Throw It In: Robert Englund improvised quite a few of Freddy Krueger's one-liners, but the best-known example happened in Dream Warriors, in a scene where Freddy emerged from a television set and killed a girl by smashing her head into it. The scripted line was "This is it, your big break in TV!" which Englund said on the first take. When the director went for an alternate angled shot however, Englund changed the line to "Welcome to Prime Time, bitch!" The different camera angle made it easy to edit the two lines together, and it became probably Freddy's defining one-liner. According to The Other Wiki, the line was originally "You're on TV now, girl!"
The script had Sally Kellman in the scene which featured Zsa Zsa Gabor.
Among the concepts and FX that had to be abandoned for various reasons:
Taryn's head was supposed to explode when Freddy stuck in the needles, but the gag wouldn't work correctly.
In the original script, one of the Warriors dreams up a giant Transformers-style robot to fight Freddy. The sequence even made it into the storyboards stage, but budgetary constraints made filming it impossible.
FX creator Mark Shostrom created a desiccated "little girl corpse" which Kristen would discover she was holding, but it was decided that the item was too grotesque. A miniature skeleton was used instead.
