Corrected entry: In the scene near the end when the zombies begin breaking in and Shaun is describing how much ammo he has, he calls his ammo bullets and Ed corrects him and says they are called shells. Shaun had it right the first time. Ammo for a rifle are cartridges, and ammo for a shotgun is called shells.
Corrected entry: 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. (01:21:45)
Corrected entry: Mary, the woman in the garden, can be seen working at a supermarket checkout at the start of the film.
Corrected entry: Near the start of the film, when Ed is telling Shaun who called, he says 'First your mom rang about going round tomorrow night, then Liz rang about the two of you eating out tonight.' But Liz called just as Shaun was leaving to go work therefore Shaun's mom couldn't have called before Liz.
Corrected entry: Many of the people that appear in the opening titles reappear as zombies later in the movie. The woman behind the till plays Mary, the 'girl in the garden', all the members of the bus queue appear somewhere, the nodding zombies reappear and take a bite out of Phillip's shoulder and the boy with the football is always outside Shaun's house.
Corrected entry: When its Shaun's second walk to the store, Shaun doesn't have enough money for the beer and ice cream cone he's going to buy so he says he's going to leave about 15p. Later in the movie, the owner of the shop appears as a zombie with his hand outstretched gesturing "You owe me money".
Corrected entry: In the scene when Shaun, Liz and Ed are hiding behind the bar trying not to get tagged by the zombies, Shaun's shirt is white with five or six red spots on the front. Five seconds after they managed to get down into the cellar, Shaun's shirt is dark blue and black all over with loads of red spots.
Corrected entry: While heading towards the Winchester in the Jaguar, the driver intentionally goes into a 720 degree spin. He'd be lucky to get a 180 degree spin on dry pavement. (00:51:20)
