Visible crew/equipment: Towards the end of the movie when Whitney Houston is in her hotel room with Kevin Costner you can see the mic in a reflection in the window of the suite.
Continuity mistake: When Wayne and Garth are on their way to the Alice Cooper concert they show the car from behind you can clearly see that Garth is driving and Wayne is in the passenger seat but when they cut back to the car from inside Wayne is driving and Garth is in the passenger seat.

Continuity mistake: In the scene where the brothers are sitting at the bar, Cesar lights up a cigarette and is holding it in his right hand. The shot cuts as he slaps Nestor on the shoulder with his right hand and the cigarette is magically in his left hand.
