Final Fantasy: The Spirits Within is a 2001 adult animated 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. The film stars the voices of Ming-Na Wen, Alec Baldwin, Donald Sutherland, James Woods, Ving Rhames, Peri Gilpin, and Steve Buscemi, and follows scientists Aki Ross and Doctor Sid in their efforts to free a post-apocalyptic Earth from the Phantoms, a mysterious, deadly alien race who has 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.

Plot

In 2065, Earth is infested by alien life forms known as Phantoms. By physical contact Phantoms consume the Gaia spirit of living beings, killing them instantly, although minor contact may only result in an infection. The surviving humans live in "barrier cities" protected by energy shields that prevent Phantoms from entering, and are engaged in an ongoing struggle to free the planet. After being infected by a Phantom during one of her experiments, scientist Dr. Aki Ross (Ming-Na Wen) and her mentor, Dr. Sid (Donald Sutherland), discover a means of defeating the Phantoms by gathering eight spirits: unique energy patterns contained by various lifeforms. When joined, the resulting energy wave can negate the Phantoms. Aki searches for the sixth spirit in the ruins of New York City when she is cornered by Phantoms but rescued by Captain Gray Edwards (Alec Baldwin) and his squad Deep Eyes, consisting of Master Sergeant Ryan Whittaker (Ving Rhames), Neil Fleming (Steve Buscemi) and Corporal Jane Proudfoot (Peri Gilpin). It is revealed that Gray was once romantically involved with Aki.
