Germans Love David Hasselhoff: While not exactly obscure in Japan, Mach GoGoGo is mostly known there for being popular in America. The original series' ratings averaged around 13-14% in Japan, which sounds impressive at first but was more along the lines of average for an anime series in that era. In fact, even the Japanese dub of the live-action film kept the American title and names of the characters and the 1997 remake was mainly made with the intention of dubbing it overseas.
The GRX from "The Fastest Car In The World" has a top speed of 250 mph and requires drivers to take a special drug to handle the speed. 250 mph is the approximate top speed of the Bugatti Veyron which has been driven that fast without any ill effects. In fact, when it was first shown on Top Gear, the presenter who first took it to said top speed was James "Captain Slow" May.
Everyone has parodied how every character in the show is a Motor Mouth.
In The '90s (during its Newbie Boom) it was popular for kids to say "Go Eraser! Go Eraser! Go Eraser GOOOO!" with chalk/whiteboard erasers.
While it's likely more a case of exaggeration, the abundance of pronounced gasping, "Aahh!" and "Ooohh!" sounds characters sometimes make at the end of their sentences have become memes in their own right, usually when reading out something with no punctuation, such as in this video.
In Race for Life, Speed just won a South American Grand Prix cup and is being serenaded with flamenco music and a dancer. Right after a brief comment with no animation from him, hellish screaming ensues as it cuts back to the dancer.. and just lingers on her for the next couple seconds as if no one heard it. It's hard to tell if it was a horribly misfire on dubbing a flamenco shout as agonized terror, or if it's the crowd reacting to a wounded José stumbling into the scene and everyone inexplicably has a huge Delayed Reaction.
Subbing vs. Dubbing: Many people actually prefer the dub because, well, a lot of people grew up on it and it has its Narm Charm from being made in the 60s.
Tear Jerker: The very fact that the Racer family, while happy and tight knit, is incomplete, given that the oldest brother Rex ran off years earlier after a fight with Pops. To make it worse, Rex actually wants to go home, but because of his involvement with secret organizations and crime-fighting, he can't.
From "The Most Dangerous Race" three-parter, Speed crashes into a ravine and wakes up temporarily blind from the sun-exposure. As he struggles to find the Mach 5, Snake Oiler arrives to gloat over his anticipated victory and Speed's misfortune. For a brief moment, Speed actually cries, either for a devastating loss, the feeling he'll never get help, or both. Thankfully, he powers through with the help of Racer X.
The "ninjas" were changed to "Assassins" in the dub. Which is actually correct, given their role in history.
Also while it did have renames, cut scenes and so on, it was one of the very first anime imports that tried to keep the spirit of the original show as faithfully as possible.
What Do You Mean, It's for Kids?: People die in this series on a regular basis, and while there's no gore or explicit blood, it doesn't even attempt to disguise how horrible some of the wrecks and incidents are, nor disguises things like villains plummeting off cliffs and real guns shooting people quite a lot. No one dances around the subject matter either, which makes it all the more jarring to realize that an entire generation of kids were raised on a series that puts more controversial cartoons like Tom and Jerry to shame. Today's audiences consequently suffer a case of Values Dissonance when they look back on this and realize just how dark such an over-the-top and corny series can be thanks to its shonen roots.
Awesome Music: The whole soundtrack, but especially Reboot, played during the final race in which Speed restarts his car from being burned out during the race and comes from dead last to first place. The track combines and recreates old pieces of the original Speed Racer soundtrack with a more modern and high-tech feel, with a bit of chorus in the background, culminating in the perfect musical accompaniment for Speed's main Moment of Awesome.
Better Than Canon: Minor example, but this fan edit replaces the song that plays during the climactic final race with The Top from Initial D. It's near-universally considered a massive improvement.
Speed's infamous "Get that weakshitoff my track!" line during his battle with Cannonball Taylor has become a somewhat popular catchphrase in the racing game and sim communities.
A fanmade edit of the grand finale race with the Eurobeat track "The Top" neatly dropped into the sequence became quite memetically popular in the fandom in general. Bonus points for the vocals (and the theme of the song in general) matching up perfectly and syncing to the scene.
Misaimed Marketing: The advertising blundered just enough to make a difference. It appeared to be a purely badass action movie with eye-popping inventive visuals. It turned out to have a more childish tone, in keeping with the anime. The advertising also downplayed the presence of Spritle and played up the presence of Christina Ricci.
Snake Oiler is one of the whiniest and most annoying villains to appear onscreen. Though granted, that's likely the point.
Spritle and Chim-Chim aren't exactly popular to some fans, as they take up a lot of the movie's time with juvenile comic relief scenes.
Signature Scene: The final race, where, through sheer determination, Speed races all the way to first at the speed of a jet plane, grapples two racers so that they crash into each other, and basically give the laws of physics the finger.
So Bad, It's Good: Be it design or accident, it's a damn awesome movie if you're in the right mindset.
The family watching Rex's FaceHeel Turn and subsequent death. Even knowing what will probably happen as a result of knowing the cartoon, watching the family deal with this is downright heartbreaking.
Few people with a sibling can avoid Inelegant Blubbering or at the very leastManly Tears when Speed lets his foot off the gas to let his dead brother's lap record stand.
Nearer the end of the film, John Goodman's Pops is heartbreakingly sincere as he refuses to make the same mistake he did with Rex, assuring Speed that he will always love him and welcome him home no matter what.
The scene in the end where we see the truth about Racer X's identity; he truly is Rex, having faked his death and undergone plastic surgery in order to disguise his true identity to protect Speed and his family. Made all the more heart-wrenching by Rex's decision to not reveal the truth to his family, saying it's a mistake he will have to live with.The score during the moment only adds to the waterworks.
