In the original script, Freddy was a child molester. However, the decision was made to change him into being a child murderer to avoid accusations of exploiting a series of child molestations in California around the time of production.

The original glove was used in ‘A Nightmare on Elm Street 2: Freddy’s Revenge’ (1985), and later in ‘A Nightmare on Elm Street 3: Dream Warriors’ (1987) where it got lost. It’s rumored to be in possession of Robert Englund’s agent.

Fred Krueger was the name of a schoolmate of Wes Craven’s, with whom he had shared a paper route, and who had bullied him for several years.

Freddy was re-written as a child molester in the 2010 remake.New Line Cinema was saved from bankruptcy by the success of the film, and was jokingly nicknamed “The House that Freddy Built”.

All of the boiler room footage in the film was shot in the basement of the Lincoln Heights Jail in Los Angeles, which was condemned shortly after production wrapped, due to high levels of asbestos.

Wes Craven wrote the script and presented it in 1981 to try to sell it to a major studio, but no one wanted it. He said that “it just flew around” for three years until New Line Cinema picked it up.

The movie was shot in thirty two days.

Freddy’s appearance (especially the dirty clothes and hat) was inspired by a hobo, whom Craven saw staring at him through his window one day when he was ten.Amanda Wyss was handing out candy at her mom’s house on the Halloween following the film’s release and was surprised to see so many trick or treaters dressed as Freddy. She eventually told one of them that she played “Tina” in the movie, but he didn’t believe her.
