Don't be fooled by the sensationalistic title: the "killer" in question is not a homicidal maniac but a growing national epidemic - that of obesity. Grounded in deeply disturbing statistics - namely the fact that two-thirds of the American population (including 9 million children) qualify as obese or overweight - this documentary argues that the United States is on the cusp of an evolutionary disaster that is systematically wiping out large sectors of the populace. As such, the documentary traces the root causes and looks at ways to reverse this impending crisis. In making its case, the film draws on commentary from such public figures as Bill Clinton, Mike Huckabee, Arnold Schwarzenegger, Neil La Bute and others. ~ Nathan Southern, Rovi
