Anna from Frozen. She's Rapunzel but somehow Turned Up to Eleven.
Mia in The Princess Diaries. Anne Hathaway was reportedly given the role after she slipped and fell off the chair during her audition. Funnily enough the part of the movie where Mia slips and falls off the bleachers was not scripted but was left in there because the director felt it was funny and still fit the character.
