Fast and Furious, also known as F&F 4 to avoid confusion with the first movie, is the fourth film in the series. Acting as something of a Soft Reboot of the franchise after Tokyo Drift under preformed. Released in Spring 2009 with Diesel, Walker, Michelle Rodriguez, Jordana Brewster and Sung Kang reprising their previous roles.
It's been five years and Brian has returned to Los Angeles law enforcement, this time as an FBI agent hunting another drug dealer. Meanwhile, Dom has left his crew, only to get thrust into the world of racing once again when his girlfriend, Letty, is killed while working undercover for the same drug dealer. Brian reunites with Dom, offering him a pardon in exchange for help catching the drug dealer. However, tension heats up when their personal motivations are revealed as Brian, Dom, and Mia struggle to work through the residual complications of their last encounter with each other.
Chronologically it's set after 2 Fast 2 Furious with Fast Five proceeding it.
- Action Film, Quiet Drama Scene: Brian explaining himself after it emerges that Letty was his informant.
- Arson, Murder, and Jaywalking: Not explicitly depicted but the judge is all too happy to throw the book at Toretto, sentencing him to a life term of which he must serve at least 25 years.
- Author Appeal: Although he isn't a big car guy, director Justin Lin expressed his appreciation for the Buick GNX, and urged the car coordinators to have Dom drive one at the start of the movie as it fit his character and because it had barely been used in movies.
- Awesomeness by Analysis: Dom shows incredible detective prowess, instantly knowing not only exactly what went down at Letty's crash site, but walked out with a vital clue apparently even the FBI missed.
- Back from the Dead: You know that 1970 Dodge Charger (which was wrecked by his father and rebuilt before the first film's events) that Dom wrecks in the first film? It's back in this film. And it gets wrecked and rebuilt again.
- The movie begins with Dom and his gang hijacking an oil truck and ends with him getting rescued by Brian, Mia and his gang from the beginning. Also counts as a Bolivian Army Ending.
- Also invoked with Fenix. Earlier in the movie Dom sees Fenix standing over Letty before killing her in some sort of guilt induced hallucination. At the end, Fenix stands over Brian in much the same way before Dom swoops in for the rescue.
- Chekhov's Gun: During the initial U.S. - Mexico border run, Dom notices several propane tanks in the tunnels. Later on, he uses this to kill one of Braga's henchmen.
- Darker and Edgier: Fast & Furious compared to the other films. It has a much grimmer atmosphere with both Brian and Dom investigating who was behind Letty's (apparent) death and Dom personally seeking revenge.
- Dropped A Bridge On Her: Letty has all of five minutes of screentime, and the next thing we know, Mia calls up Dom to tell him that Letty has been killed by Fenix. We get to see what happens later, at least, but it's still awkward, especially since Michelle Rodriguez has her name on the posters.
- Extreme Sport Excuse Plot: Excuse is same as the second film (undercover cop and an ex-convict become street racers in order to get hired as drivers for a drug lord so they can infiltrate his operation) and the added twist that Dom is also going undercover on his own initiative to get revenge on the man who killed his girlfriend.
- Fanservice: The film has moments of hot girls kissing during club scenes.
- First Girl Wins: Mia for Brian.
- High-Altitude Interrogation: Dom does this to one of Braga's informants.
- The Man in Front of the Man: The front man for the drug running ring appears to be working for an unseen boss. The boss turns out to be a decoy and the front man is the actual boss and Big Bad.
- Only a Flesh Wound: A mook shoots Dom directly in his shoulder. The look on Dom's face made it clear he was more worried about his nice jacket than any damage done to his actual person. Oh, and Dom proceeds to beat the mook damn near to death, with both hands. And doesn't so much as flinch while Mia patches up the wound.
- Outrun the Fireball: Dom when the propane tanks in the tunnel explode. Also inverted at the beginning, where Dom runs towards the fireball.
- Product Placement: Subaru donated the Impreza WRX STIs.
- Reality Ensues:
- Dom and Mia don't trust Brian for betraying their trust in the first film and it takes almost half the movie for them to forgive him and start trusting him again.
- Despite helping to arrest a wanted drug lord and aiding a federal agent, Dom is arrested and sentenced to 25 years to life for his previous crimes. Thankfully, Mia, Leo and Santos, and Brian get ready to break him out...
- Real Men Wear Pink: Subverted. The fact that Braga, a man who supposedly clawed his way up from "varrio enforcer" to "ruthless drug kingpin", came to a drug deal wearing a salmon pink silk tie is immediately taken by Dom and Brian as evidence that the man is not the real Braga.
- Secret Underground Passage: Braga's men use a hidden tunnel wide enough to drive through to smuggle drugs across the US Mexico border.
- Sequel Hook: Dom's escape from the prison bus, revealed at the beginning of Fast Five.
- Tempting Fate: Brian and Dom kidnap Braga in order to forcibly take him back to the United States.Brian: Where your boys at? Huh? They gonna show up, or what?(Braga's men come swarming in from everywhere)Braga: Careful what you ask for!
- That's What I Would Do: Brian tries to narrow down a list of suspects with the same name to figure out which one is involved with street racing. He has his FBI partner read off a list of the suspects' cars. After hearing about a Nissan 240SX with an illegal modification, he remarks that he's the one. His partner asks how he knows this and he replies "Because that's what I'd drive."
- Third-Person Person: Dwight.Dwight: Dwight likes this foot a lot.
- Trailers Always Lie: Mia driving in the trailer. She only drives at the very end, a minute before the credits.
- Unresolved Sexual Tension: When Brian and Mia see each other again, Mia hadn't yet forgiven him for his role as an undercover cop five years earlier. Naturally, this is followed by They Do.
