Trivia: During Joey's nightmare, he is seduced by a topless nurse who then captures him before turning into Freddy. As originally conceived, only her face was going to transform at first, thus having Freddy's burnt male head on top of an otherwise perfect topless female body in order to create an eerie, otherworldly look. The actress portraying the nurse even took part in some test shots and performed the scene under heavy prosthetics to make her face look exactly like Freddy's. However, the effect was cut as the crew felt it looked far too weird, and that it diminished the moment when Freddy fully appears on-camera in the scene.
Trivia: One of the best bargains that they got on an effect was when Kristen enters the nightmare house and sees a roasted pig that starts barking at her. The special effects guys were coming up with $300,000 estimates for how much a prosthetic pig would cost to build and animate; they could not afford that. Finally they got 2 REAL roasted pigs. One was decorated to look like it was ready to eat, and the other was made to look demonic. A crew member, who lost a coin toss, got under the table and stick his hand up into this dead pig to make it work. Glad it wasn't me...
