I own Killer Klowns on dvd.........just as with Backfire, it was a childhood favorite of mine. It has lost some of it's luster as I've grown older but still a fun watch. As for who came up with the concept, it's all the the dvd. I can't recall exactly but it is talked about in the featurette on the dvd.
Like the movie or not..........it does have the best title song for a movie, ever. The title song is so great. I'll pop in my dvd just to listen to the song play over the main menu. Circus meets new wave......ownage.
Killer Klowns has to be like the second most played movie on USA's Up All Night (if any of you remember it). Number one ofcourse would have to be Hardbodies........but Killer Klowns can't be too far behind it.
