Continuity mistake: When Troy tells Chad that he wants to catch up on some homework and then heads to the audition, he's wearing jeans with thick decorative white stitching above his right pocket (viewer's left). However, when Troy raises his hand and volunteers to sing with Gabriella, he is wearing different jeans - the decorative stitching above the pocket is gone. (00:25:00 - 00:34:50)Super Grover
Continuity mistake: When Gabriella and Taylor walk through the cafeteria, Sharpay starts walking across the balcony to the stairs, cut to wideshot of the cafeteria and she is back at the center of the balcony with Ryan, motionless, but when it cuts to the next shot she and Ryan are already halfway down the stairs.
Chad Danforth: Have you ever seen Michael Crawford on a cereal box?
Troy Bolton: Who's Michael Crawford?
Chad Danforth: Exactly my point! He was the Phantom of the Opera on Broadway. Now, my mom, she's seen that musical 27 times and she put Michael Crawford's picture in our refrigerator. Not on it, in it. So, my point is if you play basketball, you're gonna end up on a cereal box. If you sing in musicals, you're gonna end up in my mom's refrigerator.
Troy Bolton: Why would she put his picture in her refrigerator?
Chad Danforth: One of her crazy diet ideas! Look, I don't have time to understand the female mind, Troy!
Chad: So, you're coming with me to the after-party, right?
Taylor: As in, like, a date?
Chad: Must be your lucky day.
Question: This is really bugging me: why is Gabriella suddenly wearing a red dress during the last song when everyone else is still in the same clothes?
