The Curse of Pandora's Box

Universal's Halloween Horror Nights (originally Universal Studios Fright Nights in 1991) is an annual Halloween-themed event at Universal Studios theme parks in Orlando, Hollywood, Japan and Singapore. The event was originally named Universal Studios Fright Nights in 1991 and began as a 3-night event at Universal Studios Florida. The following year, it re-branded as Halloween Horror Nights, advertised as the "second annual event". Since then, it evolved into a scare-a-thon event filled with themed haunted houses and scare zones, over the course of select nights from early September until late October/early November. The event was held at Universal Studios Florida from 1991 until 2001, when Halloween Horror Nights moved to Universal's Islands of Adventure in 2002. In 2004, a dual-park format was tested, which opened parts of both parks. Since returning to Universal Studios Florida in 2006, the event has been held yearly, with the exception of 2020, when it was canceled due to the COVID-19 pandemic, making it the first year that Halloween Horror Nights was not held since its inception. The event later resumed with its 30th year in 2021.
