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...

At the very end of the first film, when Nancy is in the car with all of her friends the car goes driving off without their control. This is the same car that we see in this movie. It is the car in the junkyard that has Freddy's bones in it.
