Continuity mistake: At the beginning when Chris and his band go to the concert, they are in the front standing next to the stage. However, when the camera cuts to show the entire audience, different people are standing where Chris and his band were. From that view, Chris and his band are not even in the audience.
Trivia: 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.
