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: 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 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.
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.
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.
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: When Shelly is possessed, she and Scotty fight and she amputates her own right hand before she goes down. Moments later, she comes back to life and Scotty starts dismembering her with an axe, starting with her left hand. We plainly see the axe come down full-force on her left wrist. However, in two subsequent shots, we see her intact left arm and hand in the foreground, reaching for Scotty as he continues chopping.

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.
