!!Series
* TheDanza: Sort of. From episode 5 on, Michi (AKA: "Trixie") was voiced by '''Michi'''ko Nomura.
* LimitedSpecialCollectorsUltimateEdition: The only way to get ''Mach Go Go Go'' subtitled (as the incomplete fansub project ceased once Funimation's license was announced) or the 1997 remake, as Funimation is only streaming the dub. The case is shaped like Speed's head.
* ScrewedByTheLawyers:
** Speed Racer Enterprises' rights to ''Speed Racer'' expired in 2011. Creator/TatsunokoProduction sued SRE for exploiting their rights without their consent in October 2012. When the lawsuits were dismissed in December 2013, the ''Speed Racer'' intellectual property rights were reverted to Tatsunoko, and any licensing agreement must be made through the company. [[http://www.animenewsnetwork.com/news/2014-01-04/speed-racer-rights-revert-to-tatsunoko-with-lawsuit-settled You can read more about it here]].
** And surprisingly, in July 2015, [[https://www.animenewsnetwork.com/news/2015-07-25/funimation-licenses-speed-racer-noein-anime/.90893 the series was licensed]] by Creator/{{Funimation}}, which re-released the English version in 2017 and plans to bring out the subtitled Japanese version for the first time in North America.
*** And also because of the legal issues surrounding the dub of the 1997 remake, Funimation's release of said remake won't include the English dub and will be available with subtitles only.
** Because of this, all Western comic book adaptations of the franchise are out of print, with Digital Manga continuing to publish the original manga, as its publication involved directly working with Tatsunoko.
* StarMakingRole: This was Katsuji Mori's first major role into voice acting.

!!Film
* BillingDisplacement: Roger Allam plays Royalton, the [[BigBad principal antagonist]]. So where is he on the poster cast list? Nowhere.
* BoxOfficeBomb: It had a $120 million budget (with an added $80 million in marketing costs), and only managed $93 million in box office totals.
* CelebrityVoiceActor: In the Japanese dub, Speed Racer and Trixie are voiced by Jin Akanishi and Aya Ueto.
%%* DyeingForYourArt:
* MultipleLanguagesSameVoiceActor: Benno Fürmann reprised his role as Inspector Detector for the German-language release.
* PromotedFanboy: Creator/MichaelGiacchino was a fan of the original anime series as a child and he incorporated Nobuyoshi Koshibe's main theme when he scored the film. Emile Hirsch was also a big fan.
* RealLifeRelative: In the Latin American Spanish dub:
** Creator/ArturoMercadoJr (Sparky) is the son of Creator/ArturoMercado (Tetsuo Togokhan) as well as the cousin of Erica Edwards (Horuko Togokhan).
** Andrea Coto, who plays Mom Racer, is the mother of Sergio Gutiérrez Coto, who voices Inspector Detector.
* RecycledSoundtrack: Stock Creator/HannaBarbera musical cues (first used in ''WesternAnimation/JonnyQuest'') are reused in the anime scene.
* RoleReprise: Emile Hirsch, Christina Ricci and Matthew Fox reprised their roles for the tie-in game.
* SavedFromDevelopmentHell:
** In September 1992, it was announced that Creator/WarnerBros held the option to make a live-action ''Speed Racer'' film to be developed at Silver Pictures. In October 1994, Music/HenryRollins was offered the lead role. In June 1995, Creator/JohnnyDepp was cast with Creator/JulienTemple directing, with production slated to begin the coming October, with filming to take place in California and Arizona. The following August, Depp requested time off for personal business, delaying production. However, due to an overly high budget, Temple left the project the same month and Depp followed suit. The studio considered Creator/GusVanSant as a replacement, though it would not grant him writing privileges. In December 1997, the studio briefly hired Creator/AlfonsoCuaron as director. In the various incarnations of the project, screenwriters Marc Levin, Jennifer Flackett, Creator/JJAbrams, and Patrick Read Johnson had been hired to write scripts.
** In September 2000, the studio and producer Lauren Shuler Donner hired music video director Hype Williams to direct. In October 2001, screenwriters Christian Gudegast and Paul Scheuring were hired for $1.2 million split between them to write the script. Eventually, without production getting under way, the director and the writers left the project.
** In June 2004, Creator/VinceVaughn spearheaded a revival by presenting a take for the film that would develop the characters more strongly, with himself playing Racer X as well as serving as executive producer. With production never becoming active, Vaughn was eventually detached from the project.
** Creator/TheWachowskis came aboard in October 2006, production began in Summer 2007 and the film was finally released in 2008.
* SequelInAnotherMedium: The video game adaptation is set one year after the film's events.
* StarDerailingRole:
** This film hurt Creator/EmileHirsch's future in Hollywood (especially after receiving much acclaim for his previous role in ''Film/IntoTheWild''). He went into smaller roles for most of the 2010s, though he did bounce back a bit when he replaced his late friend Creator/AntonYelchin as the voice of Jim in ''WesternAnimation/{{Trollhunters}}'' and managed to be part of the ensemble cast of ''Film/OnceUponATimeInHollywood''. The assault charges he pled guilty to in 2015 didn't help matters either.
** Christina Ricci disappeared from mainstream roles for a while afterwards, though she was still doing quite well in independent films. After attempting CareerResurrection with ''Series/ZTheBeginningOfEverything'' (which she produced), she finally achieved it with ''{{Series/Yellowjackets}}''.
* StillbornFranchise: Joel Silver said that Creator/TheWachowskis wanted to do the sequel in 3D. Alas, the film didn't make enough money to justify a sequel. Emile Hirsch tried to gain support for the sequel online in 2018, in the hopes that the film's cult fan base might justify it.
* VoiceOnlyCameo: Corrine Orr, the original Trixie, has a voice-only role as the Grand Prix's English announcer.
* WhatCouldHaveBeen:
** Creator/ShiaLaBeouf, Creator/JosephGordonLevitt and Creator/ZacEfron were considered for Speed Racer.
** Creator/ElishaCuthbert, Creator/KateMara and Creator/RoseMcGowan were considered for Trixie.
** Creator/KeanuReeves turned down the role of Racer X.
** Racecar driver Danica Patrick was offered a cameo, but had to turn it down due to other commitments.
** As indicated in an earlier draft of the script, E.P. Arnold Royalton's last name was originally named Remmington.

!!General Trivia:
* The actors who play Rex Racer and Racer X (Scott Porter and Matthew Fox, respectively) have the same birthday.
