A Nightmare on Elm Street is a 2010 American supernatural slasher film directed by Samuel Bayer (in his feature directorial debut), written by Wesley Strick and Eric Heisserer, and starring Jackie Earle Haley, Kyle Gallner, Rooney Mara, Katie Cassidy, Thomas Dekker, and Kellan Lutz. Produced by Michael Bay and Platinum Dunes, it is a remake of Wes Craven's 1984 film of the same name, as well as the ninth overall installment of the Nightmare on Elm Street franchise. The film is set in a fictitious town in Ohio and centers on a group of teenagers living on one street who are stalked and murdered in their dreams by a disfigured man named Freddy Krueger. The teenagers discover that they all share a common link from their childhood that makes them targets for Krueger.

A Nightmare on Elm Street was originally to follow the same design as Platinum Dunes' other remake, Friday the 13th, where the writers took the best elements from each of the films in the original series and created a single storyline with them. Eventually, they decided to use Craven's original storyline but tried to create a scarier film. To that end, they decided to remove the one-line quipping Freddy, who had become less scary and more comical over the years, and bring back his darker nature. The writers developed the character to be a child molester, something that Craven wanted to do originally in 1984 but changed to a child killer instead. Freddy's physical appearance was changed with the use of computer-generated imagery to be closer to that of a burn victim.

Because of the positive experiences Platinum Dunes' producers had in the area, A Nightmare on Elm Street was filmed primarily in Illinois. Craven expressed his displeasure when he was not consulted on the project. Robert Englund, who portrayed Freddy in the previous eight films, voiced his support of the remake and the casting of Haley in the role of Freddy.

A Nightmare on Elm Street had its world premiere at Hollywood on April 27, 2010, and was theatrically released in North America on April 30, 2010, by Warner Bros. Pictures and New Line Cinema. Despite negative reviews, the film grossed over $63 million at the domestic box office and $117.7 million worldwide, making it the highest-grossing film in the franchise.
