At Dean's funeral, Kris sees a photograph of her and Dean as children, but cannot recall ever knowing Dean before high school.

At the preschool, Quentin uncovers Krueger's hidden room and evidence that proves Krueger was in fact abusing all of the children; Krueger actually wants revenge on them for telling the truth.

Nancy decides the only way to end this is to pull Krueger out of their dreams and kill him in reality.

A Nightmare on Elm Street was primarily filmed in Illinois because of the positive experience the producers of Platinum Dunes had when filming other films in the same area.

Robert Englund, who portrayed Krueger in the previous eight films, voiced his support of the remake and the casting of Haley in the role.

On January 29, 2008, Variety reported that Michael Bay and his Platinum Dunes production company would be rebooting the Nightmare on Elm Street franchise with a remake of the original 1984 film.

In an interview, producer Brad Fuller initially explained that they were following the same line they did with their Friday the 13th remake, by abandoning the things that made the character less scary—the film's antagonist, Freddy Krueger, would not be "cracking jokes" as had become a staple of his character in later films—and focusing more on trying to craft a "horrifying movie".

That being, they decided to remove the one-line quipping Freddy, who had become less scary and more comical over the years, and bring him back to a darker nature; this included developing the character as a true child molester, something that Craven wanted to do originally in 1984 but changed to a child killer instead.

The decision was also made to bring Freddy's physical appearance closer to that of an actual burn victim, and the use of computer-generated imagery was used in certain sections of Haley's face to further assist in that vision.

Quentin uses the adrenaline to wake up Nancy, who pulls Krueger into reality.
