Loosely inspired by the true story of the heavy metal band Judas Priest, this music industry fable from director Stephen Herek is based on a script by actor-turned-writer/director John Stockwell. Mark Wahlberg stars as Chris Cole, a wannabe rock star who works by day as a copy machine repairman and by night as the lead singer of Blood Pollution, a Pennsylvania tribute band that imitates the best-selling heavy metal rockers of Steel Dragon. Although he's supported by his girlfriend Emily (Jennifer Aniston), Chris is devastated when his friends kick him out of the band he founded. His humiliation doesn't last long, however, as Chris soon learns that he's been tapped to replace the lead singer of Steel Dragon, literally becoming a rock star overnight.
Chris soon has everything he's ever wanted but is disappointed to discover that being a superstar isn't everything it's cracked up to be. Rock Star was produced under two other titles, "Metal God" and "So You Want to Be a Rock Star."
