Revealing mistake: When Ash shoots Cheryl through the door in the head, you can clearly see the hose (not an artery) that's squirting out the blood.
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.
Visible crew/equipment: When the people are driving over the bridge at the start, it goes to a shot of the front of the car. To the right of the car you can see a crew member holding a still camera.
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.
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.
Audio problem: When their car is making a sharp turn at the beginning of the film, you can hear the tires screeching. This could only happen if they were on concrete, not on a dirt road.
Continuity mistake: The clock in living room of the cabin shows 5:52p (approx.) at the time it stops toward the beginning of the film. At the point that Scott is "re-animated" and attacks Ash in the climactic scene, it shows 3:10 until it restarts at the very end. This change is NOT accounted for by the clock running backwards as Ash is coming up from the cellar with the shotgun shells as the next shot of the clock shows it to again be at 5:52.
Continuity mistake: After the recently possessed Cheryl stabs Linda in the ankle with a pencil, she draws back her arm to attack again and her wrist is grabbed by Ash to prevent her from doing so. The shot of the stabbing shows the pencil to be covered with blood,but in the close-up of her being stopped by Ash, no blood on the pencil. The pencil is bloody again in the shot of Cheryl coming after Ash after having tossed him and Linda aside.
Continuity mistake: When Scotty stabs Shelley in the back with the ancient sword, the wide shot shows him with his arm around her holding the sword. In the next shot, his arm is no longer around Shelley.
Continuity mistake: When the girls are guessing the cards, the card before Cheryl begins talking is an 8 of diamonds, but in the next shot the card is a queen of spades, with no time to change.
Continuity mistake: As Cheryl is wacking Ash on his back with the fireplace poker, she is holding it with the pointed end away from her. When Ash burns the "Book Of the Dead" in the fire, Cheryl is holding the poker to hit him again but loses her grip. The rounded, knobby end would have struck the floor next to Ash's head, not the pointed end as shown in the shot, as it would have been pointed towards the ceiling.
Revealing mistake: When Ash is leaving the cabin at the end, you can see the holes made by Evil Cheryl were obviously cut by saws: the left one is almost a perfect pentagon and they're cut cleanly all the way through.
Continuity mistake: When Ash is burying his girlfriend, he cuts off her head, and he gets blood all over his face. He runs back to the house, and suddenly the blood is gone.
Revealing mistake: When the blood filled light bulb explodes it is obviously not a real light bulb. When the mantle explodes you can see a small light bulb inside it.
Continuity mistake: At one point in the movie, evil Cheryl thrusts her arms through the door, grabbing Ash, and creating two holes in the door. The size of these holes changes- compare them at the part where Ash is putting a bureau in front of the door (to keep Cheryl from getting in) to the part at the end where Ash is walking out of the cabin.
Revealing mistake: When the girl chews off her own hand, when she pulls her face up, you can see the line where the makeup/mask ends and her normal skin begins.
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.
Revealing mistake: When Cheryl is being attacked by the trees, the branches are wrapping around her. You can see that, in the close-up shot of her right arm, the branch going around her arm is actually twisted yellow rope twine, NOT a branch!
Revealing mistake: In all the nighttime scenes in the woods where the moon is shown, you can see the clear edges of the matte they used to show the moon. The color of the entire woods set is almost black except for the navy blue "rectangle" around the moon.
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.
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.
Deliberate mistake: When they are listening to the tape, Cheryl yells out and shuts it off. Scott says he wants to hear the rest of it, but then deliberately fast-forwards it a bit before starting it playing. If he wanted to hear the rest of it, why does he skip part of it? This allowed Cheryl to shut it off as soon as she finished her line/action, but then Scott could fast-forward it past a mark on the visible reel-to-reel tape so it would start immediately on the chanting rather than in the middle of the lecture where Cheryl stopped it.
Continuity mistake: At the end of the movie, when evil-Cheryl is disintegrating, the hole that was shot in her face moves from one cheek to the other as the shots flash back and forth between her and Ash.
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.
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.
Continuity mistake: Just after Ash has defeated the demons by throwing the book into the fire, he realises that it is dawn, if you look outside the window it is really bright outside yet when he actually steps out of the cabin, the sky is orange as the sun is just rising.
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.
Visible crew/equipment: When Scotty enters the cabin for the very first time, he walks around for a moment. As he passes a window look into the reflection. You can barely see a man dressed all in black holding the camera. His brown equipment belt is very visible.
