Continuity mistake: When Gray is being operated on by Aki (he's on the medical table) you can clearly see a reddish-brown scar on the lower left side of his neck (it's not a recent wound). It appears off and on for the rest of the film. Example: you can not see it when they are conversing after escaping to space in her ship after everyone else dies.

Final Fantasy: The Spirits Within (2001)
Ending / spoiler
Directed by: Motonori Sakakibara, Hironobu Sakaguchi
Starring: Alec Baldwin, Steve Buscemi, Ving Rhames, Ming-Na Wen
Genres: Action, Adventure, Animated, Fantasy, Sci-fi, Thriller
Gaia is the life force of the planet that gives creatures on the planet life. Every living creature has this spirit inside it, including humans. The researchers discover the 7th spirit is any phantom spirit that comes in contact with Gaia. Therefore, the phantom virus within Aki automatically becomes the final spirit since it is already in direct contact with her spirit, and the wave is complete. Gray sacrafices himself in order to transmit the completed wave into the alien life-stream, which eliminates the phantoms, and saves the world.

Trivia: The first major animated feature film that attempted to create "photorealistic" characters. The studio had the intention of reusing the character models in different films as "digital actors," where they could "play" different parts like a real actor. However, the film underperformed at the box office and this idea was quietly dropped.
Question: The phantoms can kill with the merest touch and can reach through any material - floors, walls, aircraft fuselage etc. Why then do the soldiers bother to don heavy, clunky body armour whenever they go out to battle? They'd do just as well in T-shirts and fatigues.





Chosen answer: The environment has become too hazardous for humans to tolerate.
