Director Wes Craven had intended to ask Johnny Depp to make an appearance as himself in the funeral scene. Craven never worked up the courage to ask him, but after the film's release, they ran into each other. Craven asked Depp if he would have made an appearance in the movie and Depp said that he would have, and that Craven should have asked him.
The television show appearance was inspired by a real encounter. According to Wes Craven: "Robert Englund and I did an appearance together on public television in the San Francisco area. It was about whether this kind of movie was bad for children or not. There were parents in the audience and then kids. All the kids leaped to their feet and started chanting, 'Freddy! Freddy! Freddy!' I remember looking at the show host and the parents, and they all looked horrified."
Before making this movie, Wes Craven watched all of the"A Nightmare on Elm Street" films. By the time he was finished, he claimed that he could not follow the storyline at all. He further regards the sequels to be weak compared to his original masterpiece.
Wes Craven was looking to get a specific reaction from Miko Hughes and his parents said there was a way to make him cry. His mother left the set and his father whispered in Miko's ear "your mother's dead."
The basic premise of the film, Freddy invading the real world and haunting the actors and crew responsible for the "A Nightmare on Elm Street" films, was originally intended to be used for A Nightmare on Elm Street: Dream Warriors (1987), but the idea was rejected by the studio at the time.
All of the earthquake sequences in the film were actually filmed one month prior to the Los Angeles quake of '94. The real quake struck only two weeks before the end of filming. Subsequently, a unit was sent out to film drive-by footage of actual quake damaged areas of the city before the end of filming. The cast and crew believed that the earthquake scenes that were filmed before the real quake struck were perhaps a bit overdone, but when viewed after the real quake hit, all were frightened by the realism of it.
There was a scene in the script that depicted a Robert Englund Freddy nightmare. The nightmare had Robert stuck in a spider-like web, and the new "demon" Freddy was a giant spider. This was dropped, because it didn't fit with the film's overall tone.
(At around one hour) The scene where Heather is dialing Robert Englund's house number on the phone in her car, the music tones that are played when she presses the buttons is the same as the A Nightmare on Elm Street (1984) theme.
This is the only film in the Nightmare franchise to feature orchestrated music during the credits, rather than a song like all the other films, including Freddy vs. Jason (2003) and the remake, A Nightmare on Elm Street (2010).
The "bio-engineered" hand and glove that Freddy uses in this film (as opposed to the glove used in the prior films) is actually derived from the artwork of the theatrical poster and video box covers of A Nightmare on Elm Street (1984).
(At around forty-four minutes) During the scene in the playground where Heather is talking about what happened at the funeral, right as she says, "Seeing Freddy in that grave seemed pretty real", a boy rides by on a bicycle wearing a sweater that is nearly identical to the one Freddy wears.
"Cuts and slashes" are a running motif in the film. As well as the clear cracks in the wall like a Freddy slash, there's also a claw-shaped logo on the first news reports of the earthquake, and the special effects firm is called "Cut to the Chase FX".
(At around one hour and twenty-four minutes) During the freeway scene, when Heather ducks for the tractor-trailer to go over her. This was done with a greenscreen. It took around one hundred takes to get the shot right. The next day Heather Langenkamp couldn't walk, because she was so sore from doing the takes.
The Nightmare on Elm Street movies and Friday the 13th movies are the only two slasher horror genres with more than 6 sequels of the early 90s making Jason and Freddy the two top popular horror villains of their time.
When Dylan crosses traffic to get home later in the film, Freddy was suppose to have a car with a razor blade on the front and was going to try to run the little boy down. Miko Hughes also starred in Pet Sematary (1989) where he was run down in a similar fashion.
Tracy Middendorf briefly played the role of Carrie Brady on Days of Our Lives (1965).The role was originally played by Christie Clark, who appeared in A Nightmare On Elm Street 2: Freddy's Revenge (1985).
When Robert tells Heather the fans would like to see them together again, she responds "In what a romantic comedy?" In which Robert responds "Just because it's a love story doesn't mean it can't have a decapitation or two" Englund starred in The Phantom of the Opera(1989) which is a tragic love story although Langenkamp doesn't costar. And it does have a decapitation or two.
