We all know there are some quite prolific horror movie killers out there. These guys are at the top of their game and have been in the Killing Kids business for a hell of a long time- whether through a personal choice or just because they have nothing better to do with their time. Out of all the countless killers over the years though, there is bound to be a Number One out there who has racked up the most kills. So here we count down in order- the top ten killers with the most kills over their careers. 10. Pennywise The Clown - ITFilm Appearances: 1Kill Count: 9 This movie is the one reason why I cannot deal with clowns. I genuinely had to sleep with my bedroom light on after watching it for about two weeks. Pennywise feeds on children and gains his strength from the fear of his victims- he can shape shift into your worst nightmare, though he never did morph into a girls' restroom or anything crazy like that. It wasn't all bad though, he had a cycle- he would reawaken every thirty years to wreak havoc on the town of Derry, so if you survived into adulthood, chances are you were pretty safe. It was Tim Curry's excellent performance of Pennywise that really swayed me though. How can an actor go from being a transvestite in Rocky Horror go on to play the stuff of nightmares? Then after this terrifying role go on to play Long John Silver in the Muppet's Treasure Island?
