Freddy Krueger (Jackie Earle Haley) returns in “A Nightmare on Elm Street,” a contemporary re-imagining of the horror classic. A group of suburban teenagers share one common bond: they are all being stalked by Freddy Krueger, a horribly disfigured killer who hunts them in their dreams. As long as they stay awake, they can protect one another…but when they sleep, there is no escape.
