Trivia / Justice League vs. The Fatal Five

• Creator's Favorite: According to Eric Carrasco, his favorite Legionnaire is Star Boy and his favorite Green Lantern is Jessica Cruz, which is why they were chosen for this movie.
• Flip-Flop of God:
  • The movie's status as a DCAU entry is this. Sam Liu has mentioned that this is a project more in spirit to the DCAU rather than actually being in it. Bruce Timm himself would later confirm the canonicity, stating it takes place sometime after Justice League Unlimited. However, he also stated in the audio commentary for the film that due to the film being changed to a JLU type movie during post production, there would inevitably be some continuity issues. Ultimately, he said fans could decide on their own, and that he's a "firm believer in head-canon."
  • Several large contradictions to the DCAU:
    • Miss Martian is a supporting character in the film, yet in the DCAU, J'onn J'onzz the Martian Manhunter is the last of his kind, which was also a large part of his character in the series. Miss Martian shouldn't exist in this continuity, and even if this is a retcon, no explanation is given as to how she can suddenly exist.
    • In the Justice League Unlimited episode "Far From Home", the Fatal Five is introduced and Supergirl stays in the future with Brainiac 5 and rest of the Legion of Superheroes. This film unfolds as if that episode never happened. Supergirl is never mentioned, even when Brainiac 5 appears at the end of the film in the 21st century with the rest of the legion. Superman also acts as if he's never heard of the Legion of Superheroes or the 31st century, even though he was aware of his cousin's whereabouts, and was presumably told of the rest of the adventure in "Far From Home" by Green Arrow or John Stewart.
    • Hal Jordan is shown as one of the Green Lantern's of the Earth sector, yet there never was a Hal Jordan who became a Green Lantern in the DCAU, only appearing in an alternate timeline. When asked about Hal Jordan's existence in the DCAU, the late Dwayne McDuffie answered on his website that he was of the opinion that Hal was a Green Lantern in a universe where John wasn't and is probably still a test pilot in the main universe, as implied in "The Once and Future Thing, Part 2".
• Role Reprise:
  • Kevin Conroy, Susan Eisenberg, and George Newbern reprise their respective roles as Batman, Wonder Woman, and Superman.
  • Kevin Michael Richardson reprises his role as Kilowog from the Green Lantern: Rise of the Manhunters video game and Green Lantern: The Animated Series. Tom Kenny also reprises his role from the latter as Salaak.
• Sequel Gap: This is the first work based on Justice League Unlimited, since the series ended in 2006, nearly 13 years prior.
• Throw It In!: According to Eric Carrasco, the script didn't specify which Green Lanterns were in the museum, so it was left to the artists and animators who to put in.
• What Could Have Been:
  • Bruce Timm originally wanted to use the character designs from Justice League: Crisis on Two Earths and Justice League: Doom, but James Tucker convinced him to use the JLU designs.
  • There was going to be a tie-in comic like with Batman and Harley Quinn, but it was cancelled according to Eric Carrasco in an interview with Watchtower Database. Apparently, the comic would have addressed Miss Martian's origins. It also would have covered J'onn, Shayera, and John on Thanagar and Rann.
