Make sure when you watch Rock Star you stay for the credits!!! The crew of new rock movie Rock Star humiliated star Mark Wahlberg - by forcing him to listen to one of his old hits while he was filming a crucial scene. Wahlberg was just about to perform for thousands of extras - as Steel Dragon frontman Izzy - when, instead of the rock tune he was supposed to lip sync to, Marky Mark & The Funky Bunch's Good Vibrations was played over the sound system - complete with breakdancers who leaped onto the stage.

One crew member says, "Mark's expression was hilarious. I think for a moment his whole life flashed before him. He was mortified."

The scene was so funny, director Stephen Herek decided to keep the outtake in the movie - it's played over the credits at the end of the film.
