Sony Pictures Home Entertainment, £19.99

A wicked send-up of every musical biopic ever made, starring John C Reilly as one of the most iconic figures in rock history – Dewey Cox.

This story of a musician whose songs would change a nation.

Cox marries three times, has 22 kids and 14 stepkids, stars in his own 70s TV show, collects friends ranging from Elvis to The Beatles , and gets addicted to – and kicks – every drug known to man ... but despite it all, Cox grows into a national icon.
