Continuity mistake: During the chase scene on the bridge involving the tank, two cars (silver Toyota Corolla hatchback, licence NE34 12 and a black VW Bora, licence NU67 67) appear during many shots, often travelling in different directions on the bridge and either ahead or behind the chase.
Continuity mistake: During the scene where the cable is shot into the sides of the cliffs to stop the convoy, there are no civilians in the area. As soon as the convoy hits the cable and stops, you can see two normal cars just feet away from it. Not only were the cars never there before, but they would have also gotten stopped by the cable.
Continuity mistake: When Roman is fighting the guy on the bonnet of Shaw's Land Rover, Tej signals him to get back on his Mercedes jeep. When Roman does this, the jeeps are pressed up against one another. Then Tej rams Shaw's Land Rover into the jetwash of the plane. Right before he does this, suddenly a massive gap has appeared between the cars.
Continuity mistake: Tej tells Hobbs he's got this, and the scene changes to establishing shots around London. The first shot shows a shot of London, featuring many landmarks and Big Ben in the background. The time in the first shot is 2:10. The shot changes with the camera closer to Big Ben and the time is suddenly 3:00.
Continuity mistake: In scenes showing how Letty survived the explosion it shows her crawling out of the car then getting blown down the hill, but in Fast and Furious she is still in the car when Phoenix shoots it, causing the explosion, so she couldn't have been blown down the hill.
Continuity mistake: At the shoot out, Gisele is talking with the wounded man who made the gadgets. He has a small amount of blood spilling out of his mouth, down the side of his cheek. A couple of shots later, the blood is now a long streak down his cheek. Then it is suddenly just a tiny smear of blood around the edge of his mouth.
Continuity mistake: Roman removes a 100 Grand bar from the shot-down vending machine. In the close-up shot, there are several other 100 Grand bars visible. One of them is held by springs on both sides, with the left side slightly raised. In the next shot, that specific bar has vanished from the pile.
Continuity mistake: When Brian and Mia are in the red Alfa on the runway, Vegh comes after them in one of the flip cars. Brian turns the car around to trick her into crashing into the barriers but after the turn the red Alfa is still going towards the plane so to speak, and Vegh is going in the opposite direction. When she crashes, the red Alfa is suddenly going the other way, away from the plane.
Continuity mistake: Shaw parks his Mercedes on the left side of the plane facing forward. Dom then comes in and parks his Charger on the right of the Mercedes, also facing forwards. But when Shaw wants to drive out of there, the Mercedes is now facing backwards, and it and the Charger have switched sides. Now the cars did move around a little when the plane was leaning, but this does not explain how the Charger would have moved "uphill".
