In the audition scene where Britney is dancing, behind her you can see a girl kick one of the cheerleaders - in the next shot you see it happen again.
When Britney first gets to Crinshaw Heights and runs in to Camille, you can see that Camille's bangs on the right side of her head keeps changing when the camera keeps cutting between the two of them. You can see that at first there is a long strand and then there isn't.
In the scene in the cafeteria where Camille, Leti and Kirresha are on the table showing their new cheer off, the leg of Leti's jeans changed in each shot. First the legs of her jeans are rolled up, and next we see they are right down. This happens at the end as well, the second last shot that has Leti in it, both legs are rolled down, and in the last shot, when Camille is speaking about the pep rally, one leg has been rolled up again.
Britney is in the lunch room sitting at the table and receives a cell phone call from her friends. When you can see the whole table with her lunch tray, at first you can see the Pepsi can, then the next you look it is gone.
During Britneys "krumping" lesson with Jesse and Ty, Britneys necklace changes positions several times when she is standing still.
At the end of the movie, when they are filming Rihanna's
video, they are shooting using a blue screen as can be seen on the monitors. If they were actually shooting with a blue screen, Rihanna's torso would have disappeared due to the blue color of her shirt.
At the homecoming dance, Britney takes out her earrings to fight with Winnie. In the next shot you see Britney with her earrings in.
Just before Winnie announces they are doing the Pirate Introduction cheer, the camera very quickly shows Britney putting her earrings back on.

During the final scene for the video shoot, there is a brief moment when a long shot is shown of the 3 to 4 person pyramid. In this moment, you can see that one of the girls at the top is not actually touching the top of the pyramid.
In the scene where Britney and the Pacific Vista girls are exchanging video messages, the background changes. At 12:20 Britney receives a video from her friends, the building in the background seems fine. But three minutes later, when the girls from Pacific Vista receive a video reply from Britney, it's noticeable that the sun is setting on the building.
Hayden Panettiere's surname is spelled "Panetierre" in the cast list in the end credits (but spelled correctly in the music credits).
When Britney is talking to Camille at the end before they cheer, she is wearing a pink sweat suit outfit. When the shots change you can see her string from her hood go from up on her shoulder to down in front of her and it keeps changing between shots. It's on her left (your right) as you're looking at the screen.
When Rihanna dismisses the judges before announcing the two finalists, she takes the microphone away from her mouth to clap but we still hear her talk as if she is speaking into the mic.
When Brittany is talking to the warriors, when they get off the bus for the competition wearing the pink outfits, Letti says "lets go kick some pv ass ya all" and Brittany's mouth says "OKAY" without sound, then the camera angle changes and she then says "OKAY" with sound.
