A Nightmare on Elm Street 4 (1988) - 27 mistakes

Visible crew/equipment: In the scene where the souls are coming out of Freddy's chest, in the first close-up on the bottom left of the screen you can see a man's hand holding a black stick to manuoever the little arms. It's real fast but noticable on standard play.

Revealing: After her brother's death, there is a scene in which Alice starts practicing with her brother's nun-chuks. They never show the real actress doing the tricks; instead, they cut to an angle from behind her and show a double who has darker, shorter hair than the real actress and is a bit bigger.

Continuity: At Rick's funeral, Debbie gives Alice her spike bracelet. The spikes are flat and there aren't that many of them, but at the end when Alice is getting decked out to fight Freddy she pulls the bracelet out of her drawer, and the spikes are very menacing looking and there are more of them.

Continuity: When Alice is holding onto the edge of the wall in the cinema because she is being blown to the screen, between shots Alice's shoe flies off of her foot twice.

Continuity: In her dream, Kristen is bit by Kincaid's dog on her right arm. When she wakes up, the wound is on her left arm.

Continuity: When Sheila's pen bleeds, she puts the pen down, then smears the blood around her physics test. Between shots, the way the blood has smeared changes.

Continuity: When Sheila's pen starts to bleed, she puts it down on her desk, with the lid off. In the next shot there's a lid on it, and the pen has also changed it position. Her inhaler has also changed position.

Revealing: When Alice is being blown towards the cinema screen, she grabs hold of one of the cinema chairs. You can clearly see she is actually holding a handle which is on top of the chair. This is blatantly visible when she lets go of it and flies off.

Continuity: When Freddy is reaching out to take Sheila's glasses off, you can see that the palm and index finger of his hand aren't scarred at all from what was supposed to be an all-consuming fire.

Continuity: When Kristen meets the little girl drawing the chalk house, between the two shots before it starts raining, the chalk drawing changes.

Continuity: In the scene where Debbie's arms come off you see two right arms fall to the ground instead of a left and a right.

Revealing: When Shelia is dying, Alice is trying to help her, but she is 'thrown' to the floor. Then there is another shot of Shelia, and you clearly see a pulse in her neck, although she's meant to be dead.

Continuity: When Freddy push Kristen into the quicksand you see only her hand sticking up. Then in the next shot suddenly you see her hair.

Continuity: When Kincaid's dog runs under the bed, it kicks a carpet away from the bed. Beside the bedpost there is a white sock. When it cuts, the sock has moved onto the carpet.

Continuity: After Kristen first falls into the quicksand, the shot changes, and a palm tree appears which wasn't there before.

Continuity: When Dan is talking to Alice there is a piece of paper in front of him on the table. In the next shot it's gone.

Continuity: When Kincaid falls backward out of the chair we see his dog sticking its head out under the bed. When it cuts to Kincaid falling through the wall, the dog isn't under the bed.

Continuity: When the nib of Shelia's pen starts bleeding on her test, the pool of blood on her paper moves between shots.

Continuity: When Freddy is pushing down on the weight Debbie is holding, in one shot Debbie is holding the middle of the weight with both hands, then when the shot changes she is holding the weight with one hand either side.

Continuity: When Kristen falls into the quicksand, there's a shot of her from behind, and her back is covered in quicksand, although her back hasn't been in the sand yet.

Continuity: When Kincaid's dog is getting ready to pee it has its tail between its legs. When it cuts to the fake dog peeing flames, the tail is standing up.

Visible crew/equipment: After Freddy 'sucks' Sheila, Freddy says "You flunked", then it cuts to Alice trying to get out from her desk. Under her desk you can see someones fingers briefly.

Visible crew/equipment: When Dan pulls up in his red truck, before he goes into the restaurant, you can see the crew reflected in the side of the truck.

Revealing: After the truck has its collision with nothing, the chain yanking it backwards is visible.

Continuity: When Alice is in the cinema she has a drink of coke. The Coke has a plastic lid on it. But when Alice turns around to investigate the strong winds, there is no plastic lid on the Coke. Then in the next shot the plastic lid is back on it.

Continuity: The hole in the roof which Kristen makes when she falls through the roof changes size between the shots.

Visible crew/equipment: In the scene where Freddy's head is torn, if you play it slowly, you can see a sleeve and wrist coming out of the wall behind Freddy and pull the prosthetic head back.
