When a small town is invaded by aliens from outer space who are capturing and killing the townspeople, no one takes them seriously. Why? The aliens all look like circus clowns, use weapons that look clown like, and all have painted on smiles.  Aside from the dead-on cheesiness, the clowns themselves are probably the scariest you will see this side of It.  This is a MUST for any all-nighter and the best way I could think of to start off this article..

Regarded (by me) as one of the greatest cult classics of all time, Killer Klowns From Outer Space had a modest $2,000,000 budget, all of which went into production.  When the time came to create the costumes, the directors (brothers Stephen and Charles Chiodo) took to making themselves with relatively no cost, ultimately creating some of the scariest clowns for a movie that few would see until it found it's way onto USA's UP ALL NIGHT.
