If I were to make a movie using only my own funds and a home computer, I probably wouldn’t be original enough to do anything other than wire a webcam into my Playskool murder shack. Thankfully, Australia’s Spierig brothers are considerably more inventive then I am. With 2003’s The Undead, they fused home made CGI with a host of science fiction and horror conventions in their story of a small Australian town besieged by both zombies and aliens. Six years later, the brothers are back with Daybreakers, in which a world populated entirely by vampires suffers a blood drought. Tonight, Sound on Sight takes a look at the Spierig’s two film, and we’re also going to have a round table discussion about the impact James Cameron’s enormously successful Avatar may have on the filmmaking landscape.
