The drummer of Steel Dragon was played by Jason Bonham, son of John Bonham, the late drummer of Led Zepplin.

In one part of the ending credits, you can hear a song called 'Good Vibrations' which is from Mark Wahlberg's 90's band, 'Marky Mark and the Funky Bunch'.

The references to Rock Star being base on the real life break up of the band Judas Priest throughout the film are numerous....Most notably in the montage of Chris Cole's life on the road with Steel Dragon he appears on the cover of 'Metal God' magazine several times. 'Metal God' was originally slated to be the title of the film which you can see on the "take" clicker during the outtakes while the movie's credits start to roll. Former Priest frontman Rob Halford is commonly referred to as the 'Metal God'. Halford was unceremoniously dumped from Judas Priest in the early 90s' for deciding to go public with the fact he was gay. Bobby Beers, Steel Dragon's first frontman in the movie, was kicked out of the band for amongst other reasons, being gay.

When the credits are rolling on the film, they show outtakes from filming the movie. In one of them, they are getting ready to shoot a concert scene, and when they yell "Action" to cue the music, instead of a Steel Dragon song coming up, they play a trick on Mark Wahlberg and play "Good Vibrations" from Marky Mark & the Funky Bunch. Pretty funny to see the look on Mark's face.

The guitarist in Steel Dragon is played by Zakk Wylde, former guitarist for Ozzy Osbourne and frontman for Black Label Society. He's very hard to recognise without his infamous beard.
