12. Pennywise (It, 1990)
The Clown: In humanoid form, he’s very much a traditionalist, with a burst of red hair a stripy, frilly top and yellow trousers.
Why He’s Funny: Um… he has a funny… voice? Well, he’s played by Tim Curry…. Who… has an infectiously mischievous way about him? But that’s about it. We're frightened just looking at the picture.
Why He’s Terrifying: This is a pure force of evil that arrives in a small Maine town every 30 years to kill kids. Every scene he's in scares us more than the idea of being thrown in a room full of spiders, zombies and Paris Hilton clones. We're going to click on now, so we don't have to look at him anymore.
Oh, and he’s coming back.
