Question: Why is it that Tracy's hair keeps getting more and more highlights through scenes?
Chosen answer: It's common for filmmakers to subtly alter a character's appearance throughout the film to reflect how the character changes. In this case, as Tracy comes out of her shell, her personality becomes brighter, stronger, and more pronounced, and that is shown by her increasingly lighter hair.

Question: Is it true that the song "I Don't Dance" was specifically written for Corbin and Lucas because they both auditioned for the role of Ryan, but since Lucas was a better dancer, he got the part?
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.
Question: It's obvious that both Giselle and Edward know that jumping back into the sewer will get them back to where they came from, so why doesn't Giselle jump back in right away when she is first tossed into New York?
Answer: Obviously, Giselle didn't know. She was shoved into the wishing well by the hag and had no idea what had happened to her. Edward, being familiar with his stepmother's magic, was better prepared.
Answer: I believe her hair is also symbolic of white and black integration.
