Art the Clown gets a new partner in his murderous mayhem in Damien Leone’s Terrifier 3 in his former victim Victoria “Vicky” Heyes, whose mangled face is highlighted by disturbing, glowing, yellow eyes. The third chapter in the Terrifier saga saw Art the Clown return after a resurrection and five-year hiatus since the events of Terrifier 2, and once again he plagues the fictional Miles County with his particular brand of grisly massacre. While most of the movie features Art acting alone, his climactic rematch with Sienna Shaw is actually dominated by Vicky, with Art acting more as a henchman.
