'The Princess Diaries' (2001)
Newcomer Anne Hathaway showed her flare for physical comedy in her debut film. Based on Meg Cabot's series of kid lit novels, 'The Princess Diaries' casts Hathaway as Mia Thermopolis, an awkward, plain and unpopular teen who discovers that her grandmother (Julie Andrews) is actually the queen of the small European nation of Genovia, meaning that she is, in fact, a princess. Much ugly-duckling-to-beautiful-swan transformation ensues, and Hathaway's unthreatening beauty made her a heroine amongst the books' fans. The contractually-mandated sequel, 'The Princess Diaries 2: Royal Engagement', was met with considerably less enthusiasm.
