Chicago star John C Reilly is set to show off his singing skills again in a new film which parodies biopics such as GREAT BALLS OF FIRE, La Bamba and Walk the Line. The actor will play a fictional music legend called DEWEY COX in the spoof biopic WALK HARD. He says, "My character is an amalgamation of a number of classic musician stories, tales of excess, highs and lows and bad behaviour."
