I'll admit it, as a kid Killer Klowns from Outer Space scared the heck out of me.
Long before ICP comes to earth, this bunch of goofy clowns, with a really great toy-based arsenal, land their space-going big top and get to making mayhem! A really useless cop, his love interest and the heroic Terrenzi brothers are all that stand between us, these man-eating clowns and their terrifying pop-corn. There really isn't much more to this classic terrible scifi horror, there doesn't need to be.
If you missed it when it was released you may have been among the fortunate!
