See What’s New in 2013 Universal Studios’ Halloween Horror Nights in this Photo Gallery Universal Studios’ Halloween Horror Nights is one of the best Halloween celebrations in the world. When you are walking your way out of one of the many highly elaborated mazes you are both scared and amazed at their creations. Yesterday, inside the studio, I had the chance to see up close some of the new costumes, masks and prosthetics that will bring to life properties like Chucky, Evil Dead, Insidious, The Purge, The Walking and more. In this exclusive photo gallery you can also take a peek at the “Hispanic monster” chosen this year, after the success of the ‘La Llorona’, El Cucuy (a.k.a. “El Cuco”, “El Coco”). Universal Studios’ Halloween Horror Nights open the gates of hell September the 20th.
