Hobbs, being played by former WWE champion Dwayne "The Rock" Johnson, gets to bust out a few wrestling movies - he pulls off a Doomsday Device with Dom in 6, and hits the Rock Bottom, his WWE finishing move, in Furious 7.
Paul Walker's preference of Japanese imports in real life is reflected on Brian. In fact, the Nissan Skyline R34 GT-R from 2 Fast 2 Furious and the Toyota Supra from Furious 7 are his personal vehicles.
Martial artist henchman Jah has half of the name of another character also played by Joe Taslim, Jaka.
Author Existence Failure: Paul Walker was killed in a car accident over Thanksgiving weekend 2013, which unfortunately happened while Fast & Furious 7 was still in production.
The first movie is best known as a Vin Diesel flick. Paul Walker actually plays the main character. Downplayed example, as Vin Diesel's character is just as critical as Walker's. It's also worth noting that in the more recent films, especially 5 and 6, Dom actually does fit the main character role more than Brian by this point.
The fourth movie prominently features Michelle Rodriguez on the poster and in the trailers, even though her character dies roughly fifteen minutes into the movie. Then subverted when she returns in the sixth film and is the only main character to not get featured on its poster.
Breakaway Pop Hit: Not many $1 billion grossing movies can claim to have spawned a hit song bigger than the film itself: Furious 7 can, thanks to Wiz Khalifa's "See You Again." It reached the point where "See You Again" became the only thing related to Furious 7 to get a Kids' Choice Awards nomination in 2016.
Cash Cow Franchise: Oh, so much, especially Furious 7; it grossed $1 billion worldwide by the end of its' first weekend in domestic release.
Creator Cameo: Rob Cohen makes a brief cameo in the first film as a Pizza Hut deliveryman.
Tokyo Drift is the biggest offender, for obvious reasons: Lucas Black (Sean) was 22, Zachary Ty Brian (Clay) was 23, Nikki Griffin (Clay's girlfriend Cindy) was 28, Nathalie Kelley (Neela) was 21, Bow Wow (Twinkie) was 19, Leonardo Nam (Takeshi's friend Morimoto) was 25, and Brian Tee (Takeshi) was the worst at 29. Only Bow Wow was still technically a teenager out of the cast.
The trope is even more in effect in Furious 7, which finally gets to the timeline of Tokyo Drift. Lucas Black, now 32, returned to play his unaged character (Nathalie Kelley and Bow Wow appeared through archive footage only).
Both Toretto (Vin Diesel) and Vince (Matt Schulze) were said to be 24 when The Fast and The Furious has been made. Vin Diesel was 34, Matt Schulze was 29 by then.
Well, Schulze was still in his twenties at least. Diesel, however, passed pretty well for 24-year old Toretto. (Many have jokingly attributed Diesel's younger appearance compared to his real age to his love for Dungeons & Dragons.) However, the actors for Tokyo Drift easily stand out as people older than their character's ages, Dawson Casting at it's damn-near worst.
Sung Kang was 40, 38, 36 and 34 respectively when filming Fast & Furious 6, Fast Five, Fast and Furious and Tokyo Drift. Granted, we wouldn't be able to pinpoint Han's actual age in the films, but it's freaking amazing how Kang manages to pull off the role looking young.
Doing It for the Art: Subverted. Supposedly, Vin Diesel's cameo in Tokyo Drift was done in lieu of payment, but in exchange for the rights to the Riddick series.
Dueling-Stars Movie: Fast Five is most notable for being Vin Diesel vs. Dwayne Johnson. Johnson's character was originally going to be an older guy, but awesomely enough the filmmakers took up a fan's suggestion on Facebook that it would be great to see Diesel and Johnson in a movie together. And The Stinger for #6 hints that they're taking it up a notch by adding Jason Statham.
Fake Ethnicity/Fake Nationality: Italian-American Dominic Toretto is played by Vin Diesel, who is biracial of many ancestries (including English, German, and Scottish) but Italian isn't one of them. His sister, Mia, meanwhile, is played by Jordana Brewster, who is of Brazilian and English descents.
Johnny Tran is possibly Vietnamese-American, judging by his name, but his actor is Rick Yune, an American of Korean descent. Meanwhile, his cousin, Lance Nguyen, is played by the Filipino-American Reggie Lee.
Another interchangeable Asian example: Morimoto, from Tokyo Drift, is Japanese, but is played by Leonardo Nam, an Argentine of, again, Korean descent.
Brazilian Officer Elena Neves is played by Elsa Pataky, a Spaniard.
Fast & Furious 6Big Bad Owen Shaw is Irish, but his actor, Luke Evans, is Welsh. Then there's his brother, Deckard, in Furious 7, played by Englishman Jason Statham.
Fan Nickname: Tokyo Drift was seen on actual theatre marquees as "3 Fast 3 Furious." Despite this phrase making negative amounts of sense, everyone knew what film it was referring to.
Market-Based Title: Many foreign countries have regular Numbered Sequels instead of the word removal - only "Fast" or "Furious" - they got in English (at times with The Foreign Subtitle - for instance, Fast Five is known in many countries as Fast and Furious 5: Rio Heist). Likewise, Furious 7 is known as just Fast and Furious 7. However, all the films in the series so far has been released in Japan under the title Wild Speed instead.
The stuffy British guy in Furious 6 was apparently supposed to say "You're clearly not a player" to Tej and Hobbs, but the actor ad-libbed "you're clearly not a baller." This change cracked everyone up enough that it was left in.
At the end of 6, there is an exchange between Roman (Tyrese Gibson) and Hobbs (Dwayne Johnson) at the Toretto home. Roman says, "Hey Mia, better hide your baby oil!" to which Hobbs responds, "...You better hide that big-ass forehead!" The latter line was unscripted, and the delivery caused Tej (Chris Bridges) to spit out his beer in laughter. This take was used in the final cut.
The role of Mia was originally written for Eliza Dushku, who turned it down.
The fifth film actually started out as The Brazilian Job, the proposed sequel to The Italian Job, when the sequel went through Development Hell, the script was bought and rewritten to fit into the F&F series.
Certain versions of the DVD, as well as Blu-Ray copies of the original have what was going to be an alternate ending. Brian is dropped off at the Toretto home, now for sale, to find Mia packing up the garage. Mia tells him to go, before Brian reveals he quit his job as a cop and was hoping for one more chance, before cutting to a wide shot of LA. Given how the following sequel paints Brian as running away to Miami for a new start, it would have been interesting to see the current films if the alternate ending was used.
Michelle Rodriguez & Jordana Brewster didn't have driving licences when they were first cast in the original film; they had one shot to pass their tests, and if they didn't, their roles would have been recast.
While part seven was in production, Universal hoped to get to at least ten movies, and Furious 7 would even have another Sequel Hook to widen the series' scope. Then Paul Walker died, and the movie had to be rewritten to give some sort of closure, particularly to Walker's character Brian.
The song that plays in Furious 7's final scene, "See You Again", was originally supposed to be sung by Sam Smith rather than Charlie Puth.
Deckard Shaw was originally to be named Ian Shaw. This was changed to avoid confusion with his similarly-named brother, Owen Shaw.
