In the Mexican Spanish dub, Cid is voiced by Mexican soap opera actor Hector Bonilla.
Creator Killer: The film's bombing is commonly cited as the reason Hironobu Sakaguchi resigned from Square.
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.
