Continuity mistake: When Columbus and Tallahassee first meet, they are sitting in the car and Tallahassee picks up his bottle of 'alcohol'. The label on the bottle changes sides depending on camera angle. From Columbus' side the label is facing toward the front of the car (with Tallahassee's fingers over it), but from Tallahassee's side the label is facing towards the driver's window. It then changes back and forth depending on camera angle. (00:09:20)
Continuity mistake: When Tallahassee and Columbus discover the abandoned Hummer, the camera pans in on the two hands attached to the steering wheel. From this angle, you can see Columbus looking in through the passenger door window while the door is shut. Immediately the camera pans to another angle, showing Tallahassee pulling one of the hands off the steering wheel and in this shot, Columbus's door is open. There wasn't enough time between shots for him to have opened the car door and there was no sound indicating that he had done so. (00:09:30)
Continuity mistake: In the scene after Wichita and Little Rock stole Tallahassee's SUV, we see a huge shot of the camera panning downward as Columbus is talking to Tallahassee. We get to see a clear shot of the sky, which is very cloudy and no visible sun. As the camera moves with the two as they continue off screen, the next shot is from directly in front of them walking forward. However this time the sun is glaring brightly behind them leaving shadows from the buildings and lighting the road up with the bright sun. But in the shot before it was a very cloudy day. (00:27:20 - 00:28:20)
Visible crew/equipment: Just before Tallahassee tears up the minivan, a crew member's legs are visible below the posters in the window of the Citizens United storefront. (00:36:00)
Suggested correction: It's the legs of Tallahassee himself in the reflection, and they copy all his movements exactly.
Continuity mistake: When Tallahassee is taking cover in the booth, he is closing the security screens, but he does not lock them, He does not lock them later either, because you can see that the gate is slightly open, but later you can see a big lock holding the screen closed. (01:15:50 - 01:16:40)
Plot hole: With people around the world turned into zombies, there is no way to maintain power plants, thus no lights should be lit, not to mention the functionality of an amusement park.
Suggested correction: The sequel film gives this a (very flimsy) justification, saying that everything runs on power from dams. Stupid, but at least trying to explain things.
Continuity mistake: When Columbus brushes Wichita's hair behind her ear and kisses her, he leaves his hand behind her ear. Her hair changes position between shots; in some it is all behind her ear, in some it is over Columbus' hand, and in others it is half and half.
Continuity mistake: In the Pacific Playland scene, Wichita and Little Rock are seen riding a Swinging Ship when all of a sudden, zombies begin to pile over the park's fence. In the next scene, the two girls are shown running down a stretch of walkway shooting at the zombies that are chasing them. When the camera is focused on the zombies pursuing the girls, in the background (top left corner) you can see the Ship ride sitting still. After the camera gets a shot of the girls, it goes back to the shot of the zombies and the Ship is now moving in full swing. The next time the zombies are shown, the Ship is sitting still again. There was no time between shots for the ride to have started and stopped so quickly.
Continuity mistake: When Tallahassee first appears, driving the Escalade, he smashes into a car, which badly dents his "snow plow" (very easy to see). In the next and subsequent shots, it is as nice and straight as before.
Other mistake: When Columbus is face-to-face with the clown zombie, he looks up at Wichita, who is on the ride, stuck at the top of the tower. Columbus looks almost straight up at her, but when Wichita looks to Columbus for help, she should look almost straight down, but instead she looks straight ahead. There is no other reason why she would have looked straight ahead because a) Columbus was directly below her, b) Little Rock and Tallahassee were to her right, and c) she almost perpetually had her eyes on the zombie climbing the tower towards her.
Continuity mistake: When Tallahassee is locked in the prize booth, he is holding a SIG and a Colt 1911. When he is done and spins his guns, he is holding two Colts.
Factual error: During the stop in the small town while still in Texas, and Tallahassee breaks all the windows in the minivan, a Bank of Coweta sign is visible over one of the buildings. The Bank of Coweta is a local bank in Georgia, and has no branches outside of the state.
Continuity mistake: After Tallahassee and Columbus find the yellow vehicle, Tallahassee paints the number "3" on the sides. The style that the "3" is painted in changes throughout the movie.
Continuity mistake: Woody Harrelson locks himself in the booth at Pacific Playland and locks/closes the security screens on three sides. After he is surrounded by zombies, one of the side cages has been pushed opened a bit, leaving quite a gap. The scene pans around to various angles as Woody fires away, and in a subsequent shot, the screen is shut again. With both his hands full, he couldn't have shut it.
Visible crew/equipment: As Tallahassee is driving them to Bill Murray's house in the Hummer, you can see the camera crew riding alongside in the reflection on the truck.
Continuity mistake: When Wichita and Little Rock are about to enter Pacific play land. you are able to see Wichita wearing the hair loose. just after crossing the main door, Wichita is wearing her hair tied.
Suggested correction: Her hair is always tied.
Character mistake: When Tallahassee firsts meets Bill Murray, He says "six people left in the world and you're one of them." At that point they only know of 5 - the 4 main characters and Bill Murray.
Suggested correction: His character thinks there was another woman that Columbus hooked up with in the back of a FedEx truck.
Other mistake: Most of the time when driving, the windows are down (possibly so no camera reflections are seen) but their hair mostly doesn't move and there is no wind noise in the truck like there would normally be.
Factual error: When Tallahassee and Columbus open the crashed Hostess truck, a huge pile of individual Sno-Balls packages pour out. A real delivery truck would have the product packaged in boxes on shelves in the back of the truck. Even if a Hostess employee was frantically filling the truck before he fled for some reason, Hostess products come from the factory and distributor in boxes.
Continuity mistake: When the younger sister (Little Rock) is picking up the fake ring in front of the gas station, behind her is a PT Cruiser getting gas. Immediately when the gas station attendant comes out to speak to her, the car has vanished. There was no possible way the car was driven away in the split second scene switch.
