Incorrectly regarded as goofs

At the amusement park, as soon as one of the breakers is turned on, the roller coaster lights up and a car goes flying down the track. It would have had to have been pulled up the hill first before being able to go down the track. If the amusement park was shut down in a hurry the power may have gone off while the car may still be at the top.

Factual errors

The first ride that Wichita and Little Rock ride at Pacific Playland requires an attendant to be present to hold down an "operator present" button for the ride to function. If no one is at the park to operate the ride, then the girls would not be able to ride it.

Plot holes

When Tallahassee manages to grab his gun from Little Rock, Wichita threatens him with a pistol. Where she got it, and why she never uses it before or after this scene is unexplained.

Plot holes

The film takes place 2 months after the first zombie attacks, but still we see a functioning power grid and electricity everywhere. This is highly unlikely without human supervision.

Errors in geography

When Columbus and Tallahassee first get the hummer, the road that they are seen driving on in Texas, is the same road the entire group is seen driving on just as the pass the sign that says "Welcome to California."

Crew or equipment visible

When Tallahassee finds the yellow hummer, he opens the drivers door and the camera is visible in the mirror.

Crew or equipment visible

When Tallahasee and Columbus are in the supermarket, Tallahasee kills a zombie with a banjo. In the next shot of him he is holding what appears to be a metal pipe and the banjo has gone. However, the "metal pipe" is an aluminum baseball bat. Tallahassee is seen with the bat prior to playing the banjo. After killing the first zombie with the banjo, he switches to the bat. Then switches to the pruning sheers before killing the third zombie. It's clear that he uses each weapon only once, then changes each time.

When Columbus goes to save Wichita and Little Rock, who are stuck on a ride, he is faced with a clown. He checks his pockets and pulls out two shells in a zip-lock bag.

When Little Rock and Wichita go to the amusement park, they leave the mansion in the morning, and arrive when it is dark. However, when Tallahassee and Columbus go after them, they leave in darkness, and arrive in darkness. The girls are still on the ride when they arrive. Tallahassee and Columbus may have driven a lot faster than the girls, and its not implausible that the 2 girls managed to stay alive on the ride for as long as they did, and nothing suggests that the guys arrive much later than the girls

Audio/visual unsynchronised

Saluting the late Bill Murray with gunfire, Tallahassee, Columbus and Wichita fire their weapons, but Little Rock does not pull the trigger. It can be clearly seen that she does not pull the trigger yet there is a sound to signify that she has, and she also proceeds to reload her gun three times without pulling the trigger once.

Continuity

In the very next shot, with no apparent time lost between cuts, the male zombie is now much further away.

Plot holes

When Columbus and Tallahassee are at the Hostess truck and Tallahassee is flipping out because the truck contains Snowballs instead of Twinkies, the two shots from the inside of the truck show that their are indeed Twinkies behind the other door.

At the beginning of the film, Columbus states that he is making his way from his dorm room in Austin to Columbus. In a later flashback, it is obvious he lives in an apartment, not a dormitory. However, if he is attending school at the University of Texas this is a possible type of housing since the university is not able to support the freshman class in traditional dormitories. Columbus may be living in a housing co-op which could resemble an apartment more than a dormitory

Incorrectly regarded as goofs

Tallahassee says there are six people alive in the world when he meets Bill Murray. Outside of flashbacks, there are only five live people in the movie - Columbus, Tallahassee, Wichita, Little Rock and Murray. However, Cynthia Knickerbocker earned Zombie Kill of the Week about halfway through the movie, which brings the count to six living people even though there are only five alive in the party. In addition, Tallahassee may have simply been paraphrasing; unless he checked every square inch of the planet, there's no way he could know exactly how many people were still alive in the world.

'Remember Mad Cow Disease?' explains the protagonist. 'Well, Mad Cow became Mad Person, became Mad Zombie.

Continuity

When Tallahassee barricades himself in the game booth at Pacific Playland, he prepares for his gunfight by placing four magazines on the counter in the following order (left to right): One single-stack mag, one double-stack mag, one single-stack, one double-stack.

Additionally, both guns are empty and he dropped the magazines from both guns, but when he slams the guns down onto the magazines, he only actually reloads one gun. Three mags are left on the counter (one double, two singles).

Continuity

When Tallahassee and Columbus are outside the grocery store, Tallahassee is taking out various weapons for destruction, one of them is a baseball bat. As he is talking about the expiration date of the Twinkie you can see there is no weight on the bat (used for practicing your swing as it makes your swing slower). As they enter the store all of a sudden a red weight has been added.

Incorrectly regarded as goofs

When the party gets to the theme park, they turn the power on in order to ride the rides; however, there are two possible problems with this. On one hand, since nobody is running the power plant, it is unlikely that it would be generating power and on the other hand, it is unlikely that anybody would have had or taken the time to turn off the power in the first place. If it was soon after the zombie apocalypse as implied there may still be electricity for a short while.

Audio/visual unsynchronised
