From John Wayne Gacy to Stephen King’s It, history has offered plenty of reasons to fear Bozo. Fear of Clowns (2004) ups the ante by concocting a coulrophobe’s worst nightmare--a tale in which monsters in face makeup flash razor-sharp incisors and take delight in pummeling their victims. Blonde B-movie queens Lauren Pellegrino and Jacky Reres play would-be victims who must use all of their wits to survive a three-ring horror circus. They’re also kind enough to offer a sideshow attraction in the form of sumptuous skin shots.
