- B-Team Sequel: Wes Craven refused to work on this film because he never wanted or intended to have the first film become an ongoing franchise (and even wanted it to have a happy ending). He also didn't like the idea of Freddy manipulating the protagonist into committing the murders.
- The Other Marty: If you can believe it, Robert Englund was not initially asked to return as Freddy, because New Line thought they'd be able to use any old stuntman for the part and thus be able to pay him on the cheap. Within a week of filming, it was clear that the stuntman in question (whose name has never been publicly stated) was not up to the task; his movements have been described as more akin to Frankenstein's Monster than Freddy, and absolutely lifeless. He was fired and replaced with Englund, but a small bit of his footage remains in the shower scene. It works out well, since that scene is actually supposed to be Jesse doing the kill anyway.
- Throw It In!: The line "You've got the body... I've got the brains." was Robert Shaye's idea.
- Troubled Production:
- It started with the fact that the movie was greenlit the very weekend the first Nightmare came out. This may seem like standard procedure for sequel greenlighting nowadays, but back then, it was virtually unheard of, especially if this was an R-rated horror film.
- Then there was neither Heather Langenkamp or Wes Craven wanting to return- the latter feeling a sequel with her would contradict the Gainax Ending of the first movie, and Craven admitting to never wanting to direct a sequel. Craven did at least agree to consider directing the second film, but eventually backed out after hating the script that had been written without his involvement; he was replaced by Jack Sholder, who had acted as the de facto second unit director on the first film.
- Not making matters better was that Robert Englund wasn't even asked to return as Freddy - a random extra was hired... only for him to back out because he felt wrong taking it from Englund, who admitted that he disliked the experience of working on the sequel because he thought it went against the "bible" of the first film- he hated the idea of Freddy possessing someone to make them kill, and admitted he struggled with playing Freddy because of it.
- Actual filming went smoothly for the most part, although Mark Patton had large objections to the infamous "Touch Me" dance scene. Even despite being openly gay since before the film started production, he even thought the scene was too gay for him. He did his own choreography, which was far less campy than originally planned. Additionally, the climactic pool party massacre had actors not knowing when explosions were to go off- nobody was acting in that scene, their scared reactions were absolutely real.
- Fortunately, the film was a box office success, but wasn't anywhere near as well received as the first, and did make less money, with fans claiming the film broke a lot of what was set as rules in the first, namely that Freddy spent too much time in the outside world and that Freddy using others to kill for him went against the idea of his character. Fortunately, this forced Wes Craven to return for the next film, albeit as a writer.
- What Could Have Been:
- Brad Pitt and Christian Slater auditioned for the role of Jesse Walsh. Michael J. Fox was also considered, but he was busy with Back to the Future and Teen Wolf.
- The exploding parakeet's designer had initially made a demonic version of it for its scene. It was thought to look more silly than scary, so it was scrapped and replaced with a realistic puppet.
