From Oct. 24 through Halloween night, Cirque du Soleil’s Michael Jackson ONE at Mandalay Bay will host its first Thrillerween, an eight-day celebration encouraging audiences to arrive dressed as zombies, ghouls, monsters, or the King of Pop himself.

The biographical film Michael, directed by Antoine Fuqua and starring Jackson’s nephew Jaafar Jackson, has made over $1 billion worldwide. It is now the highest-grossing biopic and music biopic ever and the biggest film in Lionsgate’s history. The movie opened in late April with $97 million in the U.S. and $217 million worldwide, making it the largest global debut for a musical biopic.
