Continuity: In the cellar, Shaun lights Ed's last cigarette and it appears to have barely caught on one side. The next shot, the cigarette's burned down evenly about half a centimetre, which means it's a different one from the one he lit before. (Tried this with a real cigarette before submitting. They just don't burn like that.). (Time)

Continuity: Mary (the checkout clerk who later appears in Shaun's garden as a zombie) works for a fictional supermarket chain, "Landis." But in the opening montage, all the till screens display "Welcome to ASDA" (Asda is a real chain of supermarkets in the UK). (Time)

Continuity: When David is pointing the rifle at Barbara and Shaun, you see the barrel of the rifle and David's hand holding it. When the camera moves so you can see David's face, his hands are higher up on the barrel. It's the same when the camera switches between these two shots again while Shaun and David are arguing. (Time)

Continuity: In the scene where Ed smashes the ashtray on the zombie's head, his right hand goes to pick up the ashtray. In the next shot, his right hand is empty and in the close shot of the zombie we see the ashtray in Ed's hand again. (Time)

Revealing: You can blatantly tell the pub owner zombie has padding on under his shirt for the pool cue attacks. (Time)

Continuity: Shaun's "To Do" list, which he writes on the whiteboard, changes. He doesn't write an exclamation mark, and he swipes the marker pen through the word "OUT." However when we see it the following morning when he awakes, there is a exclamation mark after the word "OUT", and the lines he drew through the word "OUT" have moved and are now underneath the word.

Continuity: In the beginning when Shaun is at work and is talking with Liz on the phone, when they are done he puts the phone down. Two cuts later we see him putting it down again. (Time) Submitted by Mortug

Other: Ed strikes several zombies while driving the Jaguar. However, the car doesn't even get a single scratch. (Time)

Continuity: The red ink on Shaun's pocket at work changes from a solid blob to one with a few spots above it back to solid. (Time)

Factual error: When Shaun, Ed, and Liz are hiding behind the bar in the pub that they've lit on fire, Ed tells Shaun he's left the shells on the counter. Shortly thereafter, the fire ignites the box of shells and bullets start to hit the zombies around them. However, casings for bullets are very weak and without a steel barrel around the shell the casing would rupture before enough pressure formed behind the bullet to propel it at any dangerous velocity. It's only when the casing has reinforcement around it that a bullet becomes dangerous. (Time)
