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 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: 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.
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.
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: When Little Rock takes Columbus and Tallahassee hostage inside the Hummer, she holds up a gun to Tallahassee's neck. In this shot, her hair is in front of her ear. The next time she is shown, where she shoots the gun through the sun roof, her hair is shown tucked behind her ear two different ways. Seconds later, when she takes Tallahassee's gun away from him, her hair is in front of her ear again. This pattern continues for the rest of the scene. Since both of her hands were on the gun, she shouldn't have been able to adjust her hair.
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)
Continuity mistake: When the girls are on the blast off ride and they shoot the control box, you can see that they are 1/4 of the way down but in the next shot they are all the way at the top of the ride.
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.
