Even those sung by Hilton, who blends surprisingly well into the mix as Amber, the vain, plastic-surgery obsessed daughter of Geneco's president (Paul Sorvino). The movie has a visual style that both works to its benefit and runs against the grain of conventional movie telling (comic strip look, richly colored and stylized sets, heavily filtered camera shots) and much of the music is surprisingly good.

Not everybody makes good on their payments, however, which is where Nathan Wallace (Anthony Head of Buffy the Vampire Slayer fame) goes into action as one of Geneco's 'repo men', brutally reclaiming defaulters organs at scalpel-point. Set against a futuristic backdrop where an epidemic of organ failures is plaguing humanity, people turn to the unscrupulous Geneco Corporation to purchase replacements for their failing vitals. The Director of Saw II, III and IV is hardly a person you'd associate with a rock opera, and when you factor in a cast that includes such artistic polar opposites as Sarah Brightman and Paris Hilton, you could be forgiven for feeling that the stink-o-meter would be going off the chart.

Big brass ones, it would appear, after viewing his twisted eclectic musical known as Repo! The Genetic Opera, which was given its world premier at Montreal's Fantasia film festival months in advance of its November release date.
