When the crew is shown the garage of all of the cars including the army tank, you can see Paul Walker's GTR that his character drove in Furious 7 (2015) up on top of one of the three-tier car racks. A subtle tribute to the late actor.

A week before filming ended, Dwayne Johnson posted an infamous message on Instagram, confirming that the production had endured its share of on-set frictions: "This is my final week of shooting #FastAndFurious8. There's no other series that gets my blood boiling more than this one. An incredible hard working crew. Universal has been great partners as well. My female co-stars are always amazing and I love 'em. My male co-stars however are a different story. Some conduct themselves as stand up men and true professionals, while others don't. The ones that don't are too chicken shit to do anything about it anyway. Candy asses. When you watch this movie next April and it seems like I'm not acting in some of these scenes and my blood is legit boiling - you're right. Bottom line is it'll play great for the movie and fits this Hobbs character that's embedded in my DNA extremely well. The producer in me is happy about this part. Final week on Fast 8 and I'll finish strong. ;/ #IcemanCometh #F8 #ZeroToleranceForCandyAsses". The post came after co-star and executive producer Vin Diesel reportedly cancelled some of Johnson's planned scenes at the last minute. On several occasions, Diesel had also reportedly refused to show up on-set as he was scheduled, leaving hundreds of cast, crew, and extras waiting on-set for him for more than six hours. Diesel confronted Johnson in a secret meeting one day after Dwayne's message was posted on-line. Johnson later told The Hollywood Reporter that the meeting cleared up a few things. He confirmed that he and Diesel did not shoot scenes together because of "a fundamental difference in philosophies on how we approach filmmaking and collaborating", but that he was "grateful for that clarity". Although he did not provide details, it was later revealed that the announcement of Johnson's spin-off movie Fast & Furious Presents: Hobbs & Shaw (2019) was one of the main reasons for Diesel's behavior (as it would split up the series, and delay F9: The Fast Saga (2021)). Johnson stated that he would probably pass on Fast & Furious 9, but wished Diesel "all the best and I harbor no ill will there, just because of the clarity we have. Actually, you can erase that last part about 'no ill will.' We'll just keep it with the clarity".

Paul Walker's character, Brian O'Conner used to drive Japanese imports. His replacement, Little Nobody (Scott Eastwood), who was his close friend in real life, also drives these type of cars (Subaru BRZ and Subaru Impreza WRX STi) in this movie. This indicates a tribute to the late Paul Walker from Scott, as these types of cars were his favorite in the Fast and Furious films, as Brian O'Conner and in real life.

When Mr. Nobody (Kurt Russell) explains the "top 10 most wanted" list, and that Roman (Tyrese Gibson) was number 11, he says people in the room are numbers 6, 8, 9, and 10. The missing number 7 is a tribute to Paul Walker, who died during production of Furious 7 (2015). His character, Brian O'Conner, is now out of the line.

In one argument between Hobbs and Shaw, Dwayne Johnson decided to ad-lib and came up with a line about knocking Shaw's teeth so far down his throat, he'd need to stick a toothbrush up his ass to brush them. Jason Statham was so amused by the ad-lib that he broke character and started laughing. That's the take that was used in the film.

Continuity

After Dom is captured/lured to the side of Cipher, there's basically no time Dom can make arrangement for him to meet up with Shaw's mother, as well as having the two ex-crew to cover up his meeting with Shaw's mother and knowing all the blind spot in the meet up alley.

After Dom crashes through the flower stand, his black car is covered in flower petals and debris. In the next shot, the car is completely clean and undamaged.

In making his escape in the sub factory Vin Diesel's car smashes into and pushes an armored vehicle out of the way, smashing it into a building but his car emerges out of the dust and flames without a mark on the front.

After Roman's swim in the ice, his skin and clothes are dry.

The movie is set in its release year of 2017 a brand new Jeep Grand Cherokee is shown to have 1870 miles.



Factual errors

There is no way the Akula Class submarine could have come remotely close to keeping up with the vehicles on the surface, let alone overtaking them. Even though the Akula was rated as one of the fastest submarines in the world during the cold war, with a reported top speed of between 28-35 knots (32-40 mph) this would be far from what the cars and trucks were apparently doing speed-wise even IF the reported top speed was DOUBLE what has been reported at 70 knots (80 mph). The part where the submarine broaches (comes to the surface) and overtakes the vehicles WHILE cutting through the ice is comical as the Akula classes reported surface speed is 10-12 knots (11-13 mph). A knot is only a measurement of a nautical mile per hour which is equivalent to about 1.15 mph.

