Trivia: In the hospital Heather is told that she can not be in a certain area without a pass; she replies "Screw your pass." The very same line was spoken, by her character Nancy in Nightmare on Elm Street 1, to a hall monitor in her dream.
Trivia: Wes Craven wanted to bring Johnny Depp in for a cameo as himself, as Depp had co-starred in the original "Nightmare on Elm Street", and this film featured cameos by various alum of the franchise.

Johnny Depp later stated that if Wes Craven had asked him he would have said yes.
