Continuity mistake: When Mr. Evans shows up in the helicopter, its blades are still spinning at a fast clip when he exits in the close-up. Problem is, the blades are not creating the distinct whirling shadow (nor is there any wind caused by the blades) on the surface of the red chopper, that we see in the two wideshots. (00:34:10)
Continuity mistake: After exiting the helicopter, when Mr. Evans is walking towards his family in the shot facing him, his golf club is in his left hand and swung over his left shoulder. Next close-up from behind, his club is in his right hand and over his right shoulder. (00:34:25)
Continuity mistake: Both Jason and Chad, who are wearing blue shirts and white aprons, are serving burgers, when Troy tells Chad that he wants Swiss cheese on his burger. Next shot in the kitchen, when Chad hands that burger to Zeke to add the Swiss, behind him Jason has been on kitchen dish duty wearing the green tee and blue apron. He can't be in two places at once. (00:57:55)
Continuity mistake: At the piano, Kelsi clutches the sheet music titled "Troy and Gabriella's Song" facing out, but when Sharpay grabs it, in her close-up the title is not written on either side. (00:58:35)
Continuity mistake: At the U of A basketball court, in the overhead shot Troy sits down beside a crumpled white towel, which disappears in his close-up as he calls Gabriella's cell. That towel returns in the subsequent overhead shot, when he continues to play basketball. (01:08:40)
Continuity mistake: During Sharpay's version of "You Are the Music In Me" after she tosses her red jacket atop the piano it moves from front to side, again and again, during the song. (01:12:25)
Continuity mistake: Before "Gotta Go My Own Way" in the kitchen scene, the bracelet on Gabriella's wrist is on her right wrist, but when she goes out to confront Sharpay, her bracelet is now on her left wrist. It stays on her left wrist until she gets to the lockers, then her bracelet is back on the right wrist and stays that way throughout the rest of the song. (01:13:50 - 01:19:55)
Continuity mistake: After winning the Star Dazzle award, Ryan hugs Sharpay with the trophy in his hand. Part of the star at the top breaks off (watch Kelsi's face as it flies past her), as the rest of the star on the trophy bends down. In the next shot the star is intact. (01:43:05)
Continuity mistake: During "All For One" at the pool party, mid-song the six singers split up into two groups of three - two girls and a boy and two boys and a girl; Sharpay, Troy and Chad walking down to their right (viewer's left) and Ryan, Gabriella and Taylor walking down to their left (viewer's right). Next shot, still singing and walking down, the three girls are walking to their left and the three boys are walking to their right. (01:46:20)
Continuity mistake: During "Work This Out" in the close-up when Troy sings, "A way to have fun," his name tag disappears, then reappears.
Continuity mistake: At the start, when the camera pans through the doorway, as Ms. Darbus speaks on the 'stage', there is nothing between Zeke and the doorway. In the next shot, a tall wood stool appears out of nowhere right beside Zeke. Also, the height and structure of the stool he is sitting on changes.
Continuity mistake: When Troy jumps into the pool, there is a huge colorful beach ball right beside Troy in the water, but in the next wideshot when Gabriella jumps in, the ball has vanished - and most of the pool is seen in this shot.
Continuity mistake: Before Vanessa Hudgens' stunt double is seen diving into the pool, you can see Vanessa already in the pool swimming towards Ashley Tisdale as she stumbles backwards into the water.
Continuity mistake: The shadows of the players during the baseball game change from shot to shot; sometimes they are behind the players and others they are in front of the players. Even though shadows change positions during the course of the day, this is too rapid and out of sequence for a normal afternoon.
Continuity mistake: In the scene when Troy and Gabriella kiss, when they are about to kiss for the second time, the wide shot shows Troy putting his hand on Gabriella's neck, but in the close-up she is seen putting her hand on his neck.
Continuity mistake: In the very first scene, before Jason asks Ms. Darbus about her past summers, the clock behind Ms. Darbus has the second hand close to the 9. However, after Jason asks his question, the second hand is back at the 7.
Continuity mistake: In the scene where Troy is playing basketball and Gabriella comes up to him, his jacket sleeves keep changing between being all the way down and being pushed up to his elbows.
Answer: It is just a coincidence. Corbin's character is all about sports and feels that Ryan is not in the same league when it comes to baseball (pardon the pun). Ryan, on the other hand, wants to prove that dancing takes just as much athleticism and dedication as sports therefore the game and song are a showdown between two cliques you generally find in high school, the athletes and the drama club.
