Peter Jackson's original screenplay for Freddy's Dead saw Freddy aging and growing weak within the dream world. The teens of Springwood would have drug-fuelled slumber parties for kicks, and enter the dream world to beat him up.
In the last portion of the movie, from the point at which the lead female puts on the special glasses, to the time at which she takes them off, was originally filmed entirely in 3D. The effect was removed for most home video releases, but the UK rental version included the 3D effect in its entirety, with 5 pairs of anagylphic Red/Blue 3D glasses (similar to the ones in cinemas, but without the advertising) inside the box. The UK retail version was the standard 2D version and the cover artwork differed slightly from the rental one.
When shown theatrically audience members were given one pair of red cardboard 3-D glasses with movie taglines printed on it. The inside arms had adhesives for attaching to standard glasses. There was also an advertisement for House Party 2 (1991) printed on the outside of one arm.
When released to home video the 3D sequence was shown in standard format, excluding the UK rental version. However, the Laserdisc version had the full 3D sequence along with the regular version. 2 pairs of 3D glasses were included with the disc. The glasses were similar to the ones given out in theaters, minus the adverts, adhesives and taglines. They were also printed on a thinner cardstock. This was the only way to view the 3D sequence prior to the DVD release in the US.
A 16-year-old Jacob Johnson, the son that was born to Alice Johnson in the previous installment, A Nightmare on Elm Street 5: The Dream Child (1989), was a major character in the original script written for the movie by Michael Almereyda. In this first draft of the film, Alice, now in her thirties, was killed by Freddy. Taryn, Joey, and Kincaid from A Nightmare on Elm Street 3: Dream Warriors (1987) also returned as the "Dream Police." In the script, Taryn was the "Blade Cop," Joey was the "Sound Cop," and Kincaid was the "Power Cop." Director Rachel Talalay has stated that she greatly disliked original script and that the replacement script by Michael De Luca "saved the day." De Luca also said that he was surprised he wasn't asked to write the screenplay in the first place, since he had done a similar last-minute rewrite on 'A Nightmare On Elm Street: The Dream Child'.
Said to take place "10 years from now". The official NOES website's timeline opted for 1999 in place of 2001, despite the release date of the film in 1991, taking ten years from now to refer to the conclusion of A Nightmare on Elm Street 5: The Dream Child (1989). This actually impacts the placement of Jason Goes to Hell: The Final Friday (1993), since Freddy Krueger's claw emerged from the portal to Hell at the end of that film to seize Jason's hockey mask. This indicates that the defeat of Freddy in his film preceded the events of Jason Goes to Hell: The Final Friday (1993).
"John Doe" comes to think he may be Freddy's son. As noted earlier, this film takes place 10 years in the future circa 1999. The NOES official website's time line notes that Freddy Krueger's death at the hands of the Springwood parents took place in 1968 (based on the fact that in 'The Dream Child', Freddy's mother is said to have died soon after Freddy's trial). This film notes that Freddy's child was taken away from him in 1966 (see the chalkboard scene at Springwood High School). Therefore, John Doe would have to be in his thirties to be Freddy's son - which he obviously was not.
