Continuity mistake: There are 5 different colours of blood used throughout the movie. Ash always gets soaked by blood (either chopping Linda's head up, or hacking Professor Noble to pieces), but always ends up dry in the next shot. [The reason why there are 5 types of blood: The creators wanted to get an R rating instead of NC-17, so they used different colors for slime instead of blood. It failed, they got an NC-17 rating and then released it independently with a non-rated rating.] (00:22:00 - 00:45:30)
Factual error: A line of blood flies onto the door of the work shed while Ash is using the chainsaw on Linda's head. However, the shadows of Ash and the head show that they are perpendicular to the door. All of the blood would be moved by the chainsaw in the direction of the cut, either toward Ash or the wall behind the head, so there is no way that much blood could land on the door. (00:22:00)
Continuity mistake: When Ash leaves the workshed after cutting up Linda he only locks the door to the workshed with the chain, later on he goes into it and unlocks the chain and the piece of wood. (00:22:20 - 01:06:20)
Continuity mistake: After Ask looks in the mirror, as his hand starts to turn evil, green slime has appeared on Ash's shirt. (00:22:40)
Continuity mistake: When Ash lays on the floor, after his evil hand has attacked him, the wrappers, boxes, smashed china etc. around him moves around between shots. (00:26:35)
Audio problem: It's quite obvious that all of the grunts and sounds of terror that Ash makes while his hand is attacking him in the kitchen are dubbed. (00:28:45)
Audio problem: After Linda's head is possessed and bites Ash's hand, as he's getting up and going to the work shed, his mouth doesn't move as he says the word "work-shed", and it is obvious that it is dubbed in. (00:28:55)
Continuity mistake: Ash chops his hand off at the wrist, yet later it is seen to have a fair amount of forearm attached to it. (00:29:00)
Continuity mistake: The mousetrap is visible outside of the hole in the wall, before the hand gets it's thumb stuck in it and leaves the trap outside the hole. (00:31:25)
Continuity mistake: The hand gets it's thumb caught in a mousetrap, yet in the next shot it's index finger is the one caught in the trap. (00:31:40)
Revealing mistake: As Ash is duct-taping his sleeve shut after he cuts off his hand, you can see the impression of his largest knuckles and first two fingers under the cloth. (00:31:45)
Factual error: As Ash is hunting his rebellious hand, he blows a hole about the size of a fist in the wall, then removes two spent shells from the shotgun. At that range, a double-barreled shotgun blast would have dealt much more damage. At several later points, he deals the exact same damage to a wall with only one barrel. (00:32:45)
Continuity mistake: No matter how many times Ash has blood poured on him or landed in mud, he will always have a clean face with his freshly made scars, scenes after he has been blood bathed or mud wrestled. (00:34:05)
Continuity mistake: When Annie grabs Ash while he is lying on the floor you see lots of blood getting all over Annie's right shirt sleeve. Later on her shirt is totally clean. (00:36:20 - 00:37:30)
Revealing mistake: After Ash is punched unconcious by Jake, as Annie shakes him, screaming at him, he grabs her arm, although he's out cold. (00:36:25)
Continuity mistake: When Ash is thrown into the cellar he breaks a few of the steps. Later when he goes in to retrieve the pages of the Necronomicon every step is intact. (00:38:30 - 01:08:10)
Revealing mistake: When the eye is flying toward Bobby Jo, you can see the rig holding the eye as it flies and the wire when it enters her mouth. (00:41:45)
Visible crew/equipment: When Evil Ed is floating in the air screaming "dead by dawn" you can see the black wire attached to his back. (00:42:55)
Continuity mistake: After Ash hacks Evil Ed up, a lot of the green blood which sprays all over the walls disappears. (00:43:40)
Continuity mistake: When Ash hacks Evil Ed, the clock reads 11:10. Later when the clock is shown stopping, it is 10:40. (00:43:40 - 00:45:00)
Chosen answer: Evil Dead II starts out with a recap of The Evil Dead where Ash cuts off the head of his girlfriend Linda with a shovel and then is attacked by the entity, which is how the first film ended. While Linda is played by a different actress, it's still meant to be the same events as The Evil Dead. The cabin windows are still barricaded from the end of the first Evil Dead, and Ash's pant leg is still torn from Deadite Scott attacking Ash. Additionally, the end credits say: "Evil Dead II", the sequel to the ultimate experience in grueling horror, was filmed in Wadesboro, North Carolina and Detroit, U.S.A.
