The Celebrities Attending Halloween Horror Nights 2023 From Pedro Pascal to Billie Eilish

It's Halloween week, which means peak frenzy time at Halloween Horror Nights in Hollywood and Orlando. Guests are getting in their last-minute scares as Halloween Horror Nights 2023 runs at Universal Orlando Resort through November 4, while Universal Studios Hollywood gets ghoulish until October 31. And then the haunts disappear into the ether... For now. 

Among the rush of visitors at Universal Studios Hollywood were a lot of familiar faces, as plenty of VIPs from the film, television and the music world descended upon the park to get their screams on just like everyone else.

So we thought it'd be fun to take a look at just some of the many celebrities who made their way through Halloween Horror Nights in Hollywood this year to experience all the thrills and chills the park has to offer.
