These include FX's critically-acclaimed, Emmy and Golden Globe Award-winning television series, American Horror Story, Stanley Kubrick's psychological horror film, The Shining and the upcoming SAW: The Games of Jigsaw movie. Roth is a long-time fan of Halloween Horror Nights and has previously served as a creative consultant for the event, including a Hostel-inspired maze. He said the commercial gave him the opportunity to combine a love of horror films with how those films are brought to life within Halloween Horror Nights. Here's what Eli Roth had to say about directing this commercial.

"I first got involved with Halloween Horror Nights as a fan. I felt that I was in a horror movie and I didn't want it to end. For this spot, I wanted to pay homage to these brilliant and scary films, and yet put my own spin on it."

Universal Studios' Halloween Horror Nights is the ultimate Halloween event. For more than 20 years, guests from around the world have visited Halloween Horror Nights in Hollywood and Orlando to become victims inside their own horror film. The streets of each coast's event are transformed into highly-themed scare zones where menacing "scare-actors" lunge from every darkened corner. Multiple movie-quality haunted houses are erected throughout the event, based on everything from iconic slasher films to hit horror television series to haunting original stories.
