Visible crew/equipment: At the very end of the movie when they are singing in New York, you can see the camera crane for about five seconds right before the credits.
Continuity mistake: At the end of the performance of she's so gone Stella and Olivia suddenly switch sides of the stage.
Audio problem: In the song "Turn up the music" sometimes Olivia's mouth isn't moving when she sings.
Continuity mistake: Olivia is holding the sign that says "Back off the bash" she holds it with both hands. The shot changes she is holding it with one hand. Stella then takes a hold of one end. The shot changes and Stella is the only one holding the sign.
