Author Existence Failure: Some people might at least consider the film's use of incredibly realistic CGI to be the cornerstone for an Award Snub for Best Visual Effects. However, it couldn't have won any awards; Square Pictures was disbanded before the Oscars that year.
Box Office Bomb: Budget, $135-167 million. Box office, $85,131,830. Lost over $100 million. One of the reasons why Square Pictures was discontinued...
Celebrity Voice Actor: Alec Baldwin as Gray, Donald Sutherland as Cid, James Woods as General Hein and Steve Buscemi as Neil.
Actually didn't actually force Square's merger with Enix (in fact, it delayed it).
Inspired By: The technological aesthetics of Mass Effect's human armor and omni-tools were lifted from The Spirits Within, as the game's art director was a fan of the movie's style. Ironic, considering shortly after the release of Mass Effect 2, in a PR move, Bioware executives publicly dissed the Final Fantasy franchise.
No Flow in CGI: Aki's hair is a deliberate aversion of this trope, and there are plenty of shots where she just flips her hair about to show it off. Elsewhere it's played straight by the council woman having Power Hair, and Jane's being short and tied up (although being in the military, she'd be required to have it tied back anyway).
In early drafts of the script, Aki was Cid's granddaughter. In the final film, they are just co-workers.
Characters were dropped from the script as it kept changing. The Deep Eyes would have had a fifth squad member called Robert. A smaller girl called Meg would have had a larger role, but the only reference to her in the final film is Aki saying she had to draw the fifth spirit from a terminally ill child.
