Halloween Horror Nights has been cancelled this year at Universal Studios Hollywood in Universal City due to the coronavirus outbreak.

In a posting at the event’s website, the theme park operator said that the event would be cancelled at the Universal Orlando Resort as well.

“Universal Studios Hollywood continues to face ongoing business restrictions and uncertainty around its opening timeframe,” a statement at the website said. “Universal Orlando Resort will be focusing exclusively on operating its theme parks for daytime guests, using the enhanced health and safety procedures already in place.”

The Universal City theme park has been closed since March while the Orlando resort reopened last month.

Halloween Horror Nights is a popular attraction at the theme parks taking place in the six weeks leading up to Halloween. It includes horrific mazes and other scary attractions, such as encountering zombies from “The Walking Dead.” Last year, mazes were inspired by “Ghostbusters,” “Creepshow” and the film “Us,” from Academy Award-winning filmmaker Jordan Peele, among other movies and television series.

“We know this decision will disappoint our fans and guests. We are disappointed, too,” the website statement added. “But we look forward to creating an amazing event in 2021.”
