In 2001's "The Princess Diaries" was brought to life by Garry Marshall, with hilarious, hapless, unsuspecting PRINCESS Mia Thermopolis played by then newcomer Anne Hathaway. The movie set off a new trope in teen movies that cut straight to the heart of 11 -16 year olds everywhere - what if you really were a princess, but no one knew it? We talk about Princess Diaries, as well as the charming "What a Girl Wants" (2003) and drudgery of "Chasing Liberty" (2004).
