* TheDanza: Sort of. Michi (AKA: "Trixie") was voiced by '''Michi'''ko Nomura.[[note]]Who was actually the second voice of Michi (beginning with episode 5 onwards), but is the most well known one.[[/note]]
* ExecutiveMeddling: The 1997 remake. When it was failing to catch on with audiences and the ratings, the original director was fired, causing the production to be suddenly overhauled. Although [[TropesAreNotBad this might have been for the better]], it still failed to bring the ratings up and production ceased after the 34th episode, with 52 stories originally having been planned.
* ScrewedByTheLawyers: DiC's 2002 "Speed Racer X" dub of the aforementioned remake. It's unknown exactly how many episodes got dubbed, but only 13 managed to be aired before [[http://variety.com/2003/biz/news/dic-takes-speed-to-court-1117885056/ DiC wound up in a lawsuit against Speed Racer Enterprises, over who REALLY owned the US rights to Speed Racer]].
** LaserGuidedKarma: And now it turns out that Speed Racer Enterprises lost the license to the series in 2011, and had been exploiting the property without permission from [[{{Creator/Tatsunoko Production}} Tatsunoko]] and getting themselves into a lawsuit that resulted in Tatsunoko snatching the license from SRE, as a result Tatsunoko exclusively owns all Speed Racer intellectual property rights worldwide, and any licensing agreement must be made through the company.

*** And surprisingly [[https://www.animenewsnetwork.com/news/2015-07-25/funimation-licenses-speed-racer-noein-anime/.90893 the series is now licensed]] by Creator/{{Funimation}}
* WhatCouldHaveBeen: As mentioned above, ''Mach Go Go Go '97'' was meant to run for 52 episodes.

* BigNameFan: Internet celebrity Egoraptor/Arin Hanson has stated multiple times on ''WebVideo/GameGrumps'' that this is his all time favorite movie.
* BillingDisplacement: Roger Allam plays Royalton, the principle antagonist. So where is he on the poster cast list? Nowhere.
* BoxOfficeBomb: Budget, $120 million (not counting marketing costs), $200 million (counting them). Box office, $93,945,766.
* StarDerailingRole: This film basically hurt Emile Hirsch's future in Hollywood (especially after receiving much acclaim for his previous role in ''IntoTheWild''), along with Christina Ricci's career. The two have more or less disappeared into smaller projects (in Ricci's case) or gone into smaller roles (in Hirsch's case).
* {{StillbornFranchise}}/FranchiseKiller: Plans for a sequel were cancelled when this movie failed to perform. It also severely damaged the ''Speed Racer'' franchise as well.
* WhatCouldHaveBeen: Some of the people who were to work on the movie at certain points in the long, ''[[DevelopmentHell long]]'' pre-production stage: Music/HenryRollins and Creator/VinceVaughn were both cast as Racer X. Creator/JohnnyDepp was hired to play Speed himself. Creator/GusVanSant and Creator/AlfonsoCuaron were both attached to direct. Creator/JJAbrams was hired at one point to write the script.
** Joel Silver said that the Wachowskis wanted to do the sequel in 3D. Alas, [[FranchiseKiller the film didn't make enough money to justify a sequel]].
* The actors who play Rex Racer and Racer X (Scott Porter and Matthew Fox, respectively) have the same birthday.
