The haunted house coming to Halloween Horror Nights at Universal Orlando Resort tells part one of the story, and the house at Universal Studios Hollywood will tell part two, with the first part of the story set in Egypt and the second part set in the Limehouse District in London. With the creative teams at Universal Studios Hollywood and Universal Orlando Resort collaborating on the project, Murdy shared that the story of Universal Monsters: Legends Collide is split into two parts across the two parks. This past Saturday, John Murdy, Creative Director and Executive Producer of Halloween Horror Nights at Universal Studios Hollywood, shared further details about the house during a Halloween Horror Nights presentation at Midsummer Scream. The haunted house, which will be featured at both Halloween Horror Nights at Universal Studios Hollywood and Universal Orlando Resort, brings together the classic Universal Monsters, The Wolf Man, Dracula, and The Mummy, for the first time ever.

Earlier this year, Universal Studios announced an all-new Universal Monsters-themed maze for Halloween Horror Nights called Universal Monsters: Legends Collide.
