One of writer-director Mike Judge's favorite themes is American stupidity. His popular animated series Beavis and Butt-Head featured two brainless 15 year-olds obsessed with MTV. His 2007 film, Idiocracy, envisions a not-so-utopian American future in which evolution has bred the intelligence out of humanity. Judge's latest comedy, Extract, now out on DVD, revisits a second favorite subject — the American workplace. Where his cult classic Office Space pitted disgruntled office employees against their incompetent bosses, Extract focuses Judge's satirical eye on management.
