Revealing: When Troy says "I'll sing with her," Ms. Darbus turns around "in response" to his voice before he even says anything.

Audio problem: In "What I've Been Looking For", when Sharpay sings the last verse the first time around, listen closely as Ryan takes away the microphone. Her voice remains the same volume, and does not get any quieter as Ryan pulls away the microphone.

Revealing: During "Getcha Head in the Game" Right before everyone is about to do the big basketball dance the guy in the background to the left of the screen mouths "I Gotta" while Troy's singing them.

Continuity: When Troy tries to ditch Chad to go to the musical audition, he is wearing a belt (as seen when he is going down the school stairs) and white tennis shoes (as seen when he is almost caught by his dad when he rests against the side of the building). However when he makes it to the audition he is now wearing navy blue tennis shoes and no longer wearing a belt (as seen when he "volunteers" to sing with Gabriella).

Continuity: In the locker room scene where Troy walks in and his teammates confront him, Zeke describes the MVP in his picture, sits down, and puts the picture on the table twice.

Continuity: We see a close up of Gabrielle slipping in some milk, but in the wide shots there is no milk or carton on the floor.

Audio problem: In "We're All in this Together", you can hear either Troy or Gabriella's voice signing background, not matching the others' lyrics, but their lips are moving to the same words as all the others.

Continuity: When Gabriella is shown Troy on the laptop, dismissing the musical, she begins to cry. She still has wet tear streaks on her face as she looks out the window, but as "When There Was Me and You" begins, her face is dry.

Continuity: The post-callback basketball scene's countdown clock isn't accurate. If you try counting with it, you'll notice that it reaches 0 by the time that the ball's being passed to Troy.

Continuity: When Gabriella gets her picture taken on Troy's cellphone, she looks directly at the lens. When Troy looks at the picture, it's an angled shot of Gabriella and she's looking elsewhere.

Continuity: In the scene where Gabrielle and Troy are in the cafeteria after they have the fight, Gabrielle walks away from Troy to a lunch table with a tray in her hand and sits down. After a brief cut to Troy and the two traitors, there is a shot of Gabriella without a tray, followed by another shot a second later with the tray back again.

Continuity: When Kelsi trips over as she walks away from the piano, her composing sheets fall and scatter all over the floor, and by the piano. In the next shot the sheets are now suddenly all close to her so that she can pick them all up in this shot.

Factual error: In the scene where Taylor is trying to prove to Gabriella that Troy is a dumb jock who doesn't care about her, Troy is in the locker room with his friends. Troy's friends are recording Troy on a camera attached to a PC, and the image is seen on Taylor's PC. The message on Taylor's PC says an incorrectly spelled 'Recieving WiFi Signal' instead of 'Receiving'.

Continuity: Near the end of "Start of Something New" when Troy is saying "new" he moves the mike away from his mouth, but you can still hear him saying "new" before he puts it back to his mouth.

Continuity: When Troy and Gabriella are singing "Start of Something New" Gabriella's left sleeve moves up and down between shots during the scene.

Continuity: During the "Status Quo" number, we never see Gabriella walking through the cafeteria after she talks to Taylor unless it is a close up shot of her.

Audio problem: When Gabriella is singing "When There Was Me and You", when she sings the line "Like I could Sing Along", notice her mouth dosen't move.

Revealing: In the final scene "We're All In This Together", when Ryan is getting ready to jump off of the bleachers and be caught by his classmates, you can see Troy motion for Gabriella to move forward into the correct position for the shot.

Audio problem: When Troy and Gabriella are singing "Breaking Free" for the last time, Gabriella moves her mike away from her mouth numerous times, yet her voice never gets quieter.

Revealing: In the cafeteria scene, when Gabriella slips in the spilt milk, her tray is not only shot up, but tilted as well. However, after the camera cuts back to Gabriella, there is a cup of "sauce" yet it doesn't slide or tip off the tray.
