With the advent of the Internet and online stalkers, the movie's themes have become more relevant than ever.
During the commentary, Wes Craven notes that the old prison where they filmed was later condemned for asbestos pipes. He comments they would all die of cancer. Not so funny after his death of brain cancer in 2015.
Special Effects Failure: Freddy's stretching arms look rather shaky by modern standards. The mom mannequin at the end doesn't hold up either. In two scenes where a character jumps, you can see the mattresses.
When Freddy is set on fire at the end, it is painfully obvious that it is a stunt double.
In the scene just before Tina's death where Freddy chops his own fingers off, causing green ooze to spew from the stumps, it is painfully obvious that the effect is not working properly: only his pinky bleeds the ooze, even though he also cut off his ring finger. The problem is even clearer if you watch Freddy's face as the effect occurs- Robert Englund's eyes quickly dart back and forth from the camera to the hand, as though he's nervously observing the flub.
Nancy: You know Tina, she dreamed this was gonna happen...She had a nightmare, that someone was trying to kill her. (breaks down sobbing) That's why we were there, mom. She just didn't wanna sleep alone.
Vindicated by Video: The movie did solid box-office business for a low budget 1984 movie, but it was the home video sales that really demonstrated what a money-maker Freddy could be.
