Another interesting tidbit about Rockstar is, as previously stated in the episode, the film was loosely based on the replacing of Rob Halford in the band Judas Priest with Ripper Owens when Halford quit the band and according to the wikipedia page of the film there is a quote from the bassist of judas priest Ian Hill about the film which says,
"When Judas Priest bassist Ian Hill was asked about his reaction to Rock Star in an interview in PopMatters magazine Hill responded "Well, it was a true work of fiction, you know? When we heard about the production company were going to make a movie based, as far as we knew, about Ripper joining the band we offered our help. We said 'If there's anything you want to know, talk to us at the time.' And certainly our communication was cut off and that was it and they went off on their own tangent." Hill added "I mean, I quite enjoyed the movie. It was entertaining, you know?" Hill was quoted as saying "It had nothing to do with Rob Halford, Ripper Owens and Judas Priest, it's got nothing to do with that, whatsoever. It was fiction. Apart from the fact that 'Local Boy Makes Good'? That was the only true aspect of the movie." Hill was quick to add "I watched it once. I don't have the urge to watch it again."
It would seem that this film could have been actually interesting had they gone the more historical biographical route and actually told the story of Judas Priest, but instead they opted to go with the insane nonsensical story that they thought was somehow better. Just another case of Hollywood having a more interesting story that could have easily been told, but instead choosing one that fails to capture the interest of anyone whatsoever.
