If you've always found clowns rather unsettling, we've got some bad news: you were right all along. This campy horror flick proves what we've always known - that those merry-making, make-up wearing, big-footed circus performers are actually homicidal aliens hell-bent on turning the human race into cotton candy coated snacks. Earth's only hope? A brave bunch of teenagers ready to stand up to popcorn guns, poison pies and the most terrifying smiles in the galaxy.
