Christopher Walken to play Ozzy

Christopher Walken is to play Ozzy Osbourne in a new film.The 'Batman Returns' actor has a brief role as the wild rocker in 'The Dirt', which follows the career and outrageous antics of US heavy metal band Motley Crue.In one scene Walken recreates Ozzy's famous ant-snorting stunt, in which he hovered up a line of the insects mistakenly thinking they were cocaine.Motley Crue frontman Vince Neil lifted the lid on Walken's part in the film, telling ABC News Radio: "How funny is that going to be?"Other stars believed to be filming cameos for the movie include Val Kilmer - who played late rock legend Jim Morrison in 'The Doors' - and former Van Halen frontman David Lee Roth. Both will apparently play rock stars.The screenplay is based on Motley Crue's warts-and-all autobiography 'The Dirt: Confessions of the World's Most Notorious Rock Band', which documents the band's phenomenal rise to superstardom in the 80s, excessive drug use and womanising behaviour.
