"Halloween Horror Nights" at Universal Studios Hollywood, brings together the sickest minds in horror to immerse guests in a living, breathing, three-dimensional world of terror. The popular event features a new slate of unrivaled film and television production quality mazes, frightful scare zones and a fully re-imagined “Terror Tram” experience – all uniquely themed to today’s most definitive horror properties.

This year’s slate of mazes includes, “American Horror Story,” inspired by Ryan Murphy’s critically-acclaimed, Emmy and Golden Globe Award-winning television anthology series on the FX network; “The Exorcist: The Possession of Regan MacNeil,” based on the iconic supernatural horror film; “Freddy vs. Jason: Dream Battle,” inspired by New Line Cinema’s 2003 film that brought together the biggest horror icons in history: demented killer Freddy Krueger (A Nightmare on Elm Street) and notorious hockey mask killer Jason Voorhees (Friday the 13^th); “The Texas Chainsaw Massacre: Blood Brothers,” which pits guests against the unsavory wrath of manic killer Leatherface and his mentally unhinged brother, Chop Top; “Halloween: Hell Comes to Haddonfield,” an all-new maze inspired by the second film in the classic “Halloween” horror franchise; “Krampus: The Christmas Devil,” based on Legendary Pictures and Universal Pictures’ Christmas-themed horror film that brings to life the fabled anthropomorphic "half-goat, half-demon" horned creature who terrorizes those devoid of holiday spirit; “The Walking Dead,” an authentic living representation of AMC’s hit television series that takes the realism of the show to an entirely new level with the permanent attraction, as well as “Eli Roth Presents Terror Tram,” marking the first time ever that the signature attraction comes to life through the twisted mind of the filmmaker; and an all-new performance by the award-winning hip hop-dance crew Jabbawockeez.

Adding to the event’s intrigue, Universal’s most popular rides and attractions also will be open to guests, including “Transformers: The Ride-3D,” “Jurassic Park–In the Dark,” “The Simpsons Ride” and “Revenge of the Mummy–The Ride.”
