Rock Star is a 2001 American comedy-drama film directed by Stephen Herek and starring Mark Wahlberg and Jennifer Aniston. It tells the story of Chris "Izzy" Cole, a tribute band singer whose ascendance to the position of lead vocalist of his favorite band was inspired by the real-life story of Tim "Ripper" Owens, singer in a Judas Priest tribute band who was chosen to replace singer Rob Halford when he left the band.^{[citation needed]}

Chris Cole (Mark Wahlberg) is a fanatical admirer of an 80s heavy metal band called Steel Dragon. By day, Chris is a photocopier technician and by night, he is the lead singer of a Steel Dragon tribute band called Blood Pollution (the name is taken from a Steel Dragon song).

Internal struggles among the actual Steel Dragon band members culminate with the firing of their lead singer, Bobby Beers (Jason Flemyng), and the starting of recruitment sessions to find a new vocalist. Chris experiences his own strife with his Blood Pollution bandmates, particularly guitarist Rob Malcolm (Timothy Olyphant). During a live performance, Rob's playing fails to live up to Chris' over-demanding standards regarding note-for-note accuracy to the original Steel Dragon recordings, and Chris sabotages Rob's amplifier mid-song - a fight breaks out between the two onstage. The next day, Chris arrives at Blood Pollution's rehearsal space (the basement of an X-rated theater) to find that he's been fired and replaced with his arch-rival, the (now former) lead singer of another Steel Dragon tribute band. Rob also cites Chris' inability to create his own musical style, preferring to remain the singer in a tribute band.
