The airplane that Gerry Lane travels in repeatedly switches between an Antonov An-12 and a Lockheed C-130 Hercules.
At the beginning of the film, in the traffic jam, a motorcycle policeman pulls up and tells Gerry to get back in his car; there is nothing behind him but gridlocked traffic; a second later when he tells Gerry to remain in his vehicle, he's suddenly mown down by a PWD dump truck even though as he's pulling up there's two lanes of cars and taxis backed up to the end of the street with no dump truck in sight and no way for it to charge through unobstructed.
The escape from Israel is on board an A310. However the interior of the cabin, as shown in the movie, corresponds to a B777 and not an A310.
The first red-haired zombie Segen shoots can be seen being killed again as Segen and the WHO doctor flee, and then again as Gerry crosses the sky bridge.
The UN pin on Undersecretary Thierry Umutoni's jacket switches from his right-hand jacket lapel to his left and then back to the right.
They use Iridium satellite phones indoors (inside the aircraft carrier, inside the airplane) which is not possible - they need a clear view of the sky.
The explosive decompression caused by a large hole suddenly occurring in plane's fuselage takes but a fraction of a second. After that, inside and outside pressures are equal and nothing is sucked out any more, at least not from a distance of several meters from the hole (although outside the hole there is a 900 km/h air stream which is bound to cause some turbulence inside.)
When arriving in Israel, Gerry Lane uses the call sign 'Reach 394' for his aircraft. While 'Reach' is a real US Air Force call sign, the aircraft in the film is depicted as US Navy and would generally use 'Convoy' as its call sign.
When the grenade detonates in the Airbus, the plane suffers decompression and the pilots' oxygen masks drop, yet the aircraft is flying low (circa 3,000 feet) where the pressure would be equal inside and outside the aircraft so that the oxygen masks would not drop.
The same with the Antonov An-12. That has a better range of 3,500 miles but it still has to refuel at least 3 times to make it from South Korea to Israel.
When Jerry first goes to vault 139 in the lab in Wales, he is carrying a fireaxe as weapon. Later on he is carrying a crowbar. Gerry uses the axe to prop open a swinging door, then receives the crowbar from the doctor helping him locate the vault.
When Connie (Gerry's youngest) complains that the water on the Navy ship tastes funny, one of the sailors says that it's jet fuel and another sailor explains that desal (the desalinization plant) has trouble filtering it out. While it's true that the desalinization plant has no connection to the fuel lines, it's clear that the two sailors are making a joke at the civilians' expense (Karin even tries to reassure her daughter telling her "he's joking").
At the WHO they say they tried to infect the zombies with sicknesses, but then they say all the viruses are inaccessible (in the B wing). However, they only closed off the B wing after trying to infect the zombies with sicknesses.
When the Lane family's Volvo is hit by the ambulance at the beginning of the movie, the car is then shown from the driver's side. It is clear that there is no one in the Volvo, and the person driving the ambulance is wearing stunt gear, complete with helmet.
During the movie's opening action sequence, British-style traffic lights can be seen at the road junctions, behind the US-style traffic lights, giving away the fact that this scene was filmed in Glasgow, Scotland.
When Gerry and family lands on the ship, the camera focuses on the weapon of a military guard. The marking on the weapon is Classic Army. Classic Army is an Airsoft gun brand.
Gerry's axe in the WHO installation is in fact a splitting maul for splitting logs, not a fire axe or emergency axe as its red paint is trying to suggest.
Despite the fact that Gerry (Brad Pitt) is left in a hanging-forward position when his plane crashes, blood on both sides of his face flows straight downward as though he was standing erect after receiving the wounds.
[unrated version only] Looking for their youngest daughter in the Newark apartment building, Gerry and Karin search hallways and an abandoned apartment before finding her yelling "let me in!" to people in a doorway. But a stray "let me in!" can be heard on the soundtrack far too early in the scene.
There is a green Mercedes-Benz C-Class station wagon in the shot while Gerry is picking up the side mirror of his car. That particular model was never sold as a wagon in North America.
When he was in the vault with the diseases, why didn't he hold each one up to the security camera and sign for them to ring the phone when he had a suitable non fatal disease?.
Just before the infected come over the wall in Jerusalem, Gerry says, "If I could get into India, where would I start?" "India's a black hole." The lines originally named Russia, not India, and you can still read Russia on his lips. The editing of the scene fails to completely conceal the second overdub as well.
Various aircraft sound mismatches:
During some of the cargo/transport turboprop aircraft landings and taxiing, the sound of piston aircraft engines can be heard. Turboprop engines would produce more of a whining jet noise, with some other noise generated by the propellers.
Inside the cockpit of the turboprop cargo/transport aircraft, the sound mix representing the aircraft sound includes the sound of at least one helicopter rotor.
(at around 11 mins) As the RV is driving towards the bridge after breaking though the barricade, there is a cameraman visible to the left of the left Humvee.
When Gerry is in the research facility viruses room, while the zombie is outside waiting, a crewmember's face is reflected for a second in one of the windows.
In the exterior shot of the medical facility in Wales at night, the soundtrack has cicadas chirping quietly in the background. There are no cicadas in Wales.
The Pepsi bottles at the WHO offices in Cardiff, UK, have American FDA calorie labels.
As the passenger plane comes in to land at Cardiff Airport the background images show Snowdon and other mountains in the Snowdonia region. It would be highly unlikely that a route from Jerusalem to South Wales would take them to North Wales.
When people are shown entering Jerusalem through a checkpoint, a medical tent is shown with a Red Cross instead of The Red Star of David, the emblem that Israel uses.
In Israel, car license plates are yellow but many parked cars have white plates.
Although there are many helicopters patrolling the area around Jerusalem, the pile of zombies that overrun the wall are, for some reason, not noticed by any of them until it was too late to curb the threat.
Also, once the helicopter starts shooting at the zombies, it moves past them like a fixed-wing aircraft. The helicopter could hover then, working from top to bottom, shoot down all the zombies climbing the wall.

The 'U.N. Fleet' is shown stationed about 100 miles north of Bermuda. While it is likely the rest of the world is infected, most, if not all, of the world's islands would be safe havens as the 'zombies' would not be able to travel to them, being unable to ride on or operate the small boats and planes that service the islands. The people in the fleet could therefore easily visit or even live on them, but they don't appear to realise this and choose to remain at sea for some unexplained reason.
When Gerry reaches vault 139 in the W.H.O. facility, the female W.H.O. doctor calls him to give him the code to enter the vault but fails to tell him exactly what vials to get, causing him to have to take them all.
Gerry's satellite phone ringing alerts zombies at Camp Humphrey but not the four engines of a landing C-130 Hercules.
If sick people are essentially invisible to the zombies and don't get infected, the army should have known about it much earlier in the movie, as there are tens of thousands of people in the world who are sick at any given time.
However, there was no reason for anyone in the army to make that connection. Gerry only worked it out following his conversation with Fassbach and reflecting on what he'd witnessed.
