Audio problem: After the Robarazzi crew take pictures of Tori's armpits, in the next scene and many scenes after that, when they talk their lips don't match.
Continuity mistake: When the girl accidentally throws water on Jade, her face and hair are wet, but then when it goes back to the girl and then to Jade again, her face and hair are dry for a few shots, then when Jade goes inside the school in the hallway and Andre stops her, her hair and face are wet again.
Audio problem: When they start to sing the favorite food song, you can obviously tell they are lip syncing. If you look right when the kid starts filming them with his cell phone, you can hear Tori singing but her lips aren't moving.
Audio problem: When Tori wins the Kesha contest, when Kesha is singing, you can tell she's lip syncing because when she says "this place about to blow," she is just moving her lips, not singing.

Visible crew/equipment: When Sikowitz runs out of the classroom, a large television camera can be spotted at the side of the frame. (00:08:39)
Continuity mistake: Tori and Robbie take off their caps. In the next shot, Robbie's cap is back on.
Continuity mistake: Salt is visible on Jade's table before she gets the answer wrong and the salt pours on her from above.
Factual error: Tori donates three pints of her blood. There is no way that the hospital would have done this in real life seeing as it takes about eight weeks before a person can actually donate blood again.
Continuity mistake: When Jade asks Tori for help, Jade sits down with Tori's light colored pillow behind her. When it shoots Tori and then Jade again, the pillow is next to her instead. (00:11:30)
Continuity mistake: When the gang watches an advanced copy of "The Wood", and Jade watches the fake phone call between Beck and Tori, the background and scene changes from Beck at School, in the day, to Tori at Home, at night (viewable through windows) This isn't noticed by Jade. (00:13:30)
Other mistake: When the gang is trying to find the letters to spell Ke$ha at Tori's house, Robbie decides to go give the extra ice cream to the kids at the park. When he comes back he says that there were kids there with their moms, despite the fact that it is late at night, as we can see out of the window.
Plot hole: When Tori is at Nozu, in the tweet she states that she's using their computer, well, why didn't she use the computer or social media to contact someone at the school to come give her and Robbie $22?
Audio problem: When Tori fake hits Jade, the sound doesn't match up.
Answer: The Director hated working with Melinda, but knew that her superstar popularity and status would get his movie a big buzz and higher ratings. And the movie was discontinued for a re-audition to fill-in Melinda's leading/major role.
