Other mistake: When Tommy Lee Jones calls up the asset as he lands in Las Vegas you can see him holding the mobile phone upside down with the camera near his mouth and microphone up.
Other mistake: Colin Salmon in Box Command introduces himself to Banning as Chief Inspector. However, the rank on his shirt is of a Commander rank.
Other mistake: In the Watertown police shootout scene, a resident tosses a sledgehammer to the police to help them in the fight. Right when the resident throws the sledgehammer from their front door, many frames are entirely missing from the movie for some reason, which results in an awkward skip. This is seen in all cuts of the film (Blu-Ray, Digital, etc).
Other mistake: Merrit claims he has never ridden a motorcycle and talks about how unsafe it is, but is seen riding one in the first film.
Other mistake: At the very start, Vee opens Chrome but the window that appears is Safari. (00:00:50)
Other mistake: When the truck driver gets his truck cleaned at the start, he starts to drive forwards to a worker at the quarantine checkpoint. The wide shot shows the truck driving towards the worker, but when the shot ends, the truck has not quite gone passed him. We are then shown a shot of the truck driver stopping the truck and rolling down the window. In the shot, the driver is shown looking directly to his left to be face to face with the quarantine worker, right as the shot begins. There's no way the driver could have been immediately looking at the worker at the start of the shot as the truck had yet to go past the driver at the end of the previous shot. (00:01:20)
Other mistake: Misty's car at the beginning of the movie crashes into the house presumably breaking through the perimeter wall, certainly does smash through interior walls and furniture, but in the living room it still has every single light, including the side ones, completely whole and undamaged.
Other mistake: During the scene when Jack's wife is ordering at McDonald's, the little girls are mouthing the lines as the others are saying them.
