Johnny Depp accompanied his friend Jackie Earle Haley to auditions for A Nightmare on Elm Street (1984). Instead of Haley being chosen for a role, it was Depp who was spotted by director Wes Craven, who asked him if he would like to read for a part. Depp got a part in that film, Haley didn't, but Haley would go on to play Freddy in this remake 26 years later.
The Freddy gloves were the most protected props on the set. Previous films had issues with the gloves being stolen. Most notorious was a glove was stolen from one of the films and appeared in Evil Dead II (1987) (see trivia for that film) hanging in a shed.
Robert Englund, the actor who portrayed Freddy Kruger in all previous films in the "Nightmare" series, gave a general approval of the remake, as he felt the story could be better told in 2010 with the use of CGI and other special effects that were not available in 1984.
Samuel Bayer turned down the offer to direct twice; he previously turned down several other Platinum Dunes films, including The Amityville Horror (2005) and Friday the 13th (2009). He relented after receiving a long email from producer Michael Bay, who said that doing the film would really open up his career opportunities.
The casting of Jackie Earle Haley as Freddy originally started as a rumor. During multiple interviews, Jackie acknowledged the rumors, stating that he would enjoy playing the character. He was eventually cast as Freddy.
The make up team wanted to make Freddy look more like an actual burn victim, and the crew had many reference photos of actual victims, which detailed how white the skin would appear after healing. They did not want the audience to "turn away in disgust" whenever Freddy appeared on screen, so they opted to take away some of the realism.
When filming first began, it took the make-up team six hours to apply the Freddy make up to Jackie Earle Haley. After a while the team was able to shorten the process down to approximately three hours.
Warner Brothers Pictures wanted the movie to be converted to 3D in post production a few weeks before the movies release, but the producers of the film augured the film wasn't shot with 3D cameras and the 3D wouldn't be good enough. After a heated debate, the producers and Warner Brothers came to the agreement the movie wouldn't be converted to 3D.
