America loves Cox! But behind the music is the up-and-down-and-up-again story of a musician whose songs would change a nation. On his rock 'n roll spiral, Cox sleeps with 411 women, marries three times, has 22 kids and 14 stepkids, stars in his own 70s TV show, collects friends ranging from Elvis to the Beatles to a chimp, and gets addicted to -- and then kicks -- every drug known to man... but despite it all, Cox grows into a national icon. The movie is a spoof of rock-star biopics, most obviously "Walk the Line," which borrows the element of the wife at home and the affair with the backup singer on the road. There's also a lift from "Ray," who, you may remember, was blamed for letting his little brother drown. Dewey Cox is out in the barn playing with machetes with his own brother one day when he inadvertently slices him in half. Life after that is never quite right for Dewey, whose father turns up at every triumph to remind him, "The wrong brother died." He develops into a musical prodigy who masters an instrument almost as soon as he picks it up and segues effortlessly from one genre to another in order to stay on top of the charts. Soul music? Bubblegum rock? Acid rock? Surfin' songs? Folk rock? He does it all.