The heat-seeking missile launched at Dom would've hit Dom in a matter of seconds. The slowest heat-seeking missile, has a speed of Mach 2.5 which is a bit faster than a bullet. There is no way a car running on ice at approx 80 mph would've outrun a missile coming at him at 1,900 mph.

An EMP weapon does not produce a shock wave.

Dom drives against, and beats his competitor in reverse. Reverse gear Is similar ratio to that of a forward first gear. It would be impossible to drive a basic car in reverse and beat someone who is at max speed in a forward gear.

A submarine's propeller is made for propelling it through water, not air. Activating the engine while the submarine is propped up on land will not cause it to move.



Revealing mistakes

When Hobbs is in his cell, he repeatedly hits the concrete wall with his fists. It moves.

When Tej fires the Ripsaw machine gun, spent brass is shown hitting the ice. However, they are crimped at the end, revealing that they are blanks and not from live rounds.

When Tej pulls up a traffic cam feed of Rhodes, the feed appears before he hits the key on his keyboard.

In a scene where the crew is being chased on the ice, the camera slows down to show bullet casings flying by the camera for cinematic effect. You can clearly see the crimped edges of the casings, revealing they are blank cartridges.

With the whole team being wanted on interpol top eleven list, it's impossible that Brian O'Conner dint know about this.



Miscellaneous

After Dom rejoins his team as they are escaping Littke Nobody says "What is this guy on our side now?" to which Tej replies "Who the hell cares? He just saved our ass"- Little Nobody didn't use his walkie talkie though Tej replied through his despite the fact he could not have heard him.

when Vin jumps outside of his car at the end of the first race, the curb of the sidewalk and the hole of the sewer are very huge, as much as Vin! (VFX fault) The sky in this and the next shot are VFX composition and are too blue and dark, isn't believable...at the next shot, with the car jumping, has real sky, with more exposition.



Crew or equipment visible

just before Vin meets Charlize in front of a church, in the first shot of the sequence you can see a man with a tripod inside the church.



Errors in geography

Most of the streets seen in parts set in Manhattan are bidirectional, based on the road markings visible throughout. Nearly every major thoroughfare in Manhattan runs in one direction, however, making it obvious that the scenes were not filmed on location.

One establishing scene, shown in both the film and one of its trailers, shows the team driving northbound on Broadway past Times Square before their confrontation with Dom. In reality, Broadway is a one-way southbound street, and furthermore, most of its blocks in the Times Square vicinity are closed off to vehicular traffic.

Poltava is in Ukraine, not in Russia as Roman Pearce (Tyrese Gibson) mentions in the movie. Yalta is in former Ukrainian territory of Crimea which was annexed by the Russian Federation on 18 March 2014. As of 2017, the United Nations still maps Crimea as belonging to Ukraine.

Several Manhattan scenes, including the one where Dom stops to "fix" his car, take place in alleyways. In reality, Manhattan has only a handful of alleys, none of them in the vicinity of Midtown where Dom stopped.

During the "Zombie Cars" scene, a 2008 Honda Airwave, and a 2014 Alfa Romeo Giulietta are shown to be hacked. and a 2007 Fiat 500 Lounge is shown although the cars were never sold in the U.S.



Plot holes

The tracking device in Dom's cross has a red blinking light. If the aim is to provide tracking without being detected, a red blinking light is the last thing you'd want. This is a common error in movies with trackers placed on cars and such. It shows the audience the device is active, but it makes no sense whatsoever.

Even if an aircraft could be able to find radar blind spots to fly undetected, it needs to land for refueling. A plane as large as Cipher's (which appears to be a modified Boeing 787) needs large, conventional, commercial airports for such a need.

Even in the realm of these movies, it is quite inconceivable that the Russian military would not be able to change the codes for the atomic rockets in the time the team needs to travel from the United States to Russia.

When Dom says to the team to "head to the shore", they can hear him. But how? The team has communication equipment in their cars to talk to each other, but his car wasn't outfitted by them. He would have had to figure out their frequency and possibly encryption to be able to talk to them.

At the end of Fast and The Furious 6, when they find Letty, Brian and Mia's son Jack is an infant. This is when Dom and Elena broke up. In Furious 7, Jack is school aged. When this movie starts Elena's son is an infant, which means that Elena's son is too young to be Dom's child.
