Although Terrifier 2 substantially improved upon Terrifiers reception, Terrifier 3 will have a hard time replicating this success thanks to numerous factors. 2016s Terrifier was not a mainstream breakout hit for director Damian Leone. Earning 57% on RottenTomatoes, the intensely dark, brutal slasher earned around $400,000 upon release according to BoxOfficeMojo. However, the 2022 sequel to Leones killer clown horror was another story. Terrifiers modest success resulted in an Indiegogo campaign that funded Terrifier 2 which, alongside the support of BloodyDisgusting, brought the sequels budget up to $250,000. Terrifier 2 went on to earn over $15 million.
