Visible crew/equipment: At Barbara and Phil's house, just as the hooded zombie bites a chunk out of Phil's neck (before Shaun leaps over the car hood) the black mat with two long white marks is visible on the pavement, behind the second zombie (beside the car). It's gone in following shots. (00:46:30)
Visible crew/equipment: In the Jaguar, after Ed explains that he already adjusted the seat and Shaun shouts, "Careful!," when Ed pulls out of the driveway a seated crewmember is reflected on the side of the car. This does not refer to the zombie extras. (00:45:15)
Continuity mistake: When Shaun goes to the newsagents after the dead rise, he gets a drink out of the fridge, which has blood-stained hand prints on. He slips on what we assume is blood as he walks away, yet on the way in and as he leaves the shop you can see behind him that there is no blood or any other liquid on the floor. (00:25:35)
Suggested correction: Have just watched this on the big screen, and there is definitely blood on the floor. It's on the red tile, so it is hard to see; also hard to see on the DVD version.
Visible crew/equipment: When the blue tux zombie walks in through the ever unlocked front door, in the shot facing Ed and Shaun as they get up screaming, two blue tape T-marks are visible on the rug, between the couch and chair. It is visible in a couple of shots, but gone in the rest. (00:31:50)
Visible crew/equipment: When Shaun scales up the side of the building to Liz's apartment the second time, just as he places the cricket mallet on the floor and begins to climb through the window, the steel tubing for the scaffold platform is visible just to his right. (00:49:00)
Revealing mistake: In the beginning of the movie, where it shows the group of nodding zombies and the Shaun of The Dead logo is on the ground, look to your left, the zombie actor stops nodding and looks around him to see if the shot is still being filmed, and he immediately goes back to nodding. Look out for it, it's obvious. (00:03:45)
Continuity mistake: When Ed drives Phil's Jaguar, its rearview mirror disappears and reappears repeatedly. (00:47:15 - 00:53:35)
Continuity mistake: After Ed and Shaun make the plan to save everyone, we see the close-up shot of the TV where the announcer is saying that nobody should try and save their friends and family. If you look at Shaun, you see the handle end of the cricket bat in his right hand, and he is facing the TV screen. In the shots immediately before and after that, Shaun is not only turned away from the TV, but the handle is in his left hand. (00:37:00)
Continuity mistake: When Shaun and Ed repeatedly hit the two zombies in the back garden, no blood appears on the cricket bat or shovel, however it does splatter onto their shirts. (00:33:20)
Continuity mistake: If you look closely as Shaun and the gang impersonate zombies, all the zombies around them are constantly moving between shots. (00:58:40 - 01:00:00)
Continuity mistake: At John's pub, when Liz has a look at Barbara's bloody wound, it is about 2" above her left wrist, but when Shaun lifts his mum's sleeve, it's about 6" above her left wrist. (01:12:30)
Continuity mistake: As David is trying all the switches on the fuse box, he flicks a few off and you can see about a half of dozen of them flicked up. In the following shot only one switch is flicked up. (01:09:25)
Visible crew/equipment: Each time Shaun goes to the store, you can see the reflection of the camera on the freezer's door. (00:08:00)
Continuity mistake: When Shaun climbs up to Liz's apartment, there is a large handbag that hangs on the back of chair beside the window, but it is gone in the next close-up. (00:48:50)
Revealing mistake: When Shaun tackles the blue robe zombie they both slam through the wood fence. The thick black protective vest that Shaun wears is very noticeable under his shirt and is actually visible below his shirt collar. (00:58:10)
Revealing mistake: When Ed hits the zombie in the eye with the record, you can see for a split second that the record misses the zombie completely, then the camera cuts and a different, breakaway (or CGI) record hits the zombie. (00:32:20)
Continuity mistake: When throwing records at the zombies, watch when Ed throws one at the girl. As he throws it, her head is to the left but when the camera shows a close up when the record hits her, her head is to the RIGHT. (00:32:45)
Revealing mistake: When Shaun shoots zombified Pete, the hole in the back of his head doesn't quite move with his actual head.
Continuity mistake: At the beginning of the film, when the camera pans across the road towards Shaun's house, the silver Renault badge on the hood of Pete's car is missing, but when Shaun goes to work that morning (Pete sits in the car), it's there. The badge disappears again later in the film. (00:06:55 - 00:24:25)
