Here's the wildly fun looking official trailer for the hillbilly/giant monster/alien bug movie The Millenium Bug (directed by Kenneth Cran). It's apparently totally free of CGI monsters for those who care about that sort of thing. It's currently in post-production for a 2011 release. Yes, I said hillbilly/giant monster/alien bug movie. There's so much awesome in that sentence. All I remember messing up at Y2K was an old VCR, which is obviously nowhere near as cool as this.
Synopsis: When the Haskin family seeks refuge from Y2K hysteria in the isolated forests of the Sierra Diablos mountains, madness and terror find them there. Abducted by a vicious hillbilly clan, the Haskins fight for survival, but neither they nor the hillbilly Crawfords can comprehend the monstrous nightmare about to erupt from the bowels of the earth.
