Trivia / Mazinger Z: Infinity

• Actor Allusion: Also counting as a Casting Gag. This is not the first time Mike Pollock has voiced a mad scientist aiming for world domination with an army of robots.
• Author's Saving Throw: Associate director Nakano Yuu gave an explanation why they didn't mention UFO Robo Grendizer in the movie while confirming that it's actually still part of the history of Mazinger Z: Infinity instead of throwing it to Canon Discontinuity: He and the team predicted that if they ever mentioned things from Grendizer and yet didn't have the mecha itself appear on-screen, the audience would be disappointed, so to avoid such case, they just decided not to mention it at all.
• Big-Lipped Alligator Moment: A flashback of Tetsuya slapping Jun.
• Cowboy BeBop at His Computer: When it was first announced, several articles incorrectly referred to the film as a live action adaptation.
• Celebrity Voice Actor: The male half of Baron Ashura is voiced by Hiroyuki Miyasako, who is best known for playing the boke in the comedy duo Ameagari Kesshitai, and he is often involved in high-budget japanese movies.
  • Likewise, two of the Mazin Girls are voiced by Yui P and Okarina who are both part of the comedy duo Okazu Club.
• Referenced by...: This movie made its debut to the Super Robot Wars franchise in Super Robot Wars X-Ω as a one-time event before its normal debut at Super Robot Wars T. Amongst the good modifications to the story, it massively reduced Tetsuya's tenure as the Badass in Distress into only 1-2 scenarios, and it brought back references to UFO Robo Grendizer within the timeline in the game story context without name-mentioning, since they had more time and this cross-series reference practice has been pretty common in Super Robot Wars series.
  • In its return appearance in Super Robot Wars 30, the Infinitism version of Mazinkaiser was also added in.
• Real-Life Relative: Tetsuya and Jun's voice actors in the Latin American Spanish dub, Arturo Mercado Jr. and Diana Galvan Santos respectively, are married in Real Life, just like their characters in-film.
• Role Reprise: The Latin American Spanish dub brings back almost all the voice cast from the remasterized version of the original series, being the sole exception Shiro, since he is now older, and as such he is voiced by a male voice actor (Alberto Bernal), rather than a female (Susana Moreno).
