Christopher Walken as Ozzy Osbourne?

It sounds like casting genius, even if it’s only a small role:

LAS VEGAS, Nov. 6, 2006 — Hide the Bats! Christopher Walken has agreed to play the ultimate bad-boy rocker — Ozzy Osbourne..

Motley Crue lead singer Vince Neil told ABC News Radio in an exclusive interview that the 63-year-old Oscar-winning actor will make a cameo appearance as Osbourne in “The Dirt,” a movie based on the band’s controversial 2001 autobiography.

“How funny is that going to be,” Neil told ABC’s Al Mancini at the Opening of Vince Neil Ink, the singer’s new tattoo parlor in Las Vegas.

Walken’s press representatives did not immediately return a call to ABCNEWS.com for comment.

“The Dirt: Confessions of the World’s Most Notorious Rock Band” set new limits in tell-all confessionals. The 448-page tome catalogues the drug and alcohol abuse, nasty infighting, and sex parties of Neil and band mates Tommy Lee, Mick Mars and Nikki Sixx.

Too bad it has to be in a movie about a band that I never liked. Even so, seeing Walken’s take on Ozzy might almost be worth the price of admission.
