Executive Meddling: A rare after-the-fact example. When the movie was in U.S. theaters in 1991, it ran 100 minutes, featuring many character moments and introductions (Maggie's foster mother doesn't just randomly show up near the end of the movie). However, for whatever reasons, New Line Cinema cut the movie down to 88 minutes for all home video releases, which unfortunately is all that has been available to this day. The German version of the movie, while cut down from the 100 minute version, also featured many of the scenes removed from the home video version.
What Could Have Been: Peter Jackson was asked to write a script for what would have been the sixth film: His idea would have started out with a weakened Freddy Krueger who no one takes seriously anymore, to the point where teens made a game of deliberately going to the dream world to beat him up. Once Freddy does start gaining power again, the main plot is kicked off by a boy having to enter the dream world to rescue his father.
John Doe is supposed to be Jacob from the previous film. When they could not secure the return of Lisa Wilcox (who played Alice), this was vagued up.
Earlier versions of the script had Freddy level up by absorbing the entire town of Springwood into the Dream World before moving onto the next town with the Dream Policenote the released spirits of the victims from Dream Warriors chasing after him.
