Final Fantasy VII: Advent Children/Trivia

• Casting Gag: The voice actress for Marlene in both Japanese and English (Sumire Morohoshi and Ariel Winter, respectively) shares the voice for characters in other Square Enix works: Mog and young Kairi, who are also cute, small characters. Andrea Bowen, who played the Moogle Girl, was also upgraded to voicing Aerith in Crisis Core.
• Celebrity Voice Actor:
  • Japanese: Ayumi Ito as Tifa
  • English:
    • Steve Burton as Cloud
    • Rachael Leigh Cook as Tifa
    • Christy Carlson Romano as Yuffie Kisaragi
    • Mena Suvari as Aerith Gainsborough
    • George Newbern as Sephiroth
• Development Hell: The original movie was announced at Tokyo Games Show 2003, and wasn't released in Japan until late 2005, due to significant changes to the script during early development. Complete was announced at TGS 2006, and would subsequently not be released until March 2009.
• Fan Nickname: Kadaj, Yazoo and Loz were colloquially referred to as the SHM (Silver-Haired Men) in fan forums before their official names were made public, and sometimes still are.
• Hey, It's That Voice!:
  • Yuffie is Kim Possible, Cloud is Jason Morgan, Sephiroth is Superman, Kadaj is Kamui, Yazoo is Kakashi, and Reno is Axel.
  • Justified with the last, as the developers of Kingdom Hearts actually set out to make Axel an Expy of Reno.
  • Sephiroth is that Superman?! That makes Crisis Core even more believable!!
• No Export for You: Complete's vocal theme, "Safe and Sound," is not in Western releases of the film, which is odd considering that the song is written by Gerard Way from My Chemical Romance and sung entirely in English . Furthermore, it's only available on the Japanese iTunes. "Calling" from the original version was used for the Western release.
• The Other Darrin: George Newbern took over for Lance Bass as Sephiroth starting with this movie. For the Complete version, Aarom Refvem and Ariel Winter replaced Benjamin Bryan and Grace Rolek's Denzel and Marlene since the latter two actors grew up and couldn't voice them for the new scenes. Mandy Moore had also voiced Aerith in the first Kingdom Hearts game but was replaced by Mena Suvari for this one.
• Sure Why Not: The producers of this film openly admitted that they turned Cloud from the serious hero into the brooding loner because the "fans" would be familiar with this image of him.
• What Could Have Been: At a very early stage in development, the only featured characters were going to be Cloud, Tifa, Kadaj and Sephiroth. The run-time was also planned to be far lower than in the final movie; early interviews mentioned around the 40 minute mark. This would change as it became apparent that fans were expecting much more than the initial script apparently had, prompting a fairly extensive rewrite. The TGS 2003 trailer, and the unused footage it contains, probably comprises the remains of that early version of the movie.
  • The initial choice for Denzel's seiyuu was Koki Uchiyama. However, he was a bit too old to fit the bill, but Nomura later used him in Kingdom Hearts II as the voice of Roxas and later in Kingdom Hearts: Birth by Sleep as Ventus.
