I watched the film again the other night and with an interesting theory. You
remmeber the opening where they had the montages from
previous "Nightmare" films? Remember when they showed Lisa, but she said
something different? I wondered if she probably said
that herself in a "Voice Cameo". Maybe that is why she and the others were
given "Special Thanks" at the end of the movie. Maybe
they were keeping it a secret for the fans to figure out later on. What do you
guys think? Did it sound like Lisa?
