Cool sh*t. Some questions: 1.)Is it based on the Ripper-Halford story with the original singer being gay and everything?If so Ripper has been portrayed unrealistically cuz Halford kicks his arse. 2.)I think I saw Zakk Wylde's name in the credits once the movie was over.Was I hallucinating or did he really play a role? 3.)What message does the first half of the film want to convey?That improvisation is bad and you've got to cover songs EXACTLY as they are? 4.)Who does Mark Wahlberg's vocals?He's got a Bon Scott voice!! Thanks.
