Trivia: In the scene where Mia slips and falls on the bleachers, Anne Hathaway actually did fall. The director thought it was so funny that he decided to leave it in there. Notice how Mia and Lilly fall out of character and start laughing, but in the next shot they're immediately serious again as if nothing happened.
