Continuity mistake: Just before the garbage truck mows down the policeman and continues through traffic, we see behind the cop a street full of stopped cars, and a building less than 100 yards away (the street starts at a T-intersection). There is no truck, and no way for it to have gotten onto the street at the speed it's going. (00:07:05)
Continuity mistake: After the family reaches the apartment and everyone is listening to the radio, the light for the fish tank is on while the power is out.
Continuity mistake: Just before the motorcycle cop smacks their car's mirror off, Gerry says to Karin "You're not British anymore baby." As he does, she raises her coffee cup to her face in the frontal shot. It then cuts to an angle to show him, and suddenly her arm is down, where she raises her coffee cup to her face again. (00:06:05)
Continuity mistake: The plane that Brad Pitt gets on board in Israel is a Airbus A310 from the exterior shot, but the interior scenes take place in some kind of Boeing widebody aircraft, as noted by the Boeing signature interior, and more significantly the design of the overhead compartments. (01:07:55 - 01:16:50)
Continuity mistake: During the outbreak on the plane, the same guy is seen running from his seat twice after each of the baggage walls is broken down. (01:18:00)
Continuity mistake: While playing games in the car, at one point a white van can be seen out Karin's window. The shot cuts to the daughters in the back as Gerry asks if it "is kept in a pen all its life and harvested for meat?" then back to the wife, and suddenly the van has vanished and you can see a couple people out the widow. The shot change was not long enough for either vehicle to move enough. (00:05:30)
Continuity mistake: After the motorcycle cop knocks off his car's mirror, Gerry gets out to pick it up but doesn't shut his door fully, leaving it about half open. When the guy in the red car gets out and asks if he is all right, the door is suddenly not open as wide. Then it is back to how wide it was in the next shot. (00:06:30)
Continuity mistake: When Gerry and his family are escaping the first wave of the zombies they encounter, they steal an RV and make a run for it. While trying to shake a zombie off the vehicle, Gerry smacks into a taxi, bending the bumper and busting out the headlights on the RV's left side. A little bit later in the film as they are traveling down a highway, they pull to the side of the road to try and find Rachel's spare inhaler, and the front of the RV is shown. The bumper is still bent, but the headlights are now fixed again. (00:10:25)
Continuity mistake: There are two different transport planes shown when flying to Korea and again to Israel. The first shot taking off from the aircraft carrier is an Antonov AN-12, but then other shots show a C130 Hercules. Some of the inside cockpit and cargo area shots are sometimes a C130 cockpit (can tell by the types of windows and cargo seats) but others times a different plane. (00:32:35 - 00:49:20)
Continuity mistake: As Gerry, Segen, and the head of W.H.O. Are walking through the cafeteria of B-Wing, the head of W.H.O. accidentally kicks a can of Mountain Dew which slides across the floor. Just after this, the other W.H.O. Scientists are shown looking at the three in 3 different security monitors. The movements of the three in each monitor is different and does not match up if you look closely. (01:29:30)
Continuity mistake: Gerry is standing by his stove where he is cooking pancakes, looking to his right at the TV. Above the TV is a cabinet with a purple sticker on it. As his daughters and wife get up to leave the room, he is suddenly standing next to this cabinet. Then, only a split second later, as he says "Hey! Plates in the sink!" he is suddenly back in front of his stove, which is a few feet away. He moves to these spots instantaneously. (00:04:55)
Continuity mistake: In the scene where the plane decompresses, the pilots are shown putting on air masks. Seconds later just before the plane crashes, the pilot is again shown, this time without an air mask.
Continuity mistake: The girls are kicked off the USS Argus when the military thinks Gerry is dead. Thierry sends them off on a helicopter. As they board the helicopter, we see a bridge structure behind Thierry, who is looking down the length of the ship at them - and also behind them is 'the same' bridge structure. It has been shown, in several shots through the film, that the Argus has just one such structure. (01:25:20)
Continuity mistake: The first guy that Gerry watches turn into a zombie, and figures out the transformation takes about 12 seconds, he sees go to his car first. The guy opens his door and his right arm is down towards the center of the door. The angle changes and suddenly his right arm is up towards the top of the door. (00:09:05)
Continuity mistake: In the car, before the first zombie attack seen in the film, the family's two daughters are in the back seat as they are playing a family game. The youngest one, Connie, leans over to whisper in Rachel's ear, and it is a profile shot of her face and arm, her neck and some of her chest visible. It cuts to a different angle as she is sitting up, and suddenly she has what appears to be a large stuffed bunny or mouse in her arms, with its ears covering a lot of her face that was not visible in the previous shot.
