The Danza: Sort of. From episode 5 on, Michi (AKA: "Trixie") was voiced by Michiko Nomura.
Limited Special Collector's Ultimate Edition: 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.
Screwed by the Lawyers: Speed Racer Enterprises' rights to Speed Racer expired in 2011. Tatsunoko Production 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. You can read more about it here.
And surprisingly, in July 2015, the series was licensed by 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.
Promoted Fanboy: Composer Michael Giacchino 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.
Star-Derailing Role: This film basically hurt Emile Hirsch's future in Hollywood (especially after receiving much acclaim for his previous role in Into the Wild), 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, though he did bounce back a bit when he replaced his late friend Anton Yelchin as the voice of Jim in Trollhunters).
