I was checking out Christopher Walken's work on IMDB and there was this nugget at the top under "in production." Apparently he is 'rumored' to be playing Ozzy Osbourne and Val "Iceman" Kilmer will be playing David Lee Roth.
After Googling I now see that "The Dirt: Confessions of the World's Most Notorious Rock Band" is all about the rise of Motley Crue. This movis is slated for 2008.
Interesting. I wonder if there will be boobies in the movie.
