Christopher Walken is to play Ozzy Osbourne in a new Hollywood movie. The Oscar winner will make a cameo role as the shock rocker in a new movie based on Motley Crue's 2001 autobiography THE DIRT, Crue frontman Vince Neil has revealed. The book, fully titled THE DIRT: CONFESSIONS OF THE WORLD'S MOST NOTORIOUS ROCK BAND, details the band's wild behaviour. Osbourne toured with the band and appears in the book snorting a line of live ants and taking LSD every day for a year. Val Kilmer is also lined up to play David Lee Roth in the film - but bandmembers Neil, NICKY SIXX, MICK MARS and Tommy Lee will be played by unknown actors. Neil says, "How funny is that going to be. We're doing big, giant cameos with those people."
