A new clip from A Nightmare on Elm Street called “All I Have To Do Is Dream” (watch after the jump) shows Jackie Earle Haley (as Freddy Krueger) terrorizing Rooney Mara, an actress who looks just like Emily Blunt when she’s scared and half of her face is encased in fiery lighting and the other half in darkness. Am I wrong? Other questions: I’ve never seen an Elm Street — does Freddy run or does he just calmly walk toward his victims? Seems to me she could’ve knocked some crap off the supermarket shelves to make it hard for him to run toward her and then bolted. But I’m guessing, from the close-up of her ripping off a portion of his shirt, that he needed to get close to her so she could do that and wake up from her dream with the piece of clothing in her hand? Am I close?!
