“Dark Arts at Hogwarts Castle” at Universal Studios Hollywood A brand new projection experience, “Dark Arts at Hogwarts Castle,” will be illuminating “The Wizarding World of Harry Potter” at Universal Studios Hollywood. According to the press release, this show will be more intense and dramatic, compared to the precious ones, “The Nighttime Lights at Hogwarts Castle” and “The Magic of Christmas at Hogwarts Castle.” Mixing light, special effects, and a new musical arrangement by William Ross (based on the original scores created by John Williams), visitors will witness the unleash of the darkest creatures and villains from the Potter universe. “As darkness falls on Hogwarts castle, Dementors™, Death Eaters and other unspeakable creatures from Aragog and Mountain Trolls to Thestrals will cloak the castle with sinister images from the darker side of magic—even conjuring the visage of Lord Voldemort™ himself, until the Patronus spell—one of the most famous, difficult and powerful defense of the Dark Arts charms in the wizarding world—is cast.” “Dark Arts at Hogwarts Castle” will run nightly from April 13 to 28, returning a few weeks later from May 25 to 27.
