Continuity mistake: When Scotty honks, and the two guys on the side of the street wave their arms, the window of the car is suddenly open (it was closed before, as can be seen by the reflection) and then again is suddenly closed. (00:02:15)
Continuity mistake: When the blond guy goes into the cabin in the beginning, it goes from day when he's walking in, to completely dark once he's opened the door and gone in. (00:06:00)
Continuity mistake: After the dead possesses Cheryl to draw the book of the dead in her sketch pad, in the last shot of the pad as Cheryl lifts it up, the drawing has additional and extended lines and smudges have appeared/disappeared. (00:08:35)
Continuity mistake: When everyone is eating dinner, the colour of the drink in the blender changes between shots. (00:08:55)
Continuity mistake: At dinner, Cheryl starts pouring a drink. It cuts and she's now suddenly unwrapping foil. (00:09:00)
Continuity mistake: When Ash first finds the book of the dead, he opens it, and in a closeup we see he's on a page with many skulls drawn on it. It cuts and the page he is on is different, with one big skull on it. (00:15:00)
Continuity mistake: Before everyone listens to the tape, you can see that Ash is sitting to the left of Linda, but in the next shot, Ash is by Linda's right. (00:15:40)
Continuity mistake: The design on the box that contains the necklace changes when Ash gives it to his girlfriend. (00:20:45)
Continuity mistake: Cheryl's bracelet switches arms after she starts running from the forest. (00:26:10 - 00:27:20)
Continuity mistake: When Cheryl is running through the woods, she is wearing slippers that stay on up until she reaches the cabin door. However, in following shots, she is shown barefoot, and when Ash opens the door her foot is dirty as if she'd been running barefoot the whole time. (00:28:05 - 00:29:10)
Continuity mistake: The actors' haircuts change a few times. This is noticeable when Scotty pulls back the bath curtain, and his hair is rather long and thick, but when he turns around, his hair is much shorter. Also, Linda's hair is short and wavy, but when she turns evil and she and Ash are fighting outside, her hair is very curly. (00:41:20)
Continuity mistake: When Evil Shelley scratches Scotty's face, you can see her fingernails are very long. But when Shelley and Scotty are fighting by the fireplace, notice that in some shots her fingernails are much shorter, and in other shots they have totally disappeared. (00:41:30)
Continuity mistake: Evil Shelley wears red and white patterned socks as we see when Scotty pulls her out from the fireplace. Later when Scotty is dismembering her with the axe, he hits her ankles, and the socks are now all-red, thick, woolly socks which are longer in length too. (00:42:00 - 00:45:40)
Continuity mistake: Scotty's shirt changes a bunch of times. His normal shirt is blue-and-white plaid, but when he's in the cellar with Ash, close-ups of him dismembering Evil Shelly, and outside after he and Ash have buried the bits of Evil Shelly, it's a plaid that's mostly red with a little yellow and blue. At the end, when Evil Scotty is in claymation, his plaid is mostly yellow with small red and blue stripes. (00:47:25 - 01:19:25)
Continuity mistake: The necklace around Linda's neck disappears from the time when she wakes up as Evil Linda to when Ash chains her down in the shed. (00:51:45 - 01:01:05)
Continuity mistake: When Ash is about to cut Linda with the chainsaw, you get a close up of her necklace, and it is visible, just under her neck. But in the next wide shot, the necklace is further down on top of her dress. (01:01:15)
Continuity mistake: When Ash is beating his dead ex-girlfriend with the plank, you can see the plank start to split in half; in the next shot, it's back to its original form. (01:05:25)
Continuity mistake: When Cheryl is trying to get in the front door, and Ash is pushing against it, Cheryl manages to get her hand in the door. Ash hits it with the end of his gun, which gets blood all over the side of the door and the wall. But in the next shot, the blood has vanished. (01:08:30)
Continuity mistake: When the pipe bursts over him and spills out about a water tower's worth of blood, it covers him, completely soaked him and then when you look at him after the burst, he's cleaner than ever. (01:09:45)
Continuity mistake: When he is in front of the movie projector, the blood starts dripping, it flashes from back and forth, looking at the projector and the projection over Ash. The blood is dripping in spots all over the lens, but when you look on the wall, its dripping from the top. (01:10:15)
