Pennywise the Dancing Clown - Terrifying white-faced clown on the TV mini-series "Stephen King's IT" (1990). Pennywise was actually the psychic projection of an alien creature ("It") living in the sewers of the small 1960s town of Derry, Maine. Every 30 years the creature awoke from hibernation and lured young children to their doom. The adults of the town were aware of the creature but strangely never interfered with its feeding. Then one day, seven local 12-year-old children (dubbed "the Lucky Seven") realized that evil lurked in their midst, and so they challenged the creature's hold on their town. After an initial encounter, the children believed they had defeated the creature, but thirty years later "It" reappears and kills more children. The murders alert town librarian Mike Hanlon (Tim Reid) - one of the former Seven - that once again "It" was alive. He quickly contacts his childhood friends and soon one-by-one they reluctantly return to their hometown to do battle. Unfortunately, Stanley is so terrified that he commits suicide in his tub - leaving the word "It" spelled in blood on the bathroom's tiled wall. Along the way, Pennywise appears to each of the surviving six and tries to scare them off. But undaunted by his attempts, the now determined adults fulfill their childhood oath to kill the creature. Along the way, librarian Mike Hanlon is attacked and hospitalized. In a final battle in the creature's subterranean lair, "It" reveals itself as a huge insect and the remaining five adults slay the alien beast for good. Eddie being the last casualty of the group ("It" kills him with his insect claws). Tim Curry (of The Rocky Horror Picture Show fame) played the role of Pennywise, the child killing clown.
