This updated trailer for A Nightmare on Elm Street played before Clash of the Titans this weekend. It has a tiny bit of new footage in it, mostly of Aaron Yoo playing the same character he did in Disturbia, Friday the 13th, and 21. The number of cuts in this trailer have also been increased, bringing about a greater sense of uneasiness. Frankly I thought the glove with the razer sharp blades gave me goosebumps just fine. The glove and Aaron Yoo. Check out the more kinetic trailer after the jump.
