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: 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: In several scenes Ash is completely covered in blood yet seconds later he is almost totally clean.
Continuity mistake: The purple bruise on Ash's face near the end of the movie goes from very large to small, and changes from light to dark throughout shots.
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.
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: In the tree rape scene, Ellen Sandweiss' breast is visible at one point, but then in subsequent shots it is covered again.
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.
Revealing mistake: When Ash is about to gouge out Scotty's eyes, you can see there are already holes in the eyes before he does it.
Revealing mistake: When everyone in the car pulls off the bridge at the beginning they're on the path to the cabin but when Ash and his sister leave the cabin to go back to the bridge suddenly they're speeding down a gravel road.
Continuity mistake: When Scotty stabs Shelley in the back with the sword, she falls and lands on her back, which should have impaled her, but when she's on the ground the sword is nowhere to be seen.
Continuity mistake: When Scotty swerves from the truck in the beginning, Ash is standing up behind him, with his head halfway out of the car, yelling at him to turn the wheel. In the next shot both window are up again. It is just seconds before Scotty honks at the fishermen.
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: 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.
