A Nightmare on Elm Street (1984) - 63 mistakes

Visible crew/equipment: When Freddy falls over the banister onto the stairs near the end, notice the crash mat he lands on.

Revealing: When Nancy is running up the stairs in her house to escape Freddy for the first time her foot hits the steps and go through the steps into some goop. Look at the steps above that step and you can see the pre-cut holes where the next sets of goop will be.

Visible crew/equipment: When Rod is being strangled by the sheet in the jail cell, watch as it goes around his neck and you can see the wire in the sheet that pulls it.

Visible crew/equipment: This is during the part where the girl dies in the bedroom with her boyfriend (where she gets dragged up along the roof). Just before, when you see the marks made by Freddy's glove, and her hands come up to show her pain, she clearly grabs a chunk of the thin latex pad (best viewed in slo-mo).

Visible crew/equipment: When Nancy's mother is pulled through the door window, a tape marker can be seen on the blue door, above the door handle.

Continuity: When Krueger smashes his arms out the front door window, large pieces of glass are still hanging in the window, but in the next shot, as he pulls Nancy's mother through, all the glass has disappeared.

Continuity: Keep watching when Glen sneaks through Nancy's bedroom window for the lighting in the bedroom. When the exterior shots are shown the light is always on but it is sometimes off inside!

Revealing: Near the beginning, during Tina's first dream, Tina gets cornered in front of one of the furnaces. She steps forward and Freddy jumps out from behind her and scares her. When she steps forward, Freddy (who is trying to lean down out of the shot) is seen stepping sideways to position himself to scare Tina.

Continuity: When Nancy is at her bedroom window, she says "OK Krueger, we play in your court" and she is holding her alarm clock. She then pulls down the blind, then when it cuts to inside, Nancy is walking over to her bed but isn't holding her alarm clock. If you look, the clock is on her bedside table, but she doesn't put it there.

Continuity: In the boiler room Nancy finds Glenn's bloody headphones. As she raises them up from the ground, between shots, the way she holds them changes.

Revealing: When Nancy sees Tina wriggling around in her body band and a centipede comes out of her mouth - you can see this is a doll that the centipede crawls out of.

Continuity: When Freddy jumps out from behind the tree in Tina's dream, his glove is on his left hand then it cuts away and back it's now back on his right hand.

Visible crew/equipment: Right at the end of the film, when Nancy's mother is pulled through the front door window by Freddy, you can easily tell it's a dummy!

Continuity: In the bath scene, Nancy is falling asleep and is awoken by her mother then starts falling back to sleep and her inflatable pillow is roughly 8 inches above her head. When the shot changes to face her, the pillow is now below her head.

Continuity: After Nancy gets out the bath, the big mirror goes from having slight condensation on it, to being covered in condensation between shots.

Continuity: When Nancy is in the boiler room towards the end of the movie, Freddy suddenly jumps out at her and scares her. In this shot Freddy is wearing his hat. Earlier in the movie Nancy takes the hat from in the movie. After the shot where Freddy jumps out at her with his hat on, the next scene is showed chasing her down a stair case without his hat.

Continuity: When Nancy gets out the bath, and after her mother leaves, she locks the door then leans back on the sink. Between a wideshot and following closeup, as she leans back, the way her towel and bathrobe are positioned (around her neck) changes. Also, into the wideshot she crosses her arms yet it the closeup her left hand is up by her shoulder.

Continuity: After Nancy wakes up from her nightmare in the dream clinic, her mother discovers her arm is scratched. The tape that was on Nancy's chin has gone, but returns in the next shot, only to disappear in the next.

Visible crew/equipment: When Nancy "jumps" from the boiler room to her front garden you can see her land in a pile of bushes. You don't even have to look closely to see the big black air mattress she lands on. It actually bounces above the fake bushes and becomes almost completely visible.

Continuity: When Glenn is in Nancy's room to wake her up, she awakes from the nightmare, her mother comes to the door and Glenn goes out the window. Nancy shuts the window behind him. After her mother leaves, the window is open.
