earth from a mysterious and deadly alien race, the Phantoms, which have driven the remnants of humanity into "barrier cities". Aki and Sid must fight against General Hein, who wants to use more violent means to end the conflict.
Square Pictures rendered the film using some of the most advanced processing capabilities available at the time. A render farm of 960 workstations was tasked with rendering each of the film's 141,964 frames. It took a staff of 200 about four years to complete The Spirits Within. Square intended to make the character of Aki Ross into the world's first photorealistic computer-animated actress, with plans for appearances in multiple films in different roles.
